Durable Construction and Precise Specifications

The Dorman W37223 wheel cylinder features a cast iron casting material that provides long-lasting resistance to wear and corrosion. Its 1.125 inch bore diameter is designed to match specific drum brake assemblies, ensuring proper hydraulic pressure and brake shoe movement. The included bleeder screw simplifies maintenance by allowing trapped air to be released from the brake lines, improving brake responsiveness. The brake line inlet thread diameter of 0.437 inches and dual 7/16-24 brake component inlet threads provide secure connections to the vehicle’s brake system.

Compatible Vehicles and Common Applications

This drum brake wheel cylinder is compatible with various makes and models requiring a 1.125 inch bore diameter and matching thread sizes. It is commonly used in vehicles where the original wheel cylinder has worn or developed leaks, leading to reduced braking efficiency.

• Restores braking performance by replacing leaking or seized wheel cylinders
• Eliminates brake fluid leaks that cause low brake pedal pressure
• Prevents uneven brake shoe wear due to inconsistent hydraulic pressure
• Addresses spongy or soft brake pedal feel caused by air in brake lines
• Improves overall brake system reliability and safety

Installation Notes and Tips

When installing the Dorman W37223 wheel cylinder, ensure the brake system is properly bled using the included bleeder screw to remove air pockets. Verify that the brake line inlet threads and brake component inlet threads match the vehicle’s specifications. Inspect brake shoes and drums for wear and replace if necessary to maintain optimal braking performance. Use appropriate tools to avoid damaging the cast iron casting during installation.
