13. Submerge the open end of the transparent hose into a transparent container partially filled with Delco Supreme 11(R), GM P/N 12377967
(Canadian P/N 992667), or equivalent DOT-3 brake fluid from a clean, sealed brake fluid container.
14. Loosen the bleeder valve to purge air from the wheel hydraulic circuit. Allow fluid to flow until air bubbles stop flowing from the bleeder, then
tighten the bleeder valve.
15. With the right rear wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right rear hydraulic circuit,
install a proper box-end wrench onto the LEFT FRONT wheel hydraulic circuit bleeder valve.
16. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14.
17. With the left front wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the left front hydraulic circuit, install
a proper box-end wrench onto the LEFT REAR wheel hydraulic circuit bleeder valve.
18. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14.
19. With the left rear wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the left rear hydraulic circuit, install a
proper box-end wrench onto the RIGHT FRONT wheel hydraulic circuit bleeder valve
20. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14.
21. After completing the final wheel hydraulic circuit bleeding procedure, ensure that each of the 4 wheel hydraulic circuit bleeder valves are properly
tightened.
22. Close the J29532, or equivalent, fluid tank valve, then disconnect the J29532, or equivalent, from the J35589-A.
23. Remove the J35589-A from the brake master cylinder reservoir.
24. Fill the brake master cylinder reservoir to the maximum-fill level with Delco Supreme 11(R), GM P/N 12377967 (Canadian P/N 992667), or
equivalent DOT-3 brake fluid from a clean, sealed brake fluid container.
25. Slowly depress and release the brake pedal. Observe the feel of the brake pedal.
26. If the brake pedal feels spongy, perform the following steps:
Important: If it is determined that air was induced into the system upstream of the ABS modulator prior to servicing, the ABS Automated Bleed
Procedure must be performed.
1. Inspect the brake system for external leaks.
2. Using a scan tool, perform the antilock brake system automated bleeding procedure to remove any air that may have been trapped in the
BPMV.
27. Turn the ignition key ON, with the engine OFF. Check to see if the brake system warning lamp remains illuminated.
28. If the brake system warning lamp remains illuminated, refer to Symptoms - Hydraulic Brakes. See: Testing and Inspection/Symptom Related
Diagnostic Procedures
Important: DO NOT allow the vehicle to be driven until it is diagnosed and repaired.
