the regular checks of tire size, tread wear, air pressure,
car loading, looseness and wear before measuring car height, caster and camber, the car must be
kept at one level whenever measurements are made.
Do this operation the same way every time a measurement is to be made: bounce the car, front first,
then rear, several times by grasping the center of
the bumpers. Release the bumpers on the down
stroke each time after the same number of bounces.
CASTER AND CAMBER
Front suspension height must be correct before
measuring caster and camber.
After Solvent No. 1879318 has loosened any rust,
carefully loosen the upper control arm attaching
nuts while holding the bolts from turning. Once
caster and camber has been adjusted, a very small
turn of the bolts will affect the gauge readings.
Turning one bolt affects caster more than camber.
By bringing caster to approximate specifications,
then turning both bolts an equal amount in the same
direction to bring camber to the preferred specification, will usually bring caster to the preferred setting. Tighten nuts to 60-70 foot pounds torque using
Tools C-3675 and C-3696. However, due to length of
Tools C-3675 and C-3696 used with torque wrenches
Tool C-524 or Tool C-3005 a recalibration will be
necessary in order to obtain proper torque. Using
Tool C-3675, the torque reading on wrench must
show 45 foot-pounds torque, which is equivalent to
60-70 foot-pounds torque; and using wrench C-3696,
torque reading must be 55 foot-pounds torque, which
again is equivalent to 60-70 foot-pounds torque. Recheck gauge readings.

True-Level Torsion Aire produces a better quality
ride as well as maintaining a constant rear height.
The rear height is comparable to that of a car without True-Level Torsion Aire and with a three passenger load.
The compressor (depending on car model) (Fig.
4) is located either at the front of the engine or
above the fuel pump. The check valve is located in
the compressor head. A high pressure line from the
check valve is connected to the high pressure reservoir tank under the right front fender. A second high
pressure line connects the high pressure" tank to the
height control valve (Fig. 5) on the low pressure
volume tank. The low pressure volume tank is mounted between the frame side rails above the rear axle.
Two air springs from the low pressure volume tank
are connected to the two air spring pistons on the
rear spring plates. The height control valve actuator
arm is connected to the rear axle assembly by a rubber link.
OPERATION
With the engine running, the compressor maintains
220 + or — 20 psi air pressure through the air lines
and high pressure tank to height control valve end
cap.
(The amount of pressure is determined in the
design of the balanced head.) The check valve at the
compressor and the control valve confine the high
pressure when the engine is stopped.
The operating pressure in the low pressure volume tank and air springs is controlled by the height
control valve. The pressure varies with the load,
from approximately 20 psi with or without a driver
only load, through 70 psi with six passenger load to
approximately 90 psi for the Town and Country
models with a nine passenger load. Pressures within

