Brake System Leak Check
Brake System Leak Check1. 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 the rain or snow.
Make sure the brake master cylinder reservoir is full.
2. Apply the brakes several times and make sure the brake pedal feel is not spongy. If necessary, bleed the system. For additional information, refer to Brake System Bleeding.
3. If the brake reservoir level is going down, inspect the brake components, fittings, tubes and hoses to locate the source of the leak.
