INSTALLATION INSTRUCTIONS
600 Series Overhung-mount Pedal Assemblies
Description
The Tilton Overhung pedal assembly has been designed to provide the driver with
the greatest control and comfort from a swing-style pedal assembly. This system al-
lows the mounting of the master cylinders and reservoirs in the driver’s compartment
away from the heat of the engine.
Finite Element optimized pedals provide strength, stiness, and durability to handle
the most severe braking conditions. Adjustable foot pad positioning allows custom-
ization for dierent drivers.
The pedal assembly is set up for dual brake master cylinders and includes the balance
bar assembly. This allows adjustment of the brake pedal force distribution between
the two master cylinders. This system can be used to compensate for fuel load
changes, tire wear, and changing track conditions.
The Remote Brake Bias Adjuster is available as an option. This connects to the balance
bar allowing the driver to make balance bar adjustments quickly while on track.
Fluid reservoirs can be directly mounted to the master cylinders or can be remotely
mounted based on your application. It is important to follow these setup instructions
closely to realize the benets of this design.

installation notes
• The pedal assembly must be attached to a very rigid frame structure.
• The mounting location should suit the driver and also provide a stable
platform.
• Be sure that there is no binding during the full stroke of the master cylin-
ders when the pedal is depressed.
• The balance bar mechanism must clear all obstructions when the balance
bar is adjusted to the extreme right or left-of-center and at full stroke of
the master cylinders.
• If you have decided to remotely mount the reservoirs, select the location
for the reservoirs before starting installation.
• This is a gravity fed system, so the reservoirs must be located above the
master cylinders.
• Attention must be paid to the routing and location of the hydraulic lines.
Avoid heat sources such as exhaust pipes.
• Accurate clutch pedal setup is critically important. Improper clutch pedal
installation and/or adjustment can result in expensive clutch damage
and DNFs at the track!

installation
1. Set the clevis center-to center distance at 2.620 +/- .040". You need
to do this before attaching the master cylinders.
2. Thread the adjusting shaft left or right until the spherical bearing
is near the center of the pivot sleeve. Note that the right end of the
balance bar has a longer threaded section and will stick out farther.
3. If you are using a remote adjuster, remove the jam-nut from the
adjusting shaft. If you are not using a remote adjuster, tighten the
jam-nut against the barrel nut on the longer end (right end) of the
shaft. The round end goes against the barrel nut.
4. Mount the pedal assembly in the car. It is important to mount the
frame rigidly so that it does not move when heavy pedal force is
applied to both pedals. See diagrams 5–8 for mounting hole loca-
tions. The four large through holes are for attaching to the main
support structure while the two tapped holes and the six master
cylinder mounting studs can be used for additional stiening.
5. (Aluminum Pedals Only) Attach the two foot pads. Dierent
osets are available by turning the pad upside down. Choose only
positions that allow connection with all four screws per foot pad.
6. If you are going to bench bleed your master cylinders,
now is the time.
7. Bolt the master cylinders into place with the supplied 5/16"-24
serrated ange nuts. Make sure the master cylinder pushrod has a
jam-nut.
8. Thread the master cylinder pushrods into the clevises equal
amounts (you may need to alter this later) until the pedal foot
pad is in the correct position for the driver (See Diagram 2). A
minimum of .25" thread engagement (6 threads) is recommended.
9. Tighten the master cylinder pushrod jam-nuts against the clevises.
10. Make sure that the chosen pedal position allows a full 1" of stroke
at both master cylinders.
11. Make sure that the adjusted position also allows both master
cylinders to return to their fully relaxed position without binding.
Preload on the master cylinder pushrods can cause the brakes to
lock up when hot when there is no force on the pedal.
12. Attach the hydraulic lines.
13. Attach the reservoirs and bleed as directed in the master cylinder
directions. With a balance bar, always bleed a front and a rear
caliper at the same time to insure total air removal.
14. Apply the brakes and adjust the pushrod length so the adjusting
shaft is parallel to the master cylinder mounting surface (See
Diagram 3). If one pushrod is shortened by one revolution,
lengthening the other by one revolution will maintain the same
pedal position. Do not extend the pushrods to the point where
they preload the master cylinder pistons. After adjusting, tighten
the jam-nuts on both pushrods.
15. You will need to test drive the vehicle to determine if
adjustments need to be made to the brake bias (front/rear brake
force distribution). See Section F for making bias adjustments.

Distance from the rewall must be great enough
that a full stroke of the master cylinder is possible.
