If a fluid leak occurs in one circuit, only two of the wheels will lose their brakes and your car will still be able to stop when you press the brake pedal. The master cylinder supplies pressure to both circuits of the car.It is a remarkable device that uses two pistons in the same cylinder in a way that makes the cylinder relatively failsafe.The combination valve warns the driver if there is a problem with the brake system, and also does a few more things to make your car safer to drive.In this article, we will learn how the master cylinder and combination valve work.he master cylinder supplies pressure to both circuits of the car. It is a remarkable device that uses two pistons in the same cylinder in a way that makes the cylinder relatively failsafe.
