Construction of a Brake Caliper

The brake caliper is a sturdy component typically made of high-quality materials to withstand the forces and heat generated during braking. It consists of several key components, including: 

  • Caliper Housing: The caliper's main body houses the other components and encloses the brake pads and rotor.
  • Pistons: These are cylindrical components located inside the caliper housing. When hydraulic pressure is applied, the pistons extend outward to push the brake pads against the rotor.
  • Seals and Dust Boots: These ensure a tight and reliable seal around the pistons, protecting them from dirt and contaminants. Proper seals are vital to prevent brake fluid leaks and maintain hydraulic pressure.
  • Brake Pad Clips: These clips securely hold the brake pads within the caliper.
  • Bleeder Screw: A small screw used to release air and excess brake fluid from the caliper during brake bleeding procedures.

In addition to these components, modern brake calipers often include advanced features, such as anti-rattle clips and electronic brake pad wear sensors, to enhance performance and safety.
