Bleeding Brakes
Instructions for Setup:
1. Select the brake bleeding hose and connect one end to the in-line fluid shut off valve. Connect the
main connector to the reservoir tank and the universal bleeding elbow to the bleeder screw.
2. Close the in-line fluid shut off valve (handle of valve will be turned 90 degrees from hose).
3. Connect air hose to the Venturi at the base of the PneumatiVac. This will require a male 3/4" NPT
fitting that is used with your system (not included).
4. Open the air shut off valve thereby creating a vacuum inside the reservoir tank that will be used to
bleed the brakes.
The following brake bleeding procedure is recommended:
1. Ensure master cylinder reservoir is full of the specified fluid and new dean fluid is available to top
off reservoir during bleeding procedure. Ensure all bleeder fittings are clean at the start of bleeding
procedure.
2. Bleed system in the following order:
a. Master cylinder (if necessary). See the Bench Bleeding Procedure below if a new or rebuilt master
cylinder is being installed.
b. ABS controller (if necessary).
c. Wheel cylinders and calipers in succession beginning with the wheel closest to the master cylinder
and working to the farthest one.
3. Place wrench on the nut of the bleeder screw.
4. Connect brake bleeding adapter onto bleeder screw.
5. Open the air shut off valve by turning it to the "OPEN" position, thereby creating a vacuum required for
bleeding.
6. Open the bleeder screw slightly, only enough to cause fluid to flow into the bleeder hose and continue
into the PneumatiVac™ (usually 1/4 to 1/2 turn).
7. After evacuating, approximately 1/4 of the master cylinder reservoir capacity, tighten the bleeder
screw. Add new brake fluid to the master cylinder so it remains full then proceed to the next wheel.
NOTE: A tiny stream of bubbles may be noted in the bleeder hose after the bleeding procedure. This is
caused by air seeping around the threads of the loosened bleeder screw and is drawn through
the fitting by the suction created by the Fluid Evacuator. Once the air has been removed from
the system, these tine air bubbles DO NOT jeopardize the bleeding operation since they are only
present at the external surface of the floeder fitting and not in the system. If desired, bleeder
fitting threads may be sealed with Teflon
NOTE: When finished using the PneumatiVac, contents should be emptied into an approved waste
container. Rinse reservoir with water, or solvent where applicable.
