CTS RWD V6-3.6L (2008)
Any brake fluid leaks identified require repair prior to completing this procedure.
11. Install a proper box-end wrench onto the RIGHT REAR wheel hydraulic circuit, inboard (CTS-V), bleeder valve.
12. Install a transparent hose over the end of the bleeder valve.
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. For CTS-V models, repeat steps 11-14 for the outboard bleeder valve.
16. With the right rear wheel hydraulic circuit bleeder valve, or valves (CTS-V), 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, inboard (CTS-V), bleeder valve.
17. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14.
18. For CTS-V models, repeat steps 11-14 for the outboard bleeder valve.
19. With the left front wheel hydraulic circuit bleeder valve, or valves (CTS-V), 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, inner (CTS-V), bleeder valve.
20. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14.
21. For CTS-V models, repeat steps 11-14 for the outboard bleeder valve.
22. With the left rear wheel hydraulic circuit bleeder valve, or valves (CTS-V), 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, inner (CTS-V), bleeder valve.
23. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14.
24. For CTS-V models, repeat steps 11-14 for the outboard bleeder valve.
25. After completing the final wheel hydraulic circuit bleeding procedure, ensure that each of the 4 wheel hydraulic circuit bleeder valves, or 8 bleeder
valves (CTS-V), are properly tightened.
26. Close the J 29532 , or equivalent, fluid tank valve, then disconnect the J 29532 , or equivalent, from the J 35589-A .
27. Remove the J 35589-A from the brake master cylinder reservoir.
28. 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.
29. Slowly depress and release the brake pedal. Observe the feel of the brake pedal.
30. If the brake pedal feels spongy perform the following steps:
1. Inspect the brake system for external leaks. Refer to Brake System External Leak Inspection (See: Hydraulic System/Testing and
Inspection/Component Tests and General Diagnostics/Brake System External Leak Inspection) .
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. Refer to Antilock Brake System Automated Bleed Procedure (See: ) .
31. Turn the ignition key ON, with the engine OFF. Check to see if the brake system warning lamp remains illuminated.
Important: DO NOT allow the vehicle to be driven until it is diagnosed and repaired.
32. If the brake system warning lamp remains illuminated. Refer to Symptoms - Hydraulic Brakes (See: Hydraulic System/Testing and
Inspection/Symptom Related Diagnostic Procedures/Symptoms - Hydraulic Brakes) .
