Brake bleeder and vacuum pump kit
Setup Instructions
1. Open the Cup (3).
2. Seat the O-ring (11) completely into the groove in the top of the Cup.
3. Remove the shipping spacer that prevents the Vacuum Pump (1) handle
from moving through its full range.
4. Cover the inlet of the Vacuum Pump with something such as a plastic bag.
To prevent injury, DO NOT USE YOUR SKIN TO PLUG THE INLET. Operate the pump several times to create the vacuum. The vacuum should not decrease quickly. If air
is entering through the vacuum release valve, tighten it. After the pump properly holds a vacuum, press in the Pump’s vacuum release valve to release the vacuum. Set the plastic bag aside.
5. The vacuum pump should now be ready for use.
Vacuum System Testing
1. Position the vehicle in a flat, level outdoor area. Set the parking brake and chock the tires.
2. Attach a 23" Hose (4) to the Vacuum Pump (1).
3. Attach the other end of the Hose to the vacuum system. Keep clear of parts that will move or get hot while an assistant starts the engine. Wait until the vacuum reading
stabilizes and compare it to the manufacturer’s specification.
4. After obtaining a measurement, shut off the engine.
5. A low or unstable vacuum reading may mean a vacuum leak, vacuum line blockage, cylinder sealing problems, incorrect valve/ignition timing, or other issues.
Note: Vehicle vacuum systems will differ. Consult the vehicle’s service manual for proper testing procedures.
6. After testing is complete, disconnect the Vacuum Pump and Hose, remove any plugs or clamps and secure all vacuum lines
Brake Bleeding
1. Attach a 3" Hose (5) to the bottom of the Suction Lid (2a).
2. Attach a 23" Hose (4) to the port on the top of the Suction Lid that does not have the 3" Hose attached, as shown in Figure A. Then, attach the other end of that 23" Hose to the Vacuum Pump (1).
3. Make sure the O-ring (11) is completely seated into the groove on the top of the Cup to provide a good seal. Firmly attach the Suction Lid to the Cup (3).
4. Remove the cap from the vehicle’s master cylinder, and make sure the master cylinder is full of brake fluid. If not full, fill the master cylinder to capacity with clean, new
brake fluid. (Use only the kind of brake fluid recommended by the vehicle manufacturer.)
Note: Determine the proper brake bleeding sequence from your vehicle service manual (i.e., right rear wheel, left rear wheel, right front wheel, left front wheel).
5. Connect the 23" Hose (4) to the remaining port on the Suction Lid.
6. Insert the Tapered Hose Adapter (6) into the 23" Hose. Connect the other end of the adapter to the Brake Bleed Screw Adapter (9).
7. Squeeze the Handle of the Vacuum Pump 10 to 15 times to create a vacuum in the Cup.
Note: The Gauge on the Vacuum Pump should read at approximately 10 inHg. Do not exceed 20 inHg. A greater vacuum could damage the vehicle’s brake system.
8. Open the vehicle’s brake caliper bleed screw, and allow brake fluid to flow into the Cup until fluid appears clear and free of bubbles. Then, retighten the bleed screw.
