A soft or sinking brake pedal, fluid leaking at the cylinder or a brake warning light can point to a failing master cylinder. These signs alone do not prove the cylinder is the problem, since a leaking brake line can give you a soft pedal too.
Fits
The same brake master cylinder fits the 1993-1997 Mercury Cougar and the 1993-1996 Lincoln Mark VIII. A brake system needs just one master cylinder, and this listing is one.
