9. Wait approximately 30 seconds, then inspect the entire hydraulic brake system in order to ensure that there are no existing external brake fluid leaks. Any brake fluid leaks identified require repair prior to completing this procedure. 10. Install a proper box-end wrench onto the RIGHT REAR wheel hydraulic circuit bleeder valve. 11. Install a transparent hose over the end of the bleeder valve. 12. Submerge the open end of the transparent hose into a transparent container partially filled with brake and clutch fluid Super Dot-4, GM P/N 88958860 (Canadian P/N 88901244) or 13. 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. 14. 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 15. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14. 16. 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 17. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14. 18. With the right front wheel hydraulic circuit bleeder valve tightened securely, after all air has been purged from the right front hydraulic circuit, install a proper box-end wrench onto the 19. Install a transparent hose over the end of the bleeder valve, then repeat steps 13-14. 20. After completing the final wheel hydraulic circuit bleeding procedure, ensure that each of the 4 wheel hydraulic circuit bleeder valves are properly tightened. 21. Close the J 29532 or equivalent, fluid tank valve, then disconnect the J 29532 or equivalent, from the J 44894-A . See Special Tools. 22. Remove the J 44894-A from the brake master cylinder reservoir. See Special Tools. 23. Fill the brake master cylinder reservoir. Refer to Master Cylinder Reservoir Filling. 24. Slowly depress and release the brake pedal. Observe the feel of the brake pedal. 25. 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 . 2. Using a scan tool, perform the antilock brake system automated bleeding procedure to
