Pressure Bleeding (Preferred Procedure)

Air Trapped In Brake System:

Method For Purging Air From Brake System:

Bleeder Screw:

CAUTION:
- Before removing the Master Cylinder cover, wipe it clean to prevent dirt and other foreign matter from dropping into the master cylinder.
- Use bleeder tank Special Tool C-3496-B, or equivalent with required adapter for the master cylinder reservoir to pressurize the hydraulic system for bleeding.

NOTE:
- For bleeding the ABS hydraulic system, refer to Hydraulic Control Unit.
- Follow pressure bleeder manufacturer's instructions for use of pressure bleeding equipment.

PROCEDURE
When bleeding the brake system, some air may be trapped in the brake lines or valves far upstream, as much as ten feet from the bleeder screw. Therefore, it is essential to have a fast flow of a large volume of brake fluid when bleeding the brakes to ensure all the air gets out. The following wheel sequence for bleeding the brake hydraulic system should be used to ensure adequate removal of all trapped air from the hydraulic system.

^ Left rear wheel
^ Right front wheel
^ Right rear wheel
^ Left front wheel

1. Attach a clear plastic hose to the bleeder screw starting at the right rear wheel and feed the hose into a clear jar containing enough fresh brake fluid to submerge the end of the hose.
2. Open the bleeder screw at least one full turn or more to obtain an steady stream of brake fluid.
3. After 4 to 8 ounces of fluid has been bled through the brake and an air-free flow is maintained in the clear plastic hose and jar, close the bleeder screw.
4. Repeat the procedure at all the other remaining bleeder screws. Then check the pedal for travel. If pedal travel is excessive or has not been improved, enough fluid has not passed through the system to expel all the trapped air. Be sure to monitor the fluid level in the pressure bleeder. It must stay at the proper level so air will not be allowed to reenter the brake system through the master cylinder reservoir.
