Modification and function of brake caliper and brake pad

Brake calipers and brake pads are the terminal executive parts of braking. Therefore, the modification of brake calipers and brake pads can have an impact on the improvement of braking force. Although it is very effective, there are still some precautions in the modification process. Let's have a look.

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.

Brake caliper

The modified brake calipers are divided into non original and original. Non original brake calipers are almost all racing products. The multi piston design is adopted, which must be matched with the special adapter support commonly known as "bridge" during installation. In addition to the large pressure area of the piston, the weight of this kind of products is particularly light, which can reduce the load of the suspension and accelerate the activity speed of the suspension. If used with a brake disc with a larger diameter, the light caliper can offset the increased weight of the brake disc. The original products usually adopt the design of a larger diameter or multiple caliper pistons.

Brake pad

Modification of high-performance brake pads the friction of brake pads is the most important. Most high-performance brake pads are made of metal (cast iron, aluminum alloy) and carbon fiber. The performance of brake pads mainly depends on the formulation of materials, because the selection of brake pads requires material information. Buying brake pads is very particular. 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 the temperature problem of the brake pads. Ordinary vehicles simply can't reach the high temperature of racing car braking, so the brake pads of pure racing cars can't exert its high braking force at high temperature, so they can't achieve the due effect.

When selecting high-performance brake pads, be careful not to pay too much attention to ultra-high temperature and friction coefficient. If the friction coefficient is too high, the braking action of the vehicle when driving at a slow speed will become too sensitive. Each touch of the pedal will make the passengers on the vehicle look up and close back. At the same time, it will also cause excessive wear of the brake disc and affect the service life. The high-temperature resistant brake pad can not play a high-performance braking force at low temperature, and the effect will be greatly reduced. Therefore, the modification of brake caliper and brake pad varies from vehicle to vehicle and from driving habits.
