Brake pads in automotive brake systems

Brake pads are also called brake skins. In the braking system of a car, brake pads are the most critical safety parts, and all brake effects are decisive for brake pads, so it is said that good brake pads are the protector of people and cars.

brake pads

Brake pads generally consist of steel plate, adhesive heat insulation layer and friction block, where the heat insulation layer is composed of materials that do not transfer heat, and the purpose is heat insulation.

The friction block is composed of friction material and adhesive, which is squeezed on the brake disc or drum to produce friction when braking, so as to achieve the purpose of vehicle deceleration and braking.

As a result of friction, the friction block will gradually be worn out, and generally speaking, the lower the cost of the brake pad, the faster it will wear out.

When the friction material is used up, the brake pads should be replaced in time, otherwise, the steel plate and brake disc will be in direct contact, which will eventually lose the braking effect and damage the brake disc.

There are brake pads for disc brakes, brake shoes for drum brakes, and lining pads for large trucks.

In terms of formulation technology, there are: semi-metallic brake pads, metal less brake pads, NAO formulation brake pads, ceramic brake pads, NAO ceramic brake pads

The brake drums are equipped with brake shoes, but generally people call brake pads brake pads and brake shoes, so the term “disc brake pads” is used to specify the brake pads installed on disc brakes, not brake discs.
