Brake Bleeding: Service and Repair
Base Brake System Bleeding
On models with power brakes, if bleeding the hydraulic system without the engine running, first reduce vacuum in the power unit to zero by pumping the
brake pedal several times with the engine off.
1.
Ensure master cylinder reservoir is full. Add suitable brake fluid as needed, and securely reinstall the master cylinder cap.
2.
Raise and support vehicle.
3.
Position a drain pan under the wheel being bled. Refer to Brakes and Traction Control/Brakes/Specifications/Mechanical for proper wheel
bleeding sequence.
4.
Have an assistant depress the brake pedal with a slow even pressure and hold it. Do not depress brake pedal fully to the end of the master
cylinder stroke. This may cause damage to the master cylinder.
5.
Using a suitable wrench, open the bleeder valve one full turn. Watch for air bubbles in the fluid, and listen for air escaping from the system.
6.
With the brake pedal still depressed, close the bleeder valve.
7.
Have the assistant pump the brake pedal several times. Do not depress brake pedal fully to the end of the master cylinder stroke, this may
cause damage to the master cylinder.
8.
Repeat steps 4 through 7 following the wheel bleeding sequence specified in SPECIFICATIONS/MECHANICAL
SPECIFICATIONS/HYDRAULIC BRAKE SYSTEM SPECIFICATIONS. Ensure all air is removed from the hydraulic system. While
bleeding the system, recheck brake fluid supply in the master cylinder often so as not to allow the master cylinder to run dry.
9.
Upon completion of hydraulic system bleeding proceed as follows:
a. Ensure the master cylinder reservoir is full. Add suitable brake fluid as needed, and securely reinstall the master cylinder cap.
b. Lower the vehicle. Ensure brake pedal is firm and braking operation is proper.
