Components of a Car’s Brake System And How a Mechanic Repairs Them – Part I

by Lilydale Motors 2019-08-09
The braking system of a car plays a vital role. It consists of different major components such as brake pads, pedals, master cylinder, brake fluid, disc or drum, calipers and many more. Know about these brake components in detail and the method followed by a car mechanic to repair or replace them.

Brake Pads Replacement

The brake pad is the heart of the entire braking system of a car and it is made up of high-heat resin and metal. The working principle of brake pads is simple. When you press the brake pedal then the brake pads lock the rotors of car wheels and decreases the speed of the car. According to car experts, brake pads must be checked or replaced every 5000 miles. In general, pads last for maximum 40000 miles. When any problem arises in the brake pads, the car mechanics replace the component in the following way: 
  • Firstly, they lose the lug nuts by using a lug wrench
  • Then they lift up the car with the help of screw jack
  • After that, experts remove the wheel very carefully
  • Once removing them, they open the caliper bolt by using ring-spanner or socket
  • After that, they remove the old pads and replaces with the new one
  • Then they check the brake fluid and its condition
  • Once done, the caliper is reinstalled and the wheel is put back


Master Cylinder Replacement

Master cylinder or brake booster is the most essential part of a car’s brake system. It is mounted inside the engine compartment. Master cylinder controls the brake fluid. Generally, the brake pedal is attached with this cylinder hydraulically. When the pedal is pressed then the valve of the cylinder opens and brake fluid moves towards the brake pads. Professionals use these following steps to repair a faulty master cylinder. 
  • Firstly, the brake fluid is completely removed from the brake fluid reservoir.
  • After that, they remove the brake fluid sensors and the brake fluid lines respectively.
  • Once done, experts detach the brake master cylinder and installs the new cylinder.
A car’s braking system consists of many components. Here we have discussed only two of them- brake pads and master cylinder. We will discuss more the other components and how an expert repairs them in our next blog. Till then, stay connected with us.
