4 Pot Brake Kit 285*24mm Dragon Disc Kit For Mercedes Smart W453

The difference between caliper and brake pad is that the brake pad is squeezed on the brake disc or brake drum to produce friction during braking, so as to achieve the purpose of vehicle deceleration and braking. The caliper clamps the brake disc when stepping on the brake to slow down or stop.

What is the difference between calipers and brake pads

The brake caliper and brake pad are the terminal executive parts of the brake, so the modification of the brake caliper and brake pad can play an important role in improving the braking force.

Refitting and replacing a set of large, multi piston brake calipers can directly improve the braking performance. If the brake caliper becomes larger, the total area of the brake pad will be larger accordingly; The more brake caliper pistons, the more uniform the pressure and friction temperature applied to the brake pads will be, and the total area of the piston can be increased. Of course, the braking efficiency will be improved.

Modification of high-performance brake pads the friction of brake pads is the most important, High performance brake pads are mostly made of metal (cast iron, aluminum alloy) and carbon fiber are the main raw materials. The performance of brake pads mainly depends on the material formula, because the selection of brake pads requires material information. It is very particular to buy brake pads. Some car owners use the brake pads of pure racing cars, but they get worse braking effect than the brake pads of the original car. The reason is that the temperature of brake pads is applicable, and ordinary vehicles can't reach the standard of racing at all Due to the high temperature of car braking, the pure racing brake pad can not give full play to its high braking force at high temperature, so it can not achieve the desired effect

What materials are pistons made of?

Material: titanium alloy, aluminum alloy, iron; Influencing factors: heat dissipation and oxidation. The piston is the intermediate medium for the brake oil to push the brake pad. When the caliper works, the brake pad will produce high temperature due to friction. Under the conduction of the piston, the brake oil temperature will rise slowly. Brake oil that exceeds the operating temperature will lose its conductivity.

Therefore, the material with faster heat dissipation can provide more stable braking performance. The material also affects the performance of the piston. For example, a rusty piston will produce resistance when moving. The common materials of pistons from high to low are titanium alloy, aluminum alloy and iron.

The caliper can also be called the brake wheel cylinder. There are many pistons inside the caliper. The function of the caliper is to push the brake pads to clamp the brake disc, so that the car can slow down. After the brake pads clamp the brake disc, kinetic energy can be converted into heat energy. The braking system is a very important system in the automobile. The braking system is related to the driving stability and driving safety factor of the automobile. The key components of the brake system include vacuum booster pump, brake master cylinder, brake wheel cylinder, brake pad and brake disc. Brake pads and brake discs are basically vulnerable parts that need to be replaced regularly. With the addition of vehicle driving stroke, brake pads and brake discs will basically be worn continuously. After the brake pads and discs are worn to a certain extent, they need to be replaced. If they are not replaced, the braking distance will be affected. After the driver depresses the brake pedal, the brake master cylinder can push the brake wheel cylinder through the brake fluid. At this time, the brake wheel cylinder can push the brake pad to clamp the brake disc. The vacuum booster pump supplies power. The vacuum booster pump allows the driver to easily step on the brake pedal. The brake fluid in the brake system needs to be replaced regularly. If it is not replaced for a long time, it will affect the braking force and braking distance. Brake fluid is a kind of fluid that absorbs water easily. When the water content of brake fluid reaches 3%, it needs to be replaced. After replacing the brake fluid, it is necessary to drain the air in the brake system pipeline, otherwise the braking force and braking distance may be affected.
