Brake System Leak Check

Material:

Check

WARNING: Use of any other than approved DOT 3 brake fluid will cause permanent damage to brake components and will render the brakes inoperative. Failure to follow these instructions may result in personal injury.

WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush eyes with running water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately. Failure to follow these instructions may result in personal injury.

CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface, immediately wash it with water.

1. NOTE: Brake fluid is water soluble and it is possible that all evidence of fluid leakage has been washed off if the vehicle has been operated in rain or snow.

Check the brake fluid level. Add brake fluid as necessary.
2. Apply the brakes several times and make sure the pedal feel is not spongy. If necessary, bleed the brake system.
3. Check the brake fluid level and verify that the fluid level is actually dropping.

4. NOTE: If the brake fluid level drops and no external leak is evident, check for a brake master cylinder bore end seal leak.

Locate and correct the external leak.
