Hydraulic System: Testing and Inspection

Hydraulic Leak Check

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 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.
3. Verify that the reservoir level is dropping.
4. If the reservoir level is dropping, inspect the brake components, fittings and lines to locate the source of the leak.
