For 1990-2009 cars

Notice: When filling the master cylinder, use only Delco Supreme 11, GM P/N 12377967 (Canadian P/N 992667), or equivalent DOT 3 brake fluid. Do not use a container which has been used for petroleum based fluids, or a container which is wet with water. Petroleum based fluids will cause swelling and distortion of rubber parts in the hydraulic brake system, and water will mix with brake fluid, lowering the boiling point. Keep all fluid containers capped to prevent contamination.

Important:

• | Lubricate the rubber parts with clean brake fluid to ease assembly.

• | Do not use lubricated shop air on brake parts or damage to the rubber components may result.

• | Bleed all or part of the brake hydraulic system if hydraulic component(s) are removed or disconnected.

• | The tightening specifications specified are for dry unlubricated fasteners.

• | Perform the service operations on a clean bench. Ensure the bench is free of all mineral oil materials.

The master cylinder must be kept properly filled to ensure the following conditions:

• | To ensure an adequate reserve.

• | To prevent air from entering the brake hydraulic system.

Caution: Do not overfill the brake fluid reservoir. Overfilling the brake fluid reservoir may cause the brake fluid to overflow onto the engine exhaust components during brake system service. The brake fluid is flammable and may cause a fire and personal injury if the brake fluid contacts the engine exhaust system components.

Brake fluid expands due to heat absorbed from the brakes during brake applications as well as heat from the engine compartment. Do not overfill the brake fluid reservoir.

Add brake fluid GM P/N 12377967 (DOT 3) or equivalent only as required to bring the level up to the FULL mark on the reservoir. Clean the brake master cylinder reservoir and the reservoir cover thoroughly before removal to avoid getting dirt into the reservoir. The brake fluid level sensor float (integral to the cover) seats when the brake fluid is filled to the FULL mark on the reservoir. Do not overfill.
