The main type of braking system on most cars is disc brakes, the main element of which is the brake disc. The system starts working with the depressing of the pedal, and this force is transmitted to the brake discs of all wheels.
Instructions
Step 1
Look in your car's service book - find out what type of braking system is installed on it. Braking systems differ from one another in the type of drive. So the vast majority of passenger cars are equipped with a hydraulic drive, and trucks - pneumatic or combined. To facilitate the driver's braking effort, vehicles are equipped with pneumatic or vacuum brake boosters.
Step 2
All car manufacturers, without exception, strive to make brake discs from durable modern materials, using the latest technological developments. When choosing discs, you should first of all be guided by the diameter and design of the basic configuration. Standard discs will have the best performance. They are the most resistant to deformation. Ventilated brake discs are one of the promising developments. This innovation helps to avoid overheating of the brake pads, especially in urban conditions, which are characterized by frequent changes in speed and stopping modes.
Step 3
Look at the size of the diameter - this is the main difference between all brake discs. The larger diameter of the brake disc will be matched with larger brake pads, which increases the braking efficiency.
Step 4
Efficiency is also influenced by perforation - holes located across the entire surface of the disc and designed to remove the gas cushion. The gas cushion is created by friction between the pad and the disc. Perforation also helps to get rid of moisture.
Step 5
Some types of discs can have radial notches - special grooves for cleaning the working surface of the discs from wear products of pads, road dirt. Radial grooves ensure even pad wear. To protect discs from the harmful effects of rust, various types of anti-corrosion coatings are widely used, which should also be considered when choosing brake discs.
