Brake Bleeding: Service and Repair
Pressure Bleeding
WARNING: BRAKE FLUID CONTAINS POLYGLYCOL ETHERS AND POLYGLYCOLS. AVOID CONTACT WITH EYES. WASH
HANDS THOROUGHLY AFTER HANDLING. IF BRAKE FLUID CONTACTS EYES, FLUSH EYES WITH RUNNING WATER FOR 15
MINUTES. GET MEDICAL ATTENTION IF IRRITATION PERSISTS. IF TAKEN INTERNALLY, DRINK WATER AND INDUCE
VOMITING. GET MEDICAL ATTENTION IMMEDIATELY.
CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with
water.
NOTES:

Refer To Specifications for proper brake fluid requirements.

Review Service Precautions before begining procedures. See: Hydraulic System/Service Precautions
DESCRIPTION
^
Bleed the longest tubes first on the system being bled.
^
The bleeder tank should contain enough new brake fluid to complete the bleeding operation.
^
Use DOT-3 motor vehicle brake fluid. Never reuse brake fluid that has been drained from the hydraulic system. The pressure bleeder tank should
be charged with approximately 69-206 kPa (10 to 30 psi) of air pressure.
PROCEDURES
1. Clean all dirt from the brake master cylinder filler cap.
CAUTION: The pressure bleeder tank should be charged with approximately 69-206 kPa (10 to 30 psi) of air pressure. To prevent system
damage, NEVER exceed 344 kPa (50 psi) pressure.
2. Remove the brake master cylinder filler cap. Fill the brake master cylinder reservoir with the specified brake fluid. Install the pressure bleeder
adapter tool to the brake master cylinder and attach the bleeder tank hose to the fitting on the adapter. Follow the instructions of the manufacturer
to install the adapter.
3. Bleed brake master cylinder as described. See: Master Cylinder Bleeding
4. If the rear disc brake calipers are to be bled, start with LH rear disc brake caliper and attach bleed tube snugly around wheel cylinder bleeder
screw fitting.
5. Open the valve on the bleeder tank to admit pressurized brake fluid into the brake master cylinder reservoir.
6. Submerge the free end of the tube in a container partially filled with clean brake fluid and loosen the wheel cylinder bleeder screw.
7. When air bubbles cease to appear in the fluid at the submerged end of the bleeder tube, close the wheel cylinder bleeder screw. Remove the tube.
Replace rubber dust cap on bleeder screw.
8. Repeat Steps 3 through 6 at RH rear disc brake caliper.
9. Attach a bleed tube to front brake caliper wheel cylinder bleeder screws and repeat Steps 4 through 6, starting at the caliper with the longest brake
tube and ending with the shortest tube.
10. After all calipers have been bled, bleed the brake master cylinder using bleed screws on brake master cylinder.
11. When the bleeding operation is completed, close the bleeder tank valve and remove the tank hose from the adapter fitting.
12. After disc brake service, make sure disc brake pistons are returned to their normal positions and the shoe and lining assemblies are properly seated.
This is accomplished by depressing the brake pedal several times until normal pedal travel is established.
13. Remove the pressure bleeder adapter tool from brake master cylinder. Fill the brake master cylinder reservoir. Install the brake master cylinder
filler cap.
14. Retest vehicle.
