Antilock Brake System Automated Bleed Procedure: Notes

WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.

Special Tools

J 29532 Diaphragm Pressure Bleeder, or J-29532-A Brake Pressure Bleeder, or equivalent. See Special Tools .
J 35589-A Brake Bleeder Adapter, or equivalent. See Special Tools .

CAUTION: At times during this brake bleed procedure brake fluid will be under higher pressures than during typical brake bleed procedures. Ensure the bleeder hose attached to the bleeder valve is securely maintained in position whenever the bleeder valve is opened. Failure to maintain the bleeder hose securely to the valve when opened, may allow the hose to blow off and brake fluid to spray out of the bleeder valve, possibly resulting in personal injury.

NOTE: When adding fluid to the brake master cylinder reservoir, use only Delco Supreme 11®, GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT-3 brake fluid from a clean, sealed brake fluid container. The use of any type of fluid other than the recommended type of brake fluid, may cause contamination which could result in damage to the internal rubber seals and/or rubber linings of hydraulic brake system components.

NOTE: Refer to Brake Fluid Effects on Paint and Electrical Components Notice .

IMPORTANT:

Do not pressurize the brake pressure bleeder J-29532-A or J 29532 and thereby the master cylinder reservoir until instructed to do so by the scan tool. See Special Tools . Portions of the automated bleed process require the master cylinder reservoir not be pressurized through the J-29532-A or J 29532 . See Special Tools .
Do not apply the brake pedal until instructed to do so by the scan tool. Applying the brake pedal before instructed by the scan tool may result in setting a DTC and may require the sensor and boost valve calibration and electronic brake control module (EBCM) learn procedures to be repeated manually.
