WARNING:
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.
CAUTION:
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.
CAUTION:
Refer to Brake Fluid Effects on Paint and Electrical Components Caution

NOTE:
- Do not pressurize the brake pressure bleeder CH-29532-A: Brake Pressure Bleeder and thereby the master cylinder reservoir until instructed to do so by the scan tool. Portions of the automated bleed process require the master cylinder reservoir not be pressurized through the CH-29532-A: Brake Pressure Bleeder.
- 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.
