Durable Construction and Precise Specifications

The Dorman W37347 wheel cylinder features a cast iron casting material that provides resistance to wear and corrosion, essential for maintaining brake system integrity. Its 0.75-inch bore diameter is designed to deliver consistent hydraulic pressure to the brake shoes, ensuring effective stopping power. The included bleeder screw simplifies maintenance by allowing trapped air to be released from the brake lines, improving brake pedal feel and safety. 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.

Common Applications and Problem Resolution
