Brake calipers are a key component of commercial vehicle braking systems. They are primarily used to control the contact between the brake pads and the brake discs, generating friction to decelerate or stop the vehicle. Commercial vehicle brake calipers are heavy-duty, high-performance components designed to manage extreme thermal stress and loads in air or hydraulic disc brake systems, commonly found in trucks, trailers, and buses. Key manufacturers include Meritor, Bendix, ZF(Wabco), and Brembo, offering both new and remanufactured options.

Main Types: Fixed brake calipers, floating brake calipers.
Key Components:
Main Components:
Piston: Responsible for converting brake fluid pressure into mechanical force, pushing the brake pads into contact with the brake disc. Pistons are usually made of cast aluminum alloy or steel, and the surface may be chrome-plated to improve wear resistance and corrosion resistance.
Brake Pad Assembly: Composed of a backing plate and friction pads. The friction pads are the components that directly contact the brake disc to generate friction. Their material needs to have a high coefficient of friction, good wear resistance, and resistance to heat fade.
Caliper Body: As the main structure of the brake caliper, it needs to have sufficient strength and rigidity to withstand the huge forces generated during braking and to provide mounting and guidance for the piston and brake pads.
Materials and Manufacturing Processes:
Material Selection:
Cast Iron: Traditional brake calipers often use ductile iron, which has the advantages of low cost and high strength, but is heavy and has relatively poor corrosion resistance.
Aluminum Alloy: In recent years, aluminum alloy materials have been increasingly used in commercial vehicle brake calipers due to their lightweight advantages. Cast aluminum alloy calipers have a mature manufacturing process and lower cost, while forged aluminum alloy calipers offer higher strength and rigidity, making them suitable for high-performance or weight-sensitive vehicles.

Titanium alloys: Titanium alloys possess high strength, low density, and excellent corrosion resistance, but their higher cost limits their current application in commercial vehicles, primarily focusing on high-end or special-purpose vehicles. Manufacturing Process: Brake caliper manufacturing typically involves casting, forging, machining, and surface treatment. Casting allows for the formation of complex shapes, while forging improves the material’s mechanical properties. Machining is used to precisely machine the various components of the caliper, and surface treatments (such as painting and electroplating) enhance the caliper’s corrosion resistance and appearance.

Our heavy-duty brake calipers are specially developed for commercial vehicles under long-distance, high-load and harsh working conditions.
Adopting high-strength material and precision machining, they ensure stable, safe and consistent braking performance.
