Description:

• GM brass proportioning valve Disc Drum brake applications.
• This valve is solid brass, making it long lasting and heavy duty.
• It performs all the necessary functions when using disc brakes in the front and drum brakes in the rear.
• This valve will reduce braking pressure to the rear when necessary to prevent the brakes from locking up.
• It also distributes the brake pressure evenly so that the disc brakes are not doing all the work.
• This valve will also act as residual pressure the rear drum brakes, allowing better responsiveness when the brakes are applied.
• It also has a brake warning light switch to alert you if there is any failure in the braking system.
• This valve is a great upgrade over the original and is a must when upgrading from drum to disc brakes.
• This is a GM style valve, but will work on almost any Chevy as long as you have the right fittings.
