What is the braking principle of the car



      First of all, let's popularize , The principle of automobile braking : When the driver applies this brake pedal , This brake oil in the brake master cylinder will generate pressure , The fluid transfers pressure through the line to the piston in the caliper of each wheel , The piston tightens the brake pads and brake discs before driving the card , This creates friction , Slow down the vehicle .

     SO... The round brake disc is clamped by the brake pad in the brake caliper to realize tire braking , The brake disc and brake pad are not replaced for a long time , Large wear will occur , Cause the vehicle braking effect to deteriorate , Therefore, it is important to master the relevant knowledge of brake discs .




What is the brake disc ?


       brake disc , Simply speaking , It's a round plate , When the car is moving, it also rotates . The brake caliper clamps the brake disc to produce braking force , When stepping on the brake, it clamps the brake disc to slow down or stop . The brake disc has good braking effect , And easier to maintain than drum brake .

    The brake disc will generate a lot of heat under braking , So don't wash the car immediately after braking , The engine should be turned off to reduce the surface temperature of the brake disc , Prevent deformation and cracks of high temperature brake disc due to thermal expansion and contraction in contact with cold water .

    In addition, the best way to improve the service life of the brake disc is to maintain good driving habits , Try to avoid emergency braking and emergency stop .
