How Do Porsche Rear Disc Brakes Work?

The braking system in your Porsche car breathes life into your ride. It is what you make use of to make sure you avoid accidents down the road. This system has different parts including Porsche rear disc brakes. Wonder what sets them apart from the front-wheel disc brakes? Want to know how they work? We have the answer to these questions down below.

What are Disc Brakes?

The very answer to the question about rear disc brakes can be provided once this question is answered. A disc brake is actually the main component responsible in making your vehicle stop in any situation that calls for one. They come with three main components namely the rotor, the brake pads, and the caliper.

How Do the Different Parts Work?

Basically, the rotor is that iron disc which is connected to the hub of your tires. They work alongside the brake pads when it comes to stopping the car's wheel. Brake pads, on the other hand, are found on every side of the rotor and are pushed against it to help when the vehicle needs to stop. It creates the friction necessary when stopping your vehicle.

Now let us go to the caliper. The caliper is that device found on top of the rotor where the brake pads are contained. There are different types of rotors that you may find. One is called a floating caliper which can work by compressing itself and has only one piston. Once brakes are applied when driving, the piston is forced back into the brake pad via the brake fluid which will then press against the brake rotor. The other part of this caliper will then press the other brake pad against that of the brake rotor when stopping the wheel and eventually the vehicle.

The other type is called the fixed caliper which has two pistons located on each side of the rotor and does not move. Whenever brakes are applied when driving, these pistons are forced by brake fluid into each brake pad which will then press on each of the two sides of the rotor thus eventually stopping the wheel and the vehicle.

What are Rear Disc Brakes?

Rear disc brakes are basically the same as front-disc brakes but they are different because rear disc brakes must always include an emergency or a parking brake. You have to take note that parking brakes must be separate from regular hydraulic brakes especially in cases when regular brakes will suddenly fail.

Rear Disc Brakes and Parking Brakes

There are two ways by which a parking brake is connected to a rear disc brake. First is the fact that rear disc brakes have a special corkscrew device that pushes a piston to the brake pad when parking brake is applied so that the vehicle can stop. There are also instances when the rear disc brake may include a separate drum brake system. In this case, cables in the parking brake will be responsible for pulling a lever found in the dumb brake whenever parking break is applied. This will then work by compressing the car's brake shoes in order to stop the vehicle.
