Durable Construction and Precise Specifications

The Dorman W9697 wheel cylinder features a robust cast iron body designed to withstand the rigors of brake system pressure and heat. Its 1-inch bore diameter provides the necessary piston size to apply even force to the brake shoes. The included bleeder screw simplifies maintenance by allowing trapped air to be released from the brake hydraulics, improving brake responsiveness. Thread sizes are standardized with a 0.437-inch brake line inlet and a 7/16-20 UNF brake component inlet, ensuring compatibility with original equipment brake lines and fittings.

Compatible Vehicles and Applications

This drum brake wheel cylinder is compatible with various vehicle makes and models that require a 1-inch bore diameter and matching thread sizes. It is commonly used in older domestic and import vehicles equipped with drum brake systems. For example, it fits certain Ford, Chevrolet, and Dodge models from the 1980s and 1990s that utilize similar brake hydraulics specifications. Always verify fitment with your vehicle's service manual or parts guide before purchase.

Common Brake Issues Addressed

• Brake pedal feels spongy or soft due to leaking wheel cylinder
