It depends on whether the types of front and rear brake pads used in the car are the same.
There are two types of brakes used in general cars. One is a disc brake and the other is a drum brake.
There are more disc brakes generally used in the front wheels. Some cars in the rear wheel use disc brakes, and some cars use drum brakes.If the front and rear wheels use disc brakes, the brake pads will be in the same form, but the size will be different.If the disc brakes used in the front wheels and the drum brakes used in the rear wheels, the brake pads are completely different in form.
All the braking effects are decisive for the brake pads. The brake pads are generally composed of steel plates, bonded thermal insulation layers and friction blocks. The thermal insulation layer is composed of materials that do not transfer heat, and the purpose is to insulate. The friction block is composed of a friction material and an adhesive, and is squeezed on the brake disc or the brake drum to generate friction when braking, thereby achieving the purpose of decelerating the brake of the vehicle. Due to the friction, the friction blocks are gradually worn out, and generally the lower the cost, the faster the brake pads wear. After the friction material is used, the brake pads should be replaced in time, otherwise the steel plate and the brake disc will be in direct contact, eventually losing the braking effect and damaging the brake disc.
