What is a brake caliper?

Brake calipers are an important part of a vehicle's braking system, located near the wheels and responsible for managing the interaction between the brake pads and discs. This interaction creates friction that slows or stops the vehicle's movement. Brake calipers play a vital role in ensuring efficient braking and safe driving of modern cars and trucks.

Why are brake calipers important? Proper design and performance of brake calipers is critical to a vehicle's overall braking efficiency and safety. Brake calipers must be maintained and inspected regularly to ensure they are working properly as this is vital to vehicle safety. Insufficient brake calipers will significantly reduce braking performance, thereby endangering driving safety. Therefore, regular inspection of brake calipers and pads to identify leaks, excessive wear, or damage is critical to maintaining the reliability of your braking system.

The function of car calipers:

◆ Brake calipers are devices designed to slow down, stop, or keep moving wheels in a stationary position. They are primarily used in vehicles equipped with disc brake systems.

◆ In a car's disc brake system, various components work together: a brake oil pump, a brake disc connected to the wheels, and a brake caliper positioned on the disc. When the brakes are applied, high-pressure brake oil is pumped, pushing the piston inside the caliper. This exerts pressure on the brake pads, causing them to press against the brake disc, resulting in the desired braking effect.

◆ Disc brakes can be categorized into two types: ordinary disc brakes and ventilated disc brakes. Ventilated disc brakes have a gap between two brake discs, allowing air to flow through. Some ventilated discs feature circular ventilation holes, while others have ventilation slots or pre-made rectangular ventilation holes on the disc surface.

◆ Ventilated disc brakes harness the airflow, providing superior cooling and heating effects compared to ordinary disc brakes. The main advantages of disc brakes include their ability to rapidly bring a vehicle to a stop, superior heat dissipation compared to drum brakes, and consistent braking efficiency, which makes them compatible with advanced electronic systems like anti-lock braking systems (ABS).
