1: brake pads, generally by steel plate bonding, heat insulation layer and the friction blocks, the heat insulation layer is composed
of no heat transfer material, purpose is to heat insulation (overheating to brake system destroyed).Friction block is composed of
friction materials, adhesives, squeezed when the brake on the brake disc or drum brake friction, so as to achieve the purpose of the
vehicle deceleration braking.Because of friction, the friction piece will gradually be wear and tear.
2: the brake disc, in simple terms, is a round plate, it is also as the car travels.Brake pad friction block brake calipers (mentioned
above) in the brake disc and brake force, clips brake disc brake is it to slow down or stop.
What is the difference between brake pads and brake discs? Bicycle brake principle we all know, as long as the hand to knead brake,
2 pieces of brake wallet bicycle wheels, so as to achieve the goal of bicycle brakes.Similarly, automobile brake system is relatively
complex, but the principles are the same, when you are in the process of driving, the foot brake of this action is equal to the cyclist
to knead brake.Thus auto brake shoe drive brake pads, turns on the brake disc, produce friction,braking effect.So, they are the most
simple difference is that the brake disc is the same as the wheel in turn, but the brake pads are still forever.
