- Install the lubricated seals, make sure that the seals are fully seated in the brake master cylinder. Lubricate the new seals and the outer surface area of the reservoir-to-housing barrels 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. Install the lubricated seals. Ensure that they are fully seated.
- Install the reservoir to the master cylinder by pressing the reservoir straight down on the master cylinder until the pin holes are aligned.
- Carefully install the reservoir retaining pins to secure the reservoir. Place the brake fluid level sensor into the reservoir, press into place to secure the sensor retaining tabs, if applicable.
- Remove the master cylinder from the vice. Install the master cylinder. See MASTER CYLINDER . Release the park brake. Bleed the hydraulic brake system. See MANUAL BLEEDING under BLEEDING, FILLING & FLUSHING BRAKE SYSTEM.
