It is used in disc brake where the master cylinder is mounted below the horizontal plane of the calipers and fluid drain back occurs from gravity and vibration, thereby causing excessive caliper piston retraction and a longer brake pedal stroke.
The valve has pipe thread fitting in the ends, suitable for common 3/8-24 inverted flare brake line fitting.
Easy to install, but professional installation recommended.
Made of premium quality material, tough and durable in use.
Good choice to replace your old or worn pressure valve.
Features: It is used in disc brake where the master cylinder is mounted below the horizontal plane of the calipers and fluid drain back occurs from gravity and vibration, thereby causing excessive caliper piston retraction and a longer brake pedal stroke. The minimal 2LB residual pressure can prevent fluid from flowing back without causing the brakes to drag.  The valve has pipe thread fitting in the ends, suitable for common 3/8-24 inverted flare brake line fitting.  Easy to install, but professional installation recommended. Made of premium quality material, tough and durable in use. Good choice to replace your old or worn pressure valve.
