Optimize the performance and consistency of your drum brake system with the Wilwood 10 lb Residual Pressure Valve. This valve is specifically designed to retain a minimum brake line pressure, helping to eliminate excessive pedal travel and ensuring reliable wheel cylinder operation in drum brake applications.
How It Works:
In drum brake systems, the brake shoes are held away from the drum by return springs. When the brake pedal is released, these springs can quickly pull the shoes and fluid back, potentially causing a delay in brake engagement and a soft pedal feel upon the next application.
The 10 lb residual pressure valve is used specifically with drum brakes to compensate for this return spring tension. By maintaining a constant 10 PSI of pressure in the lines, the valve ensures the wheel cylinders remain sealed and primed, allowing for immediate brake engagement and a firm, consistent pedal.
Key Features:
-
Engineered for Drum Brakes: The 10 lb pressure rating is specifically calibrated to overcome the tension of drum brake return springs and maintain optimal wheel cylinder sealing.
-
Eliminates Excessive Pedal Travel: Helps to maintain a firm brake pedal, reducing the "dead zone" often associated with drum brakes.
-
Durable Construction: Made from high-quality billet aluminum for strength and longevity.
-
Color-Coded: Easily identifiable for correct application.
-
Versatile Fitting Options: Available with or without additional fittings. Valves equipped with fittings are supplied with two 1/8-27 NPT to 3/8-24 inverted flare female fittings, compatible with most domestic 3/16th hard brake lines.
Wilwood Residual Pressure Valve Series:
Wilwood offers a range of residual pressure valves for various braking applications:
-
2 lb Valves: Used in disc brake applications, particularly when the master cylinder is mounted below the calipers, to prevent fluid drain back.
-
4 lb Valves: Beneficial for high-vibration environments such as off-road or dirt circle track racing.
-
10 lb Valves: Essential for drum brake systems to maintain wheel cylinder sealing.
Ensure reliable and consistent performance in your drum brake system with the Wilwood 10 lb Residual Pressure Valve.
