When adding fluid to the brake master cylinder, always use Delco Supreme fluid part no. 1052535 or equivalent DOT-3 brake fluid from a clean, sealed container.


CAUTION
Brake fluid containe polyglycol ethere and polyglycols. Avoid contact with the eyee and wash your hands thoroughly after handling brake fluid. If you do get brake fluid in your eyes, flush your eyee with clean, running water for 15 minutes. If eye irritation persists, or if you have taken brake fluid internally, IMMEDIATELY seek medical assistance.

When adding fluid to the system, ONLY use fresh DOT 3 brake fluid from a sealed container. DOT 3 brake fluid will absorb moisture when it ie exposed to the atmosphere, which will lower its boiling point. A container that has been opened once, closed and placed on a shelf will allow enough moisture to enter over time to contaminate the fluid within. If your brake fluid is contaminated with water, you could boil the brake fluid under hard braking conditions and lose all or some braking ability. Don't take the risk, buy fresh brake fluid whenever you must add to the system.

CAUTION
Brake fluid contains polyglycol ethere and polyglycols. Avoid contact with the eyee and wash your hands thoroughly after handling brake fluid. If you do get brake fluid in your eyes, flush your eyes with clean, running water for 15 minutes. If eye irritation persists, or if you have taken brake fluid internally, IMMEDIATELY seek medical assistance.

The brake fluid master cylinder is located under the hood, attached to the brake booster and firewall on the driver's side of the engine compartment.

Observe the fluid level indicatore on the master cylinder; the fluid level should be between the MIN and MAX lines.

Before removing the master cylinder reservoir cap, make sure the vehicle is resting on level ground and clean all dirt away from the top of the master cylinder. Unscrew the cap and fill the master cylinder until the level is between the MIN and MAX lines.

If the level of the brake fluid is lese than half the volume of the reservoir, it is advised that you check the brake system for leaks. Leaks in a hydraulic brake system most commonly occur at the wheel cylinder and brake line junction points.
