Dorman - First Stop Brake Master Cylinder P/N:M630794
Dorman M390296 brake master cylinder for the 1995-1998 Toyota T100 turns pedal force into hydraulic pressure that works the brakes.
A soft or sinking brake pedal, brake fluid around the master cylinder or a brake warning light can mean the cylinder is wearing out. Lines or calipers can also give a soft pedal, so first look for wet spots and check the fluid level with the engine off. A shop can pressure-test the rest.
This master cylinder fits the 1995-1998 Toyota T100, and each truck takes one. It is engineered to match the design, function and performance of the original master cylinder.
