Wheel Cylinder
The wheel cylinder pushes brake shoes against the drum.
What is Wheel Cylinder?
It has pistons and seals. It can leak. It is used in drum brakes. A leaking wheel cylinder shows as damp brake fluid inside the drum and on the backplate, and contaminated shoes must be replaced. Seized pistons cause a brake to drag or pull to one side. Wheel cylinders are usually inexpensive and are often replaced together with shoes.
How it works
Hydraulic pressure moves the pistons.
Why it matters for your car
Leaks contaminate shoes. Replace leaking cylinders.
