When a piston is sticky, it won’t retract properly and your caliper will still come into contact with the rotor even when you let go of the brake pedal. When the caliper hits that area as you brake, you will feel a vibration since the surface of the rotor isn’t smooth.Ī sticky piston may also cause vibrations during braking. It’s also possible that some brake pad material is sticking to the rotor, creating a bump on the rotor. This is why the rotors sometimes need to be smoothed and evened out during servicing. It’s normal for the rotors to have variations, but when their difference in thickness is big enough, this can cause wobbling and vibrations when you brake. Since the brake discs or rotors have to deal with friction, over time they will wear down. If you have drum brakes, try applying brake lubricants and it should solve the problem. If your front brakes are wet, the squealing noises should go away after you’ve driven for a while. But because some cars still use drums for the rear brakes since they’re cheaper and rear brakes don’t need to do much anyway in most driving conditions, and are mostly used as a parking brake. In most scenarios, disc brakes are clearly superior. They are also a bit more complex, thus making maintenance more time-consuming even if they don’t require it very often. This results in vibrations and the driver needs to press the brake pedal farther. When it overheats, the drum can distort and increases in diameter due to thermal expansion. However, drum brakes are prone to overheating. They are also generally cheaper to maintain and require fewer maintenance thanks to better corrosion resistance. They also have other advantages, such as providing more braking force than an equal-diameter disc brake. Most modern cars will use disc brakes, but older cars and some entry-level vehicles still use drum brakes for the rear brakes since they’re cheaper. This will then slow the drums down, which in turn will slow down the car’s wheels. These pistons will move the brake shoes outwards and they will come into contact with the drum. When you apply the brakes, the hydraulic pressure will push the pistons inside the wheel cylinder. The drum that rotates with the wheels houses these components. A drum brake consists of the backplate which serves as the base, the brake shoes, and the wheel cylinder which contains pistons and is connected to the hydraulic system. However, it has a different design to disc brakes. Within the calipers are the brake pads that will come in contact with the rotor.Īs mentioned, drum brakes also operate with hydraulic pressure and use friction to slow down the car. The disc brake consists of a rotor (the disc) that attaches to the wheel hub, which sits inside a caliper. But since most modern cars use disc brakes, we’ll focus on disc brakes first. They have different designs but both of them use hydraulic pressure to operate and stop the car by using friction. There are two types of brakes: disc and drum brakes. But why do they need servicing? Why do they wear down? Well, let us explain how your braking system works and why they need servicing or even a replacement job from time to time. It’s obvious just how important car brakes are. While we’re at it, we’ll also help you expand your knowledge on brakes in general. We’ll take a look at reviews and prices at the big chains, and give you some tips on what to look out for before you choose one. In this post, we’ll take a look at the cheapest place to get brakes done. We don’t need to tell you that your car’s brakes are very important – they stop you from having a crash! But since the brakes are such as important and major component, it’s no surprise that servicing or repairing them can be quite pricey.
