Dorman - First Stop Brake Master Cylinder P/N:M390362
Dorman M39743 brake master cylinder for the 1989-1992 Ford Probe and other vehicles turns pedal force into hydraulic pressure for the brakes. It is precision-engineered to follow the design and performance of the original master cylinder on specific vehicle years, makes and models.
A soft or sinking brake pedal, fluid around the cylinder or a brake warning light can mean the master cylinder is wearing out. These signs alone do not prove it is the problem, since a leaking brake line or caliper can produce them too, so have the brakes inspected promptly.
This brake master cylinder fits the 1989-1992 Ford Probe, the 1988-1992 Mazda 626 and the 1988-1992 Mazda MX-6, and each car takes one.
