Pressure Bleeding
NOTE:
Pressure bleed the brake system at 345 kPa (50 psi).
- Clean all dill from and remove the brake master cylinder filler cap and fill the brake master cylinder reservoir with the specified brake fluid.
- Install the bleeder adapter to the brake master cylinder reservoir, and attach the bleeder tank hose to the fitting on the adapter.
- Refill the brake master cylinder reservoir, as necessary.
- Place a box end wrench on the bleeder screw. Attach a rubber drain tube to the bleeder screw, and submerge the free end of the tube in a container partially filled with clean brake fluid.
- Open the valve on the bleeder tank.
- Loosen the bleeder screw. Leave open until clear, bubble-free brake fluid flows. Have an assistant pump the brake pedal once every 2 seconds after the scan tool runs the HCU pump. Wait 15 seconds after clear, bubble-free fluid flows through the rubber hose. Then, tighten the bleeder screw and remove the rubber hose.
- Continue bleeding the rear of the system repeating Step 4 and 5.
- Close the bleeder tank valve. Remove the tank hose from the adapter, and remove the adapter.
- Install a new reservoir cap.
NOTE:
Master cylinder pressure bleeder adapter tools are available from various manufacturers of pressure bleeding equipment. Follow the instructions of the manufacturer when installing the adapter.
NOTE:
Bleed from the longest to the shortest brake line. Make sure the bleeder tank contains enough specified brake fluid to complete the bleeding operation.
