Important Precautions

• Always read carefully and understand instruc­tions prior to using this equipment

• Brake fluid is highly corrosive. Wear gloves and
approved safety goggles at all times, and pre­vent contact of the fluid with painted surfaces.

• Consult and follow the vehicle manufacturer’s
recommended procedures when servicing any
hydraulic system.

• Do not use this unit with flammable liquids or
with fluids at temperatures above 175° Fahren­heit (80° Celsius).

• Properly dispose of old fluids, and replenish hy­draulic systems with new brake fluid from freshly
opened containers.

• Do not attempt to pressurize the bleeder/evacu­ator. It is designed for vacuum use only.

• This unit is equipped with an automatic shut-off
device that will prevent fluid from entering the
compressed air stream and ejecting through the
exhaust. However, if the unit is continuously op­erated when the reservoir is full, residual pres­sure will allow the reservoir to completely fill with
fluid, creating the potential for spillage when the
lid is removed. To prevent this situation, empty
or turn the unit off prior to filling the reservoir
completely full.

©

The screws included in Base Kit 822701 are

•
provided to secure the base to a work surface.
Do not use the screws to attach the base to the
reservoir.

Principal of Operation

This unit is designed for use as a vacuum brake or
clutch bleeder, or fluid evacuator. It utilizes com­pressed air between 60 psi (4.1 bar)and 150 psi
(10.3 bar), and a venturi system, to build vacuum
in the reservoir. By attaching the proper accessory
to the coupler located on the top of the unit, the
vacuum can be used to drain brake fluid from a hy­draulic system such as the brake or clutch systems
on an automobile. It can also be used to evacu­ate a variety of fluids from reservoirs including the
master cylinder or those for power steering fluid or
engine coolant.

An automatic master cylinder refill kit is included
with this unit. It is conveniently designed for use
with a standard bottle of brake fluid, to maintain an
adequate fluid level in the master cylinder while the
hydraulic system is bled. Instructions are included
with the kit for its use.

Instructions for Bleeding Brakes

IMPORTANT: This unit is designed for servicing a

variety of vehicles in a safe, convenient manner.
However, options such as load sensors or anti­lock brakes, available on many automobiles, may
require additional steps or equipment to perform a
proper service job. The procedures below are to
serve as guidelines for the use of this equipment,
in addition to these guidelines, always follow the
manufacturer’s recommended procedures when
servicing each unique vehicle.

Removing old fluid from the brake mas­ter cylinder

1. Properly park the vehicle on level ground and
turn the engine off.

2. Clean the exterior of the master cylinder and
master cylinder cap to prevent dirt from entering
the master cylinder when the cap is removed.

3. Remove the cap from the master cylinder reser
voir.

4. Connect clean, regulated (60 psi (4.1 bar) to 150
psi (10.3 bar)) compressed air to the male quick
disconnect nipple attached to the swivel air
inlet, located on one end of the vacuum bleeder
handle.

5. Connect the appropriate end of the evac tube
assembly to the female quick disconnect cou­pler located on top of the vacuum bleeder.

6. Insert the other end of the evac tube assembly
into the master cylinder fluid reservoir, and push
the vacuum bleeder throttle forward to start the
vacuum (allow a few seconds for vacuum to
build in the bleeder reservoir before suction oc­curs). While evacuating the old fluid, stir it up to
break loose and remove any sludge that has ac­cumulated on the bottom and walls of the master
cylinder.

7. Once all fluid is removed, turn off the bleeder
and refill the master cylinder with new manufac
turer’s recommended brake fluid.

Vacuum bleed brake lines and wheel
brake cylinders

Note: Prior to bleeding, ensure the master cylinder

is full of new manufacture’s recommended brake
fluid. An automatic master cylinder refill kit is
included with the vacuum bleeder to maintain the
level of new fluid in the master cylinder during the
brake bleeding process. Follow the instructions in­cluded with the kit to prevent air from being sucked
into the master cylinder pistons, brake lines, and
wheel cylinders while bleeding the brakes. Addi­tional automatic refill kits are available from Mity­vac.

1. Properly position the vehicle for safe convenient
access to the brake bleed screw located on
each wheel brake cylinder.

2. Make sure that all bleed screws are clean.

indicate a malfunction. To prevent or reduce this
introduction of air, coat the bleed screw threads
with silicon grease prior to bleeding.

7. Keep the bleed screw open until new fluid is
visibly flowing through the bleed tube (typically
20 to 30 seconds).

8. Close the bleed screw firmly, without over tight
ening, prior to removing the bleed screw adapter
or shutting off the bleeder.

Note: It is important to ensure that the bleed

screw adapter remains connected to the bleed
screw, and the bleeder is still pulling a vacuum
while the bleed screw is closed. This prevents
air from being sucked back into the wheel cylin­der from around the bleed screw threads, before
the bleed screw is tightened and sealed.

3. Connect clean, regulated (60 psi (4.1 bar) to
150 psi (10.3)) compressed air to the male quick
disconnect nipple attached to the swivel air
inlet, located on one end of the vacuum bleeder
handle.

4. Connect the appropriate end of the bleed tube
assembly to the female quick disconnect cou­pler located on top of the vacuum bleeder.

Note: Consult the vehicle manufacturer’s guide-

lines for the proper wheel bleeding sequence
and vacuum bleeding procedure.

5. Slip the bleed screw adapter located on the op
posite end of the bleed tube assembly, over the
nipple of the bleed screw.

6. Operate the vacuum bleeder by pushing the
throttle forward (allow a few seconds for vacu­um to build in the bleeder reservoir before suc­tion occurs), and with the appropriate wrench,
loosen/open the bleed screw slightly, until fluid
is visibly draining through the bleed hose and
into the reservoir.

Note: During the bleeding process, as brake

fluid is being vacuumed through the bleed
screw, air will also be sucked into the bleed tube
from around the bleed screw threads. This can
give the misconception that air is bleeding from
the lines, however it is normal and does not

Note: If an automatic refiller such as the one

provided with this unit, is not used, be sure to
periodically check the level and top off the brake
fluid in the master cylinder.

Instructions for bleeding hydraulic

clutch system

IMPORTANT: This unit is designed for servicing a

variety of vehicles in a safe, convenient manner.
However, hydraulic clutch systems vary between
vehicles, in design, in components, and even the
location and design of the bleed screw. Due to
these differences, the following procedures are to
