TheWilwood Engineering Wilwood Integral Reservoir Compact Master Cylinder (Part Number 260-1304) offers a Girling style design. It features a 3/4-inch assembly. Compact and efficient. Ideal for tight spaces. Reliable performance.
The master cylinder reservoir should always hold enough fluid to allow the brake pads to completely wear away without the risk of running out of fluid. As a disc brake pad wears, the caliper piston will extend out of its bore. As the caliper piston extends, the master cylinder fluid level will drop in order to fill the caliper bore with brake fluid. If the reservoir is too small, there is a possibility that the master cylinder can run out of fluid and the brakes will fail.
Does a 4 wheel disc need a different proportioning valve?
Not when you buy one of our CPP proportioning valves. Our proportioning valve will work with both disc/drum or disc/disc applications.
What does a brake proportioning valve do?
A brake proportioning valve regulates the brake fluid pressure between the front and rear brakes, ensuring balanced braking power.
What size fitting is the back of the proportioning valve?
The fitting size is 9/16-18" but we sell a kit that would accommodate any popular size adapter (part number CP2091) which includes 3/8-24", 7/16-24", and 1/2-20".
Do I need a proportioning valve when upgrading from drum to disc?
Yes! A proportioning valve is needed to ensure the proper amount of brake fluid pressure is going to the front and rear wheels.
