Automobile brake system

At present, the mainstream household car brake form is: brake pad, brake disc composition.

Brake pad: generally composed of steel plate, adhesive heat insulation layer and friction block, the heat insulation layer is composed of no heat transfer material, the purpose is to heat insulation (if overheating is easy to cause the burning of the brake system). The friction blocks are pressed against the brake disc or drum during braking to create friction and thus decelerate the vehicle. As a result of friction, the friction block will gradually wear.


Brake disc: simply put, a round plate. Brake pad friction block clamps the brake disc and produces braking force. It clamps the brake disc to slow down or stop when braking.


What's the difference between a brake pad and a brake disc?

Bicycle everyone knows, as long as the hand a pinch brake, 2 brake leather clip wheel. Similarly, the principle of the car brake is the same, when you are driving, the foot on the brake is equal to the bicycle brake pinched, so that the brake shoe driving brake pad, the rotating brake disc friction, to achieve the braking effect.


So, the simplest difference between them is that the brake disc is rotating like the wheel, but the brake pads are stationary forever.


How often is it changed?

Replacement is subject to inspection results, brake brake is divided into the front brake and rear brake, generally every 5000 km to check once. Once found friction block loss less than 1 mm when it needs to be replaced (the general front brake 30,000 km, the rear brake pad 60,000 km need to be replaced).


Brake disc replacement cycle can be determined according to the number of brake disc replacement. The brake disc usually needs to be replaced every two times. But it depends on the results.
