FAQs

What is the bore size of this master cylinder?

This specific model features a 0.500 (1/2) inch bore size.

Does this master cylinder include a reservoir?

What is the thread size for the inlet port?

The inlet port features a standard 7/16-20 thread size.

Can this master cylinder be rebuilt?

What type of brake fluid should I use?

It is recommended to use a high-quality DOT 3 or DOT 4 brake fluid, depending on your system requirements and ambient operating temperatures.

Is this master cylinder suitable for power brakes?

This master cylinder is designed for manual brake systems or as a component in custom hydraulic brake systems. It is not a direct replacement for a power brake booster system.

Troubleshooting

Brake pedal feels soft or spongy.

Ensure the brake system is completely bled. Check all connections for leaks. Verify the remote reservoir is adequately filled and the inlet line is submerged.

Brake fluid leak at inlet fitting.

Tighten the fitting securely. Inspect the fitting and the threaded port for damage. Use appropriate thread sealant if necessary.

Master cylinder does not return brake pressure fully.

Check the integrity of the internal piston and return spring assembly. Ensure no obstructions are present in the bore. If issues persist, internal seals may need replacement.

Setup, Compatibility & Care Instructions

Setup: Ensure the master cylinder is correctly oriented and securely mounted. Connect the remote reservoir via the 7/16-20 threaded inlet using appropriate fittings and brake lines. Bleed the brake system thoroughly after installation to remove any air.

Compatibility: This master cylinder is designed to work with a remote brake fluid reservoir. Verify that the 0.500-inch bore size is appropriate for your specific brake system configuration (caliper piston area and rotor size). Consult with a brake specialist if unsure.

Care: Periodically inspect brake fluid levels in the remote reservoir. Clean the exterior of the master cylinder with a damp cloth. For internal maintenance or rebuilding, follow Wilwood's service guidelines, which typically involve disassembling, cleaning, and replacing seals.
