Here are some signs you might see when you have a brake problem along with what might be causing them: Squealing Or Grinding NoisesĪlso read: Brake Repair | Brake Service – Midas Since your car’s braking system experience a lot of heat and friction, it will wear down over time and need to be serviced or even replaced. The video below explains how drum brakes work: Signs You Need Your Brakes Serviced 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 less 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. Here’s a video from Donut Media explaining how the brake system works: How Drum Brakes WorkĪs mentioned, drum brakes also operate with hydraulic pressure and use friction to slow down the car. You may also need to replace the brake lines and cylinders from time to time. This is why you need them serviced or replaced from time to time. Over time, they will wear down and they won’t work as well. The rotor, the caliper, and the brake pads all have to deal with a lot of friction and heat when you brake. When the brake pads inside the calipers come into contact with the rotor, they will slow the rotation of the rotor which slows down your wheels and your car. Once the fluid reaches the cylinders, it will move the pistons which then move the calipers inwards. This will then pump the brake fluid through the brake lines into the secondary cylinders at each of the wheel’s brakes. When you press the brake pedal, the master cylinder will apply hydraulic pressure to the system. Additionally, some pistons will force the calipers to move with the help of hydraulic pressure, cylinders, and brake fluid. Within the calipers are the brake pads that will come in contact with the rotor. 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 stops 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.
