For 1990-2009 cars

Notice: Use only DOT 3 brake fluid from a clean, sealed container. Do not use any fluid from a container which is wet with water. Do not use DOT 5 silicone brake fluid. Improper brake fluid, mineral oil or water in the fluid may cause the brake fluid to boil or the rubber components to deteriorate. Keep all fluid containers capped to prevent contamination.

• | A properly filled master cylinder reservoir ensures adequate reserve, and prevents air and moisture from entering the hydraulic system.

• | Do not overfill the master cylinder reservoir. Heat that is absorbed from the brakes and the engine will cause the master cylinder reservoir to expand.

• | Do not add fluid if the brake hydraulic system is not leaking.

• | The master cylinder reservoir is a part of the master cylinder assembly.

| The master cylinder reservoir is located under the hood on the driver's side of the vehicle.

• | Fill reservoir using Delco Supreme No. II Hydraulic Brake Fluid (GM P/N 12377967) or the equivalent, DOT-3 motor vehicle brake fluid.

1. Thoroughly clean the master cylinder reservoir cover before removal in order to avoid getting dirt into the reservoir.
2. Remove the cover and the diaphragm.
3. Add the fluid as required in order to bring the level to 20-26 mm (0.78-1.0 in) blow the filler neck inside the reservoir.
