An Overview On Car Brake Calipers

in Brake

The brakes systems are essential for a car, and the calipers are one of the most important devices in the system. They apply the necessary power to slow down the car or to stop it. They should always be in good condition and repairing worn out ones are essential for good driving. Inefficient calipers are unsafe for driving.


The calipers serve a very big role in the brake system. These small, box-like, rectangular devices are contained in the wheel housing. They are set near the rotary metal disk that is connected to the wheels. They function through a hydraulic system and the brake fluids transfer the pressure needed to move the calipers. In a standard brake caliper, there are metal pipes that are found on the interior and exterior of the rotor. The plates have brake pads and these make the physical contact for the calipers and rotors. When the pedal is pressed, the brake fluid goes through a master cylinder and it is linked on the piston that houses the calipers. The piston presses the pads and the pads are forced to the rotors. The result is the car will start slowing down.


These disk brakes became commercial in the automobile industry around the 1950s, they are great improvements over the drum brakes which could easily overheat and deteriorate in performance in a very short period of time. Almost all cars use the disc brakes but some use the drum brakes on the rear axle.


The floating calipers utilize hydraulic piston along the rotor inboard side. These move in and out when the pedal is pressed. The fixed calipers have pistons that are set on both the sides of the rotor and the pressure is applied directly from the 2 sides making the operation much smoother.


The pads usually wear down because of the constant friction and so it is essential to check the pads whenever they are starting to make noise. The brake system should always be checked for wear and tear all the time for safe driving.
