Manual Brake Bleeding

MANUAL BLEEDING

NOTE: Do not use this procedure if the master cylinder, Hydraulic Control Unit (HCU), brake booster, or the lines between the master cylinder and the HCU have been replaced. If any of these components are replaced perform the Pressure Bleeding procedure Service and Repair .

Use Mopar(R) brake fluid, or an equivalent quality fluid meeting SAE J1703-F and DOT 3 standards only. Use fresh, clean fluid from a sealed container at all times.

Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to enter the system. Check the cylinder fluid level frequently and add fluid as needed.





Bleed only one brake component at a time in the following sequence:

1. Fill the master cylinder reservoir with brake fluid.
2. If the calipers are overhauled, open the caliper bleed screws. Then close each bleed screw as fluid starts to drip from it. Top off the master cylinder reservoir once more before proceeding.
3. Attach one end of the bleed hose (1) to the bleed screw and insert the opposite end in a suitable container (2) partially filled with brake fluid. Be sure the end of the bleed hose is immersed in fluid.
4. Open up the bleeder screw, then have a helper press down the brake pedal. Once the pedal is down close the bleeder screw. Repeat bleeding until the fluid stream is clear and free of bubbles. Then move to the next wheel.
