What wheel cylinders are and where they are located?

A wheel cylinder is a component of a hydraulic drum brake system. It is located in each wheel and is usually positioned at the top of the wheel, above the shoes. Its function is to exert force onto the shoes so as to bring them into contact with the drum and stop the vehicle with friction.

Can you replace just one wheel cylinder?

While this isn’t a bad idea, it’s not necessary. You can just replace one wheel cylinder if it’s leaking. Another common misconception is that you need to remove the brake shoes to replace a wheel cylinder.

Should wheel cylinders be replaced in pairs?

It’s recommended you replace the brake wheel cylinder in pairs, especially when replacing other rear brake components. However, you should complete this job one wheel at a time. Remove one wheel and tire and complete the brake service on that wheel before moving to the other side.

What’s the difference between master cylinder and wheel cylinder?

Pressing on the brake pedal generates a hydraulic pressure in the master brake cylinder which is transmitted to the wheel cylinder in the brake fluid via the brake lines. In the wheel cylinder, the hydraulic pressure acts on the pistons, which then exert mechanical pressure on the brake shoes.

What happens when a wheel cylinder goes bad?

One of the first and most distinct symptoms of a bad wheel cylinder is a “mushy” brake pedal. If the wheel cylinders are leaking, their ability to pressurize and extend the piston may be compromised. This makes the brake feel strangely soft or mushy as if the brake slowly sinks to the ground when it is depressed.
