Durable Construction and Precise Specifications

The Dorman W37805 wheel cylinder features a cast iron casting material that provides resistance to wear and corrosion, essential for maintaining brake system integrity. Its 1.125-inch bore diameter is designed to deliver the correct hydraulic force to the brake shoes, ensuring effective braking response. The included bleeder screw simplifies maintenance by allowing trapped air to be released from the brake lines, which is critical for optimal brake performance. The brake line inlet thread diameter of 10 mm with an M10 x 1.0 thread size and 1.0 thread pitch ensures compatibility with specific brake line fittings, making it suitable for certain vehicle models requiring these specifications.

Compatible Vehicles and Applications

This drum brake wheel cylinder is compatible with various makes and models that require a 1.125-inch bore diameter and M10 x 1.0 brake line inlet threads.
