Dorman - First Stop Drum Brake Wheel Cylinder P/N:W3677
Restore firm, even rear drum braking on your Toyota Pickup with the Dorman - First Stop Drum Brake Wheel Cylinder (W37654). Mounted in the rear drum brake, this hydraulic cylinder houses pistons that push the brake shoes outward against the drum when you press the pedal. It's a direct replacement for the rear (left or right) position on the 1985-1990 Toyota Pickup [All] (two per vehicle), the 1991 Toyota Pickup [All] (one), and the 1992-1993 Toyota Pickup [All] (two per vehicle).
Replacing the cylinder while servicing your drum brakes is a fast, cost-effective way to help maintain reliable brake performance. If a leaking or seized wheel cylinder is the cause of a soft pedal or fluid at the drum, this replaces it. Country of origin: China.
