Rebuild a leaking rear drum brake wheel cylinder instead of swapping the whole unit with the Dorman - First Stop Drum Brake Wheel Cylinder Kit 8418. This kit is a direct replacement for the wheel cylinder's internal parts on the listed rear applications, including the 1946-1958 Jeep Willys, 1959-1966 Jeep CJ5, 1983-1984 Mazda B2000, 1963-1964 Studebaker Avanti and 1971-1974 Toyota Celica — see the Buyer's Guide tab for the full list. Inside the wheel cylinder, hydraulic pressure from the brake line pushes the cups outward to force the brake shoes against the drum.
This kit is sold individually; the listed applications use two per vehicle (one per rear wheel cylinder), so order two and service both sides together to help keep braking balanced. If a worn or leaking wheel cylinder is the cause of your brake trouble, these components are designed to match the original parts. Country of origin: China.
