Dorman - First Stop Drum Brake Wheel Cylinder Kit P/N:33171

When a rear drum brake wheel cylinder starts weeping brake fluid past worn cups, the Dorman First Stop Drum Brake Wheel Cylinder Kit (MPN 33171) supplies the internal parts needed to rebuild it. It's offered as a direct replacement for the original wheel cylinder components on a wide range of classic and light-truck applications, including the 1962-1964 Plymouth Fury [All], 1966-1975 Ford Bronco [All], 1967-1968 Ford Mustang [All], and 1995-2009 Ford Ranger [All] — see the Buyer's Guide tab for the full list of 39 applications.

• Direct replacement: the components are sized to match the original wheel cylinder parts required to repair the cylinder on the listed vehicles.
• Fits a 0.813 in bore: built for wheel cylinders with a 0.813 in bore size.
• What's included: dust boots, wheel cylinder cups, and seals.
• Not included: wheel cylinder pistons, expander spring, mounting hardware, bleeder screw, and bleeder screw cap — transfer serviceable originals or source them separately as directed by the service procedure.
• Durable construction: made from quality components for dependable performance.

The wheel cylinder uses hydraulic pressure from the brake system to push the brake shoes outward against the drum; over time the internal cups and boots wear, letting fluid seep past and allowing contaminants in. If worn seals are the cause of a leaking rear wheel cylinder, this kit rebuilds the existing unit rather than replacing the whole cylinder. The listed applications use two rear wheel cylinders (one per side), so order two kits for a complete rear-axle repair. Manufacturer part number 33171. Country of origin: China.
