There are primarily two types of brake calipers - fixed and floating. Fixed calipers are mounted securely to the axle and do not move. In contrast, floating calipers slide on guide pins, allowing only one of the caliper's pistons to move.

Brake calipers are typically crafted from lightweight and durable materials like aluminum or cast iron. These materials provide the required strength and heat dissipation capabilities crucial for optimal braking performance.

Brake calipers have a longer lifespan compared to brake pads and rotors, typically lasting several years or even longer. Regular inspections of your braking system, including the calipers, will help ensure they are functioning optimally and assist you in determining when replacement might be necessary.

There are some telltale signs that may indicate your brake calipers need attention. If you notice decreased braking efficiency, uneven wear on the brake pads, or any fluid leaks around the caliper, prompt inspection by a qualified mechanic is recommended.
