Non-Pressure Leaks

Non-Pressure Leaks
An empty brake master cylinder reservoir condition may be caused by three types of nonpressure external leaks:
Type 1: An external leak may occur at the brake master cylinder filler cap because of improper positioning.
Type 2: An external leak may occur at the mounting end of the brake master cylinder because of a bore end seal leak.
Type 3: An external leak may occur in the rubber hoses between the brake master cylinder reservoir and brake master cylinder. Check the rubber hoses for damage. Repair as necessary.