this range vary instantly as the car moves over
chuck holes and expansion strips in the road surface,
in order to maintain the constant rear height. Since
these pressures are variable, it is not necessary to
test them.
The height control valve contains a minimum pres-
sure valve to maintain 8-15 psi in the air springs
SERVICE PROCEDURES
MAINTENANCE
The high pressure air tank (located under the right
front fender) should be drained at least once a
month. Depress the non-removable core in the drain
valve. (Should it ever be necessary to remove the
valve, remove the high pressure line at the check
valve FIRST.)
TESTING FOR LEAKS (Liquid Soap Method)
With the engine running, apply a diluted liquid soap
solution at the following locations where leaks would
cause bubbles: air springs and seats, height con-
trol valve mounting, air line connections, high pressure air tank, drain valve connection and outlet.
Stop the engine and remove the air line and check
valve from the compressor. Connect the air line and
check valve. Apply air pressure through the tank
drain valve. Coat check valve with soap solution. If
no leak is evident, wipe off soap solution before reinstallation.
Refrigerator Method (Refrigerant 12)
Add 150 pounds of weight to the center area of the
luggage compartment and raise car on a hoist. Discharge the high pressure tank by depressing the
valve core in the valve. Remove the minimum pressure valve from the height control valve. Disconnect
the rubber linkage from the differential housing
bracket and move the actuator arm manually to discharge all air from the low pressure volume tank.
With all air removed from the system, connect the
rubber linkage and install the minimum pressure
valve.
Install adaptor Tool C-3693 between the high
pressure air line and the compressor check valve.
Connect manifold gauge set, Tool C-3627 (used with
air conditioning) on adaptor, Tool C-3693, using
the gauge set suction hose. Attach the refrigerant
tank to the gauge set. Open the suction side of the
gauge set and charge the system with 40 psi of refrigerant 12. Shut off the gauge set and start the car
during a no-load operation as in changing tires by
use of a bumper jack. This pressure prevents damage to the air spring as the jack is lowered and a load
condition restored to the system.
The height control valve also contains a high pressure relief valve (150 psi) to protect the system
under extreme heavy load conditions.
engine. Operate the car engine until normal operat-
ing pressure of 200 + or — 20 psi is obtained.
Using leak detector, Tool C-3659, (used with air
conditioning) check the entire True-Level Torsion
Aire System for leaks and make all necessary repairs.
CAUTION
Be sure no gasoline is leaking from the car system
when checking the True-Level Torsion Aire System
with Tool C-3659.
With the car engine running, purge the refrigerant from the system by disconnecting the rubber
linkage from the differential housing and manually
operating the height control valve actuator arm.
With the refrigerant purged from the system, connect the rubber linkage to its bracket. Shut off the
car engine and again discharge all air from the high
pressure tank. Remove adaptor Tool C-3693 from
the air line and check valve. Connect the air line to
the check valve. Lower the hoist and remove the
weight from the luggage compartment. Operate the
car engine approximately three minutes before removing the car from the hoist.
CHECKING
The vehicle must have recommended tire pressures,
full tank of fuel (or equivalent weight added to luggage compartment over the tank). (Gasoline weighs
approximately 6% pounds per gallon.) The front
suspension height should be correct and equal on
both sides before placing car on level floor with no
passenger load.
The rear suspension height must be set to a speci-
fied vertical distance between, the top of the axle
housing and highest part under the axle bumper
straps,
sides of the car (Fig. 6). Clean the bumper straps
and axle housing tubes before measuring.
Rear suspension height is measured (both sides)
twice, once with load and again without load. Both
pairs of figures are compared as well as averaged.

Fig. 6 — Checking Rear Suspension Heights
The four figures are also averaged. Run the engine
three to fiwe minutes to assure proper pressure in
the system and proceed as follows:
a. With engine running, add 150 to 200 pounds of
load to center of luggage compartment. The height
control valve should feed additional air to the low
pressure system, causing car to return to original
height.
Measure height at both sides using Tool C-3670,
and record the figures. The difference should not ex-
ceed */2 inch. If greater than % inch, recheck the
front suspension height, particularly the difference
between the two sides, and reset if necessary. If
rear height difference still exceeds */2 inch, inspect
rear springs, (for spring specifications in this supplement). When difference is under
y%
inch, average
the two figures for use later. This is Step (a).
b.
Remove added weight from compartment and
allow height control valve to bleed the system for approximately three minutes. The engine may be shut
off during this operation.
Measure rear heights and average the two figures.
The difference between this average and the average
obtained in step (a) above should not exceed % inch.
(This difference is called the height control valve
correction error.) Adjust valve if necessary.
Average the four measurements. (Do not average
the two averages.) The average should be 4% inches

