The cars that have a drum braking system have a brake wheel cylinder that is meant to cause friction between the brake drum and the brake shoes. This friction allows the car to slow down. So, on malfunctioning, brake wheel cylinder replacement should be done immediately to avoid mishaps. Let’s find out more in this blog.
What is a Brake Wheel Cylinder?
Brake wheel cylinders are located inside the brake drums. When you apply the brake in a rear brake system. the brake wheel cylinder pushes the brake shoes against the brake drum. The resulting friction causes the vehicle to slow down and stop at the right time. Due to the amount of heat and pressure the wheel cylinders are exposed to, the wheel cylinder cylinders tend to wear out over time. This causes the brake fluid to leak, reducing the effectiveness of the brake system.
It is important to note that brake wheel cylinders are to be replaced in pairs even if only one has worn out.
Why is Brake Wheel Cylinder Replacement Important?
For a vehicle to slow down and stop, friction must occur between the brake drum and the brake shoes in case of a drum brake system, and between the brake rotor and brake pad in case of a disc brake system. In a drum brake system, causing this friction is the job of the brake wheel cylinder residing inside the brake drum.
So, if the seal of the cylinder is broken or the cylinder is malfunctioning, it won’t be able to effectively produce friction. This will result in increasing the stopping distance of the car which can effectively become a safety hazard.

- If you hear noise coming from the rear brakes, it might be because of the brake wheel cylinders
- If the brake fluid is leaking near the rear tyres, brake wheel cylinders might be the culprit
