W/ Rear Wheel Antilock Brakes
GENERAL INFORMATIONRWAL brake bleeding can be performed manually, or with pressure bleeding equipment.
Use Mopar DOT 3 brake fluid, or an equivalent meeting SAE J1703-F and DOT 3 standards, to fill and bleed the brake system.
Bleed only one brake component at a time. Recommended bleed sequence is:
- master cylinder
- combination valve
- rear antilock valve
- left rear wheel
- right rear wheel
- right front wheel
- left front wheel
MANUAL BLEEDING
Use a bleed hose at each caliper/cylinder bleed screw. Attach one end of the hose to the bleed screw and insert the opposite end in glass container partially filled with brake fluid. A glass container makes it easier to see air bubbles as they exit the bleed hose. Be sure the end of the bleed hose remains immersed in fluid. This prevents air from being drawn back into the system.
Do not allow the master cylinder to run out of fluid when bleeding the brakes. An empty cylinder will allow air to be drawn back into the system. Check fluid level frequently during bleeding operations.
Be sure to tighten each brake line fitting, or bleed screw once bleeding is completed. Loose fittings and bleed screws allows air to enter the system.
PRESSURE BLEEDING
If pressure bleeding equipment will be used, the front brake metering valve will have to be held open to bleed the front brakes. The valve stem is located in the forward end of the combination valve. The stem must either be pressed inward, or held outward slightly. a spring clip tool or helper is needed to hold the valve stem in position.
Follow the manufacturers instructions carefully when using pressure equipment. Do not exceed the tank manufacturers pressure recommendations. Generally, a tank pressure of 15 - 20 psi is sufficient for bleeding.
Fill the bleeder tank with recommended fluid and purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder adapter. The wrong adapter can lead to leakage, or drawing air back into the system.