CHRYSLER SERVICE MANUAL
Reassembly and Installation
With piston upright on bench, place small end of air
spring over rounded end. Roll spring down to cover
piston completely (Fig. 8). Insert retainer bolt assembly and examine for snug fit in piston.
Remove rear shock absorbers. Make hold down
straps or use Tool C-3694 straps (Fig. 9) and install
them in place of shock absorbers. Strap will hold
weight of body on leaf springs and assist in seating
air spring.
Position piston and air spring assembly on spring
plate. Install retainer bolt, washer and nut (Fig. 10).
Tighten to 5 foot-pounds torque temporarily. Coat
mounting rim of air spring with diluted liquid soap.
If both springs were removed from the low pressure
volume tank, it will be necessary to install both
simultaneously.
Start the engine. Hold air spring (s) tightly in
position against tank seat (s) and operate control
valve manually. Air pressure entering air spring (s)
will force spring up on its seat.
Cleaning and Inspection
Clean all parts with clean, dry cloth. Inspect piston
and mounting bolt assembly for nicks, burrs or
cracks. Remove burrs with crocus cloth. Replace a
cracked piston with a new piston.
Mounting bolt assembly must be a snug fit in pis-
ton and retainer section must seat solidly against
piston. If necessary, peen piston around bolt hole to
obtain snug fit.
Inspect air spring for cuts, cracks, holes and ex-
cessive carcass wear. Install a new air spring if
necessary, however, small surface cracks in outer
rubber cover are permissible provided there is no
leak.
CROSSMEMBER
NUT
Check seating of air spring on tank flange and
seating of piston on spring plate. Align piston and
tighten nut to 100 inch-pounds torque. Piston alignment can be checked by depressing around wall of
air spring and noting if piston is properly centered.
Remove hold down straps and install shock absorbers.
Connect actuator arm to rubber linkage. Check
for air leaks paragraph "Testing for Leaks." Check
car heights.

CHRYSLER SERVICE MANUAL
TOTAL CONTACT SERVICE BRAKES
Servicing procedures outlined in the 1958 Chrysler
and Imperial Service Manual, D-16350, will apply
to the 1959 models with the exception of the removal
and installation of the new brake shoe retainer.
All brake shoes have a coil spring type guide. The
guide retainer pin extends through the dust shield,
the web of the shoe, a flat washer, the coil spring and
the cupped retainer.
Removal — While holding retainer pin in dust
shield, push retainer toward brake shoe, turning the
retainer to unlock it from the pin.
Remove retainer, spring and washer from pin.

While holding retainer pin in dust shield, push retainer toward brake shoe, turning the retainer to
lock it on the pin.
MASTER CYLINDER
The master cylinder used with power brakes has an
adjustable pushrod. A new master cylinder assembly
is used on Chrysler Models without power brakes.
The new master cylinder has a non-adjustable
push rod-and-piston stop which is permanently attached to the piston. The boot retainer is also a part
of the assembly. The assembly is attached to the
mounting face of the master cylinder body with two

screws. No attempt should be made to disassemble
this push rod and piston.
The combined action of the piston return spring
and the pressure in the master cylinder is sufficient
to hold the brake pedal in the "off" position, without
a pedal return spring and pedal stop. The brake
pedal should never be pulled back beyond the limit
controlled by the piston stop. A minimum pull of 50
pounds could pull the piston off the push rod.
PISTON TYPE POWER BRAKE UNIT
The 1959 Chrysler and Imperial Models will have
both the "Bellows Type" Power Brake as well as the
"Piston, Type." The servicing procedure for the "Bellows Type" is the same as that in the 1958 Chrysler
and Imperial Service Manual. The servicing procedure for the "Piston Type" is outlined below:
The piston type power brake is an oval-shaped
air-vacuum unit (Fig. 21) mounted on the engine
side of the dash panel and is connected mechanically
to the brake pedal linkage through the power unit
push rod.
A yoke at the end of the piston rod is in contact
with the power lever pin of the reactionary linkage.
The valve operating rod is located at the center of
piston rod and is always in contact with a ramp at
the upper end of the valve trigger arm of pedal linkage.
A control valve operating rod (Fig. 21) moves
within the piston rod to actuate the vacuum valve
and poppet.
The mechanical contact between the power unit
and the brake linkage exists only when the power
unit is assisting in a brake application. In the event
there is a loss of engine vacuum, the brake pedal is
free to function independent of the power unit to
apply the brakes in the conventional manner.
PEDAL LINKAGE ADJUSTMENTS (ON CAR)
It should seldom be necessary to adjust the brake
pedal trigger arm. Adjustment, however, may be
necessary, occasionally, to eliminate the following
conditions:
If the pedal pressure releases slowly, adjust by
rotating the adjustment screw in a counter-clockwise direction. A time delay (noted during a fast
brake application), can usually be corrected by mak-
ing a clockwise adjustment on the adjusting screw.
Should the pedal vibrate (booster chatter), turn the
adjusting screw in a counter-clockwise direction.
NOTE: Rotation of adjustment screw should be
limited to plus or minus 90 degrees about original
setting.
ASSEMBLY OF PEDAL LINKAGE IN PEDAL BRACKET
CAUTION
Use extreme care during assembly or handling of
the linkage as the power brake pedal trigger arm is
easily damaged.
After reinstalling the brake pedal linkage in the
pedal bracket, a wooden wedge should be placed between the power brake lever and the forward edge
of the triangular hole in the pedal bracket (if power

