Brake Caliper 

A part that performs the function of compressing the friction pad on both sides of the disk on a disk brake.

A device that holds the front wheel brake by contacting the pad of the motor vehicle with the disk brake, which is operated by hydraulic pressure. It surrounds the front wheel brake disk. When seen through the hole on the front wheel, variously painted calipers are seen.


 



* Principle of Operation

When the master cylinder receives hydraulic pressure as the brake operates, the brake oil inside the cylinder causes hydraulic pressure to work as a force left and right inside the cylinder. The force working towards the left compresses the inner pad to the disk by sliding the piston and the force working towards the right slides the housing towards the right. This compresses the outer pad to the disk to simultaneously cause friction to the inner pad.

 

* Recovery of Disassembly

Based on the recovery of the seal piston, the piston returns to its original state, and the inner pad maintains a gap with the disk by the disk rotation. Simultaneously, the outer pad disassembles a compression force by the housing sliding force to maintain a gap with the disk, which removes any residual torque.

 

* Types of Calipers

First, the floating form, where the pad compressing the rotor while the caliper itself slides, and a piston is on one side.

Second, the opposed form, where a completely fixed caliper is on both sides of the piston to compress the rotor.

Third, the rear caliper form, where the method of operation is identical to the floating form when in the standard brake state
