Application: --This valve can be used with any DISK brake application as long as the master cylinder is located under the floor. Description: --Brand new 2 pound residual pressure valve in blue. --When the master cylinder is under the floor, it is usually lower than the calipers. --Gravity and vibration can cause brake fluid to leak back to the master cylinder away from the calipers, causing a loss of brake pressure. --This valve acts as a one way check that prevents this type of bleeding. Without it, your brakes could drag or give out completely. --This valve is necessary to your brake system
