STANDARD PROCEDURE
BASE BRAKE BLEEDING
NOTE: For bleeding the ABS hydraulic system, refer to Antilock Brake System Bleeding in the Antilock
Brake System section.
5 - 6
BRAKES - BASE
PM
CAUTION: Before removing the master cylinder cap, wipe it clean to prevent dirt and other foreign matter
from dropping into the master cylinder reservoir.
CAUTION: Use only Mopar
T
brake fluid or an equivalent from a fresh, tightly sealed container. Brake fluid
must conform to DOT 3 specifications.
NOTE: For bleeding of the Antilock Brake System, (Refer to 5 - BRAKES - ABS - STANDARD PROCEDURE).
Do not pump the brake pedal at any time while having a bleeder screw open during the bleeding process. This will
only increase the amount of air in the system and make additional bleeding necessary.
Do not allow the master cylinder reservoir to run out of brake fluid while bleeding the system. An empty reservoir will
allow additional air into the brake system. Check the fluid level frequently and add fluid as needed.
The following wheel circuit sequence for bleeding the brake hydraulic system should be used to ensure adequate
removal of all trapped air from the hydraulic system.
•
Left rear wheel
•
Right front wheel
•
Right rear wheel
•
Left front wheel
MANUAL BLEEDING
NOTE: To bleed the brakes manually, the aid of a helper will be required.
1. Attach a clear plastic hose (1) to the bleeder screw
and feed the hose into a clear jar (2) containing
enough fresh brake fluid to submerge the end of
the hose.
2. Have a helper pump the brake pedal three or four
times and hold it in the down position.
3. With the pedal in the down position, open the
bleeder screw at least one full turn.
4. Once the brake pedal has dropped, close the
bleeder screw. After the bleeder screw is closed,
release the brake pedal.
5. Repeat the above steps until all trapped air is
removed from that wheel circuit (usually four or five
times).
PM
BRAKES - BASE
5 - 7
6. Bleed the remaining wheel circuits in the same
manner until all air is removed from the brake sys-
tem. Monitor the fluid level in the master cylinder
reservoir (2) to make sure it does not go dry.
7. Check and adjust brake fluid level to the FULL
mark.
8. Check the brake pedal travel. If pedal travel is
excessive or has not been improved, some air may
still be trapped in the system. Re-bleed the brakes
as necessary.
9. Test drive the vehicle to verify the brakes are oper-
ating properly and pedal feel is correct.
PRESSURE BLEEDING
NOTE: Follow pressure bleeder manufacturer’s instructions for use of pressure bleeding equipment.
Following the same wheel circuit sequence as prescribed for manual bleeding.
1. Attach Master Cylinder Cap (2), Special Tool 6921,
in place of the filler cap on the master cylinder res-
ervoir (3).
2. Attach Bleeder Tank (1), Special Tool C-3496-B, or
an equivalent, to the Master Cylinder Cap 6921.
