Rebuild a leaking front drum brake wheel cylinder with the Dorman - First Stop Drum Brake Wheel Cylinder Kit 39070. It's a direct-fit repair kit for the front drum brakes on the 1960-1970 Ford Falcon, 1964-1970 Ford Mustang, 1970 Ford Maverick, 1960-1965 Ford Ranchero, 1960-1965 Mercury Comet, and 1964 Mercury Cyclone (All engines). The wheel cylinder is the hydraulic actuator that pushes the brake shoes against the drum; this kit refreshes the seals and rubber inside the existing cylinder rather than replacing the whole unit. If worn internal cups and boots are the cause of a fluid leak or soft pedal, this kit replaces them.
- What's in the kit: wheel cylinder cups, dust boots, and seals to service the cylinder bore.
- Bore size: built for a 1.063 in bore.
- Not included: wheel cylinder pistons, the expander spring, the bleeder screw and cap, and mounting hardware are not part of this kit.

The listed applications use two per vehicle, so order two kits to service both front wheel cylinders. Country of origin: China.
