What are brake calipers?

January 15, 2023

Brake calipers are an essential component of a vehicle's braking system. They are responsible for applying pressure to the brake pads, which in turn, slows down or stops the rotation of the wheels. In this blog post, we will discuss the different types of brake calipers and their functions.

There are two main types of brake calipers: fixed and floating. Fixed brake calipers have pistons on one side of the caliper, while floating calipers have pistons on both sides. Fixed calipers are typically found on the front wheels of a vehicle, while floating calipers are typically found on the rear wheels.

Fixed brake caliper

Fixed brake calipers are the most basic type of caliper. They have one or more pistons that push the brake pads against the rotor, slowing or stopping the wheel's rotation. These calipers are typically found on the front wheels of a vehicle.

Floating brake calipers

Floating brake calipers, on the other hand, have pistons on both sides of the caliper. This allows for more even pressure distribution on the brake pads, leading to better braking performance. Additionally, floating calipers have the ability to move with the rotor, which allows for better heat dissipation and reduces the risk of warping. These calipers are typically found on the rear wheels of a vehicle.

Sliding caliper

Another type of brake caliper is a sliding caliper. A sliding caliper is similar to a floating caliper but the caliper has one or more pistons on one side and the caliper housing slides on a guide pin. This design allows the caliper to move in and out as the brake pads wear down. This type of caliper is typically found on the rear wheels of a vehicle.

Regardless of the type of brake caliper, they all perform the same basic function: applying pressure to the brake pads to slow or stop the rotation of the wheels. Regular maintenance and inspection of brake calipers is important to ensure safe and effective braking performance. If you notice any issues with your brake calipers, such as a stuck piston or leakage, it's important to have them inspected and repaired by a professional mechanic.

In conclusion, brake calipers are an essential component of a vehicle's braking system. They come in different types such as fixed, floating and sliding, each with its own unique design and functions. It is important to maintain and regularly inspect your brake calipers to ensure safe and effective braking performance. If you notice any issues with your brake calipers, it's best to have them inspected by a professional mechanic.
