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 oc-
curs). While evacuating the old fluid, stir it up to
break loose and remove any sludge that has ac-
cumulated 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 clutch master cylinder,
slave cylinder, and hydraulic lines
Note: Prior to bleeding, ensure the master cyl-
inder 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 clutch bleeding process. Follow the instruc-
tions included with the kit to prevent air from being
introduced into the master cylinder pistons, slave
cylinder, and fluid lines while bleeding the hydraulic
clutch system. Additional automatic refill kits are
available from Mityvac.
1. Properly position the vehicle for safe convenient
access to the clutch bleed screw located on the
slave cylinder.
2. Make sure that the slave cylinderbleed screw is
clean.
3. 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.

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 guide-
lines for the proper clutch vacuum bleeding
procedure.
5. Slip the universal 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 vacuum
to build in the bleeder reservoir before suction
occurs), and with the appropriate wrench, loos-
en/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 bleeder
hose 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 hose.
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 slave cylin-
der 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.
