Do drum brakes have 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 is a drum wheel cylinder?
What does a wheel cylinder do? In a drum brake system, the Wheel Cylinder puts pressure on the brake shoes, which when pressed against the drum, slows down and stops the vehicle. The cylinder is connected to the shoes by small rods.
Do you have to replace both wheel cylinders?
Some people think that if you have one bad wheel cylinder, you should replace them both. While this isn’t a bad idea, it’s not necessary. You can just replace one wheel cylinder if it’s leaking. You can often crank out the self adjuster to spread the shoes away from the wheel cylinder to gain access to it.
How much does it cost to replace a rear wheel cylinder?
The average cost for brake wheel cylinder replacement is between $157 and $192. Labor costs are estimated between $96 and $121 while parts are priced between $62 and $71. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
How do I know if my drum brake cylinder is bad?
What Are The Symptoms Of A Faulty Wheel Cylinder? Your car has poor brake response, and you’ll find that braking takes longer. Your brake pedal feels mushy, soft or the pedal sinks to the vehicle floor. There’s a brake fluid leak in your rear brake drum that pools near a rear wheel. The rear drum brakes drag or lock up.
How long do drum brake cylinders last?

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.
Can you rebuild a wheel cylinder?
Wheel cylinders should be rebuilt or replaced in pairs. Even if only one is leaking, it’s advisable to rebuild or replace both sides. If you find that only one is rebuildable, it’s OK to rebuild the one and replace the other with a new cylinder.
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.
Do you need to replace wheel cylinder on drum brakes?
No, the wheel cylinder isn’t designed to wear out like brake shoes or brake pads. However, its seals can break and leak over time. It’s always advisable to replace the wheel cylinder during a brake shoe replacement, as this will avoid additional labor and workshop time.

Why do rear brake pistons rotate?
The thread of the parking brake mechanism has to allow the cylinder to move along it to compensate for the pad wear but it is still free to rotate one way, then the other, to work. When you replace the pads you are merely rewinding the piston along the thread.
Can you replace a section of brake line?
Brake lines aren’t routed the same way in all vehicles. However, replacing your brake line is usually a quick process. With a professional mechanic, it takes about one to two hours. Your mechanic will have to remove the old brake line and put in a new one, or splice the bad section and replace it.
Can I drive with a leaking rear wheel cylinder?
If you suspect your brake fluid is leaking, do not attempt to drive it. Look under your hood and check the brake fluid reservoir. An empty reservoir means that your brakes have been leaking for a while. Have your vehicle towed to your mechanic for a professional repair.
