Brake Bleeding: Service and Repair
Base Brake System
OVERVIEW
A new master cylinder should be bled before installation on the vehicle. Required bleeding tools include bleed tubes and a wood dowel to stroke the
pistons. Bleed tubes can be fabricated from brake line.
BLEEDING PROCEDURE
1. Mount master cylinder in vise.
2. Attach bleed tubes to cylinder outlet ports. Then position each tube end into reservoir.
3. Fill reservoir with fresh brake fluid.
4. Press cylinder pistons inward with wood dowel. Then release pistons and allow them to return under spring pressure. Continue bleeding operations
until air bubbles are no longer visible in fluid.
BASE BRAKE BLEEDING
Use Mopar 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 pump the brake pedal at any time while bleeding. Air in the system will be compressed into small bubbles that are distributed throughout the
hydraulic system. This will make additional bleeding operations necessary.
Do not allow the master cylinder to run out of fluid during bleed operations. An empty cylinder will allow additional air to be drawn into 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:
^
Master Cylinder
^
Combination Valve
^
Rear Antilock Valve
^
Right Rear Wheel
^
Left Rear Wheel
^
Right Front Wheel
^
Left Front Wheel
MANUAL BLEEDING
1. Remove reservoir filler caps and fill reservoir.
2. If calipers, or wheel cylinders were overhauled, open all caliper and wheel cylinder bleed screws. Then close each bleed screw as fluid starts to
drip from it. Top off master cylinder reservoir once more before proceeding.
