Non-Pressure Leaks
WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The wet appearance on the outer cover of rubber brake hoses is called sweating. This is a normal condition for neoprene rayon-braided hose. The sweating condition is not evidence of a brake fluid leak and will not result in a loss of pressure in the system.
The only part of the brake system that could have a brake fluid loss that does not appear when the system is under pressure is the brake master cylinder reservoir under the following conditions:
- Missing or poorly-fitted brake master cylinder filler cap
- Punctured or otherwise damaged brake master cylinder reservoir
- Missing or damaged brake master cylinder filler cap gasket
- Missing, damaged or poorly-fitted sealing grommets between the brake master cylinder and the brake master cylinder reservoir
The brake master cylinder reservoir grommets are not serviceable. They are included with a new brake master cylinder reservoir.
