They are part of the disc brake system, which is widely used in modern vehicles due to its superior performance compared to drum brakes. Functionally, the brake caliper houses the brake pads and squeezes them against the brake rotor when you press the brake pedal. This action creates friction, which slows down the rotation of the wheels and brings the vehicle to a stop. Brake calipers are essential for converting the hydraulic pressure generated when you press the brake pedal into mechanical force to stop the vehicle. There are two main types of brake calipers: floating calipers and fixed calipers. Floating calipers are simpler in design and consist of a single piston that moves back and forth to apply pressure on the brake pads. Fixed calipers, on the other hand, have pistons on both sides of the rotor and provide more even pressure distribution, resulting in better braking performance. Fixed calipers are commonly found on high-performance vehicles due to their superior braking capabilities. Brake calipers are typically made from materials that can withstand high temperatures and resist corrosion, such as aluminum or steel. Some calipers are even made from carbon fiber for lightweight and high-performance applications. It's important to maintain and inspect your brake calipers regularly to ensure they are functioning properly. Signs of a faulty caliper include uneven brake pad wear, leaking brake fluid, or a spongy brake pedal. Any of these symptoms could indicate a problem with the caliper that needs to be addressed promptly to ensure safe driving conditions. In conclusion, brake calipers are a critical component of a vehicle's braking system, responsible for converting hydraulic pressure into mechanical force to slow down and stop the vehicle. Understanding how brake calipers work and recognizing the signs of potential issues can help ensure your safety on the road. Regular maintenance and inspection of your vehicle's braking system, including the calipers, are essential for optimal performance and safety.
