The brake caliper is an essential part of a vehicle's braking system, and its primary function is to stop or slow the wheels by applying pressure to the brake discs. At SDT brakes, we will explain in detail what a brake caliper is, how it works and how it is used in the context of your car's braking system.

Brake caliper: what is it and how to use it?
What is a brake caliper?
A brake caliper is a crucial component of a car's disc brake system. Its design resembles a clamp or caliper that surrounds a brake disc, also known as a rotor. Brake calipers are responsible for applying the pressure necessary to stop or slow the wheels in motion by generating friction against the brake discs.
Function of the brake caliper
The primary function of the brake caliper is to convert the kinetic energy of the wheels into heat through the friction generated by the brake pads. This heat dissipates the kinetic energy and stops the wheel from moving. Here is how it works in detail:
- Hydraulic pressure: the vehicle's hydraulic brake system is responsible for sending brake fluid under pressure to the brake caliper. Hydraulic pressure is generated by the brake pedal and transferred through the brake lines.
- Brake pads: Inside the brake caliper is a series of brake pads. These pads are lined with high-strength friction material and are in constant contact with the brake discs.
- Friction generation: When the brake pedal is applied, hydraulic pressure pushes the brake pads towards the brake disc. This contact generates friction, which converts the kinetic energy of the wheels into heat.
- Stopping or slowing: the friction generated by the brake pads slows the wheels down or stops them completely, depending on the amount of pressure applied to the brake pedal.
How to use a brake caliper?
Using a brake caliper is relatively simple, but it is important to do it properly to ensure safe and effective braking. Here are the basic steps for using a brake caliper:
- Normal driving: when driving your car, keep your feet off the brake pedal and allow the vehicle to move forward or coast normally.
- Braking: whenever you need to slow down or stop the car, gradually apply pressure to the brake pedal with your foot.
- Progressive pressure: pressure on the brake pedal should be applied progressively and steadily. Avoid abrupt braking or pedal shocks.
- Speed control: modulate brake pedal pressure as necessary to control the speed of your vehicle.
- Emergency braking: In emergency braking situations, apply firm, quick pressure to the brake pedal. The brake system should respond to stop the vehicle as quickly as possible.
- Maintenance: Be sure to perform regular maintenance on the brake system, including checking brake pads and calipers, to ensure safe and efficient braking.
