What is the wheel cylinder?

The wheel cylinder operates as part of the drum brake system. When you push the brake pedal, the cylinder applies force onto the brake shoe, pushing it against the drum to start slowing down your vehicle.

Here are some telltale signs of a faulty wheel cylinder:

-The brake pedal feels spongy when pressing it down
-Brake performance is reduced
-Brake fluid is leaking
