Bleeding the Brake System

Print

Tools Required:



J 29532 Diaphragm Pressure Bleeder
 
J 39801-VIBE Pressure Bleeder Adapter
 


CAUTION
 Do not move the vehicle until a firm brake pedal is obtained. Air in the brake system can cause the loss of brakes with possible personal injury.


CAUTION
Remove all the air from the hydraulic brake system anytime the hydraulic brake system is opened for repair. The entire bleeding procedure must be followed. Failure to remove all the air in the hydraulic brake system will result in reduced braking performance and possible personal injury.


CAUTION
Brake fluid may irritate eyes and skin. In case of contact, take the following actions:



Eye contact--rinse thoroughly with water.
 
Skin contact--wash with soap and water.
 
If ingested--consult a physician immediately.
 


CAUTION
Caution: Use only Delco Supreme 11, GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT 3 brake fluid from a clean, sealed container. Do not use fluid from an open container that may be contaminated with water. Improper or contaminated fluid could result in damage to components, or loss of braking, with possible injury.


NOTE
 When filling the master cylinder, use only Delco Supreme 11, GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT 3 brake fluid. Do not use a container which has been used for petroleum based fluids, or a container which is wet with water. Petroleum based fluids will cause swelling and distortion of rubber parts in the hydraulic brake system, and water will mix with brake fluid, lowering the boiling point. Keep all fluid containers capped to prevent contamination.


NOTE
Avoid spilling brake fluid onto painted surfaces, electrical connections, wiring, or cables. Brake fluid will damage painted surfaces and cause corrosion to electrical components. If any brake fluid comes in contact with painted surfaces, immediately flush the area with water. If any brake fluid comes in contact with electrical connections, wiring, or cables, use a clean shop cloth to wipe away the fluid.

  1. Bleed the hydraulic brake system in the following sequence:
    1. The master cylinder
    2.  
    3. Right rear bleeder valve
    4.  
    5. Left rear bleeder valve
    6.  
    7. Right front bleeder valve
    8.  
    9. Left front bleeder valve
    10.  

  2.  

If air enters the hydraulic brake system due to low brake fluid level, bleed the system at the master cylinder and at the 4 bleeder valves.

If you disconnect a brake pipe from the master cylinder, bleed the system at the master cylinder and at the 4 bleeder valves.

If you disconnect a brake pipe or a fitting between the master cylinder and the wheels, bleed the system at the bleeder valve served by the brake pipe or fitting.

If you disconnect a brake pipe or brake hose at only 1 wheel, bleed the system at the bleeder valve for that wheel.
