Hydraulic Leak Check
- Make sure the brake master cylinder reservoir (2K478) is full.
- Apply the brakes several times and make sure the brake pedal (2455) feel is not spongy. If necessary, bleed the system. Refer to BLEEDING-SYSTEM .
- Hold pressure on the brake pedal for 30 seconds.
- Verify that the reservoir level is dropping.
- If the reservoir level is dropping, inspect the brake components, fittings and lines to locate the source of the leak.
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.