unit has been removed). This will prevent the trigger arm from extending beyond the extremities of
the bracket.
LUBRICATION
Except for an occasional few drops of SAE 10W Engine Oil on the power brake lever pin bushings, the
brake pedal linkage requires no further lubrication.
The power unit will require no lubrication under
normal usage.
PEDAL FREE PLAY ADJUSTMENT
After the master cylinder, booster, and pedal linkage are completely installed (and wooden wedge removed), a free play adjustment check should be
made at no vacuum as follows:
NOTE: Removing vacuum hose and pressing the
brake pedal several times will aid in obtaining the
no vacuum condition.
Insert the blade of a screw driver between the
rubber collar of the power brake trigger pivot and
the rear side of elongated hole in the power brake
lever, forcing them apart.
NOTE: If the brake pedal and the power brake lever
are not wedged apart, a false free play setting (which
GAUGE
BLOCK
(TOOL)

includes booster valve travel) will be measured at
the pad end of the pedal.
Check free play with linkage in this position by
pushing lightly at the pad end of the brake pedal.
Pedal free play travel should be between 1/32 and
Vs inch. If pedal free play movement does not come
within the required limits, adjustment is made by
lengthening or shortening the push rod as required.
ALTERNATE METHOD OF MEASURING PEDAL
FREE PLAY
Remove master cylinder push rod end pin. Using
light finger pressure, move push rod forward until
contact is made with the master cylinder piston. Attempt to insert the push rod pin through the
power lever and push rod end hole. If the push rod
must be pulled back to allow passage of the push rod
end pin, free play is present.
If the push rod must be pushed further into the
master cylinder to allow passage of push rod end
pin, no free play is present and an adjustment must
be made at the push rod.

duced generator charging rates, and greatly reduced
belt life. To avoid any such adverse effects, the following service procedure should be followed:
1.
Adjust all belts "in use"* to the specified belt
tension at new car preparation.
2.
Readjust all belts at the 2,000 mile inspection
and service.
3.
Check all belts by the deflection method at serv-
icing and readjust if needed,
4.
The new belt tension specifications should be
used on all new belt installations and the above procedure followed thereafter.
There are two methods by which belt tensions can
be properly established:
Torque Method — All generator and power steering
pump belts can be tightened to the specified tension
(see Tension Specifications that follow), by use of a
torque wrench. The generator belts are tensioned by
using a special tool C-3379, and torque wrench. The
power steering belts are tightened by inserting the
torque wrench in the square hole provided in the
bracket. Other belts can also be tightened by this
method if the adjusting bracket has a square hole.
To tighten belts by the torque method, loosen all
mounting bolts and apply the specified torque to the
accessory or idler. Tighten all mounting bolts while
the torque is applied to the accessory. If it is not possible to use the torque wrench because of clearance,
use an extension.
Belt Deflection Method — All belts can also be adjusted by measuring the deflection of the belt at the
mid-point between two pulleys under a five-pound
push or pull. A small spring scale can be used to establish the
five-pound
load. See Figure 29 for correct
location at which to measure deflection.
This method should be used only when it is not
possible to use the torque method, as it is a less accurate method. To tension the belts by the deflection
method, loosen all mounting bolts and use a bar to
apply tension to the belts being careful not to damage the accessory. A Johnson bar can be used if the
accessory has a square hole. Tighten the mounting
bolts and check the deflection, (see Belt Tension
specifications). It may be necessary to repeat this
procedure several times to establish the correct tension.
* Any belt that has operated for a minimum of a
half-hour is considered to be "in use."
