Product Information

Full details

This 4oz Wilwood Billet Aluminium Brake Fluid Reservoir is designed for automotive enthusiasts and mechanics seeking a compact and durable fluid storage solution for brake or clutch systems. Its key benefit is direct mounting to compatible Wilwood master cylinders, saving space and simplifying installation. A potential caveat is its specific thread size (11/16''-20), which may limit direct compatibility with non-Wilwood master cylinders. The reservoir features a smooth billet aluminium body, a secure screw cap with an internal bellows seal, and a 4 oz fluid capacity, making it ideal for custom builds or tight engine bays.

FAQs

What is the thread size of this reservoir?

The reservoir features an 11/16"-20 thread size, designed for direct fitment onto compatible Wilwood master cylinders.

Can I use this with any master cylinder?

It is primarily designed for specific Wilwood master cylinders. For other master cylinders, you may need to use adapter fittings to match the thread size.

What type of fluid can I use with this reservoir?

This reservoir is suitable for standard DOT 3, DOT 4, or DOT 5.1 brake fluids, and compatible clutch fluids. Always refer to your specific system's requirements.

How much fluid does the reservoir hold?

The reservoir has a fluid capacity of 4 fluid ounces (approximately 118 ml).

What are the overall dimensions of the reservoir?

The reservoir measures 2.45 inches (62mm) in diameter and 4.25 inches (108mm) in height.

Does the cap have a seal?

Yes, the screw cap has an internal rubber bellows seal designed to protect the fluid from contamination and evaporation.

Is installation difficult?

Installation is generally straightforward if your master cylinder has the compatible 11/16"-20 thread. It screws directly on. If adapters are needed, additional steps will be involved.

Troubleshooting

Reservoir leaks at the connection point.

Ensure the master cylinder thread is clean and undamaged. Verify the 11/16"-20 thread specification. If using adapter fittings, ensure they are properly tightened and sealed. Consider using a thread sealant specifically designed for brake fluid applications if necessary.

Fluid level appears incorrect or inconsistent.

Check for air bubbles in the brake lines. Ensure the vehicle is on a level surface when checking the fluid level. Verify that the master cylinder is functioning correctly and not bypassing fluid.

Fluid becomes discolored or contaminated.

The internal bellows seal may not be seated correctly, or the cap is not fully secured. Ensure the screw cap is tightly sealed after filling. Follow recommended fluid flush and replacement intervals.

Reservoir shows signs of corrosion or damage.

Inspect the reservoir carefully. For minor external blemishes, a gentle polish might suffice. For significant damage or internal corrosion, replacement of the reservoir is recommended to maintain system integrity.
