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.
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.
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 cou-
pler located on top of the vacuum bleeder.
Note: Consult the vehicle manufacturer's
guidelines for the proper wheel bleeding se-
quence and vacuum bleeding procedure.
5. Slip the bleed screw adapter located on the
opposite 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 vacu-
um 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

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
tightening, 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.
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
serve only as a guideline for the use of this equip-
ment. In addition to these guidelines, always follow
the manufacturer's recommended procedures
when servicing each unique vehicle.
Removing old fluid from the clutch 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
reservoir.
