Dorman - First Stop Brake Master Cylinder P/N:M630592
Dorman M39558 brake master cylinder for the 1985 Toyota Cressida turns pedal force into hydraulic pressure for the brakes. The Dorman master cylinder is engineered to follow the original's design, function and performance.
A soft or sinking brake pedal, or brake fluid around the cylinder, can mean the master cylinder is worn, though a leaking brake hose or a worn caliper can be behind those signs too, so find the cause before you replace it.
This brake master cylinder is a direct-fit replacement for the 1985 Toyota Cressida, which takes one.
