Pressure Bleeding Method

WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Follow pressure bleeder manufacturer's instructions for use of pressure bleeding equipment.

  1. Remove filler cap from the top of fluid reservoir (2) on master cylinder.
  2. Install Adapter (1), Special Tool 6921, in the caps place on the reservoir (2).
  3. Attach Bleeder Tank, Special Tool C-3496-B, or equivalent, to Adapter 6921 (1). Pressurize the system following the pressure bleeder manufacturer's instructions.

    NOTE: To ensure all air is bled from the ICU or junction block in a timely manner, it is recommended to raise the rear of the vehicle approximately 5° higher than the front or approximately 10-12 inches as measured at the rear bumper (1).
  4. Raise and support vehicle placing rear of vehicle approximately 5° higher than the front or if measured at the rear bumper (1), approximately 10-12 inches above level. It will be necessary to add extra support stands under vehicle to support this angle.

  5. If installed, remove rubber dust caps from all four bleeder screws on calipers.
  6. Starting at the first wheel circuit as listed earlier, attach a clear hose (1) to the bleeder screw at that wheels brake caliper and feed the other end of hose into a clear jar (2) containing enough fresh brake fluid to submerge the end of the hose.
    CAUTION: Open the bleeder screw at least one full turn when instructed. Some air may be trapped in the brake lines or valves far upstream, as far as ten feet or more from the bleeder screw. If the bleeder screw is not opened sufficiently, fluid flow is restricted causing a slow, weak fluid discharge. This will NOT get all the air out. Therefore, it is essential to open the bleeder screw at least one full turn to allow a fast, large volume discharge of brake fluid.
  7. Open bleeder screw at least one full turn or more to obtain an adequate flow of brake fluid.
  8. After 4 to 8 ounces of brake fluid has been bled through the brake hydraulic circuit, and an air-free flow (no bubbles) is maintained in the clear plastic hose (1) and jar (2), close the bleeder screw.
  9. Bleed the remaining wheel circuits in the same manner until all air is removed from the brake hydraulic system.
  10. Check brake pedal travel. If pedal travel is excessive or has not improved, some air may still be trapped in the hydraulic system. Rebleed the brake system as necessary.
  11. If equipped with antilock brakes, the hydraulic control unit may need to be bled, then rebleed base brakes. See Brakes - Standard Procedure 
  12. Reinstall all 4 bleeder screw dust caps.
  13. Test drive vehicle to ensure brakes are operating properly and pedal feel is correct.
