It is also a great choice for your disc front brakes and disc rear brakes!
This is a brand new Disc/Disc residual brake pressure valve set (TWO valves).
They are the 2 pound pressure valves (blue) for disc brakes.
These valves are used with any disc brake application where the master cylinder is located under the floor.
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.
These valves will act as a one way check valve that prevents this type of bleed-back.
Without it, there is a good chance that the brakes will drag or give out completely!
These valves are an inexpensive and necessary addition to your brake system.
This is for TWO valves, one for the front discs and one for the back discs.
Package: Including all items in the picture.
Note: Professional Installation is Highly Recommended.
