Pressure Bleeding


Use bleeder tank Special Tool C-3496-B or equivalent with Adapter, Special Tool 6921, to pressurize the hydraulic system for bleeding.

Follow pressure bleeder manufacturer's instructions for use of pressure bleeding equipment.

  1. Install the Adapter Master Cylinder Pressure Bleed Cap, tool 6921, on the master cylinder fluid reservoir. Attach the fluid hose from the pressure bleeder to the fitting on tool 6921.

  3. Attach a clear plastic hose to the bleeder screw at one wheel and feed the hose into a clear jar containing enough fresh brake fluid to submerge the end of the hose.
  5. Open the left rear wheel bleeder screw at least one full turn or more to obtain an adequate flow of brake fluid.
    -Just cracking- the bleeder screw often restricts fluid flow, allowing only a slow, weak fluid discharge of fluid. This practice will NOT get all the air out. Make sure the bleeder is opened at least 1 full turn when bleeding.

  7. After approximately four to eight ounces of brake fluid has been bled through the hydraulic system, and an air-free flow is maintained in the hose and jar, close the bleeder screw.
  9. Repeat the procedure at all the remaining bleeder screws.
  11. Check and adjust brake fluid level to the FULL mark on the reservoir.
  13. Check pedal 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. Re-bleed the brakes as necessary. Be sure to monitor the fluid level in the pressure bleeder, to ensure that it stays at a proper level so air will not enter the brake system through the master cylinder.
  15. Test drive vehicle to be sure brakes are operating correctly and that pedal is solid.
