What is the caliper of the wheel hub?

The following is a detailed explanation of the caliper:

Effect of wheel hub carboplatin

1. Increase braking force: The caliper applies pressure to the brake pad to clamp the brake disc, thereby converting the kinetic energy of the vehicle into heat energy to achieve deceleration or stop.

2. Control the state of the wheel: the caliper can slow down, stop or maintain the stopped state of the moving wheel to ensure the stability and safety of the vehicle.

3. Prevent impurity damage: The design of the caliper also prevents impurity particles from entering its interior, thereby protecting key components such as pistons from damage.

Type of hub caliper

1. Floating caliper: the brake disc of the floating caliper is directly fixed on the wheel hub without floating displacement. The caliper is fixed on the caliper support by the pin or bolt, and a small amount of axial displacement can be made on the pin and bolt. This caliper generally has a brake piston on only one side, and when the brake friction plate contacts the brake disc, the caliper moves under its reaction force, so that the brake friction plate on the other side can also grip the brake disc. 2. Opposite calipers (fixed calipers): Opposite calipers generally adopt a fixed design, and the total number of pistons is generally 2 or more (mostly even). The caliper body is fixed, and brake fluid is distributed to the pistons on both sides through the pipe in the caliper, and at the same time, the brake skin is pushed to contact the brake disc.

Color and performance of wheel calipers

1. Color: Generally speaking, car calipers have three colors, red, yellow and gray. Yellow brake calipers are usually the default choice for ceramic brakes, such as the Porsche GT3 and other powerful cars use yellow calipers. Red calipers are mostly used for high-performance brakes, while gray calipers are widely used in high-performance cars and ordinary models.

2. Performance: The performance of the caliper is closely related to factors such as the number of pistons, material and manufacturing process. As the number of pistons increases (the total area of the pistons becomes larger), the braking force usually increases, but this also takes effect. Depends on the specific design of the caliper and the overall performance of the vehicle.

Hub caliper maintenance and replacement

1. Check: Regularly check the wear of the caliper and the water content of the brake fluid is the key to ensure the normal operation of the brake system. Once it is found that the caliper is seriously worn or the brake fluid moisture content is too high, it should be replaced or repaired in time.

2. Replacement: When replacing the caliper, it is necessary to ensure that the new caliper is compatible with the braking system of the vehicle, and install and adjust it in accordance with professional guidance.
