What is the purpose of the brake drum wheel cylinders?
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.
What’s the residual pressure on a drum brake?
These residual check valves are used on drum brake systems to keep around 5 psi. up to 12 psi. of pressure on the wheel cylinder’s cup seals and resist any momentum of brake fluid returning to the master cylinder.
What are the cylinders on a drum brake system?
Average rating from 206 customers who received a Brake System Inspection. Brake wheel cylinders are a component found on modern drum brake systems. They are the hydraulic component that extends to press the brake shoes against the brake drum when the pedal is depressed.
How does spring pressure work on drum brakes?
Once this occurs, spring pressure closes the valve maintaining low pressure on the drum brakes. Many vehicles today use cup expanders in the wheel cylinders that keep an airtight seal.
When does the rear drum brake pop out?
Discussion in ‘ Gen 2 Prius Care, Maintenance and Troubleshooting ‘ started by prscht, Mar 8, 2010 . I pressed the brake pedal while the left rear drum was off of the car. Then there’s a popping sound and brake fluid squirted out of the rear brake cylinder.

Is the brake wheel cylinder designed to wear out?
The brake wheel cylinder is the primary part that helps the brake shoes apply pressure to the inside of the drum, thereby slowing the vehicle down. Unlike brake shoes or pads or the brake drum itself, the brake wheel cylinder is not designed to wear out. In fact, it’s very rare that this component breaks or fails at all.
Once this occurs, spring pressure closes the valve maintaining low pressure on the drum brakes. Many vehicles today use cup expanders in the wheel cylinders that keep an airtight seal.
