Detailed Product Description

The Dorman W37979 drum brake wheel cylinder is specifically designed to meet the brake hydraulics requirements of Volkswagen EuroVan vehicles. Its cast iron casting material provides robust resistance to wear and corrosion, essential for maintaining brake system integrity. The bore diameter of 0.813 inches ensures proper piston movement within the cylinder, contributing to effective brake application. 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 10 mm and M10 x 1.0 thread size with a 1.0 pitch ensure compatibility with the original brake line fittings on the EuroVan.

Common Applications and Problem Resolution

• Replaces leaking or damaged drum brake wheel cylinders on Volkswagen EuroVan
• Addresses brake fluid leaks that reduce braking efficiency

• Prevents brake failure due to worn or corroded wheel cylinders

Installation Notes and Tips

When installing the Dorman W37979 wheel cylinder, ensure the brake system is fully depressurized and the vehicle is securely lifted. Use the included bleeder screw to properly bleed the brake lines after installation to remove any air pockets. Verify that the brake line inlet threads match the M10 x 1.0 specification to avoid cross-threading. Inspect brake shoes and hardware for wear during installation and replace as necessary to maintain optimal braking performance.
