[About Brake Caliper Fastening] It is the type of defective brake calipers. When you step on the brake pedal, the hydraulic piston of the brake caliper is extruded, and when you release the brake pedal, the twisted rubber will return to its original position. If dirt or rust adhere to a piston, the rubber (piston seal) movement becomes dull or worse, the brake pad will always be pressed into the brake rotor. These conditions are called brake caliper adhesion. If you leave the brake caliper firmly in place, you must not touch it inadvertently as the brakes are left on while driving and the brake area may be very hot. It is also very dangerous because the bond causes only one side of the brake to be locked and the brake is in a working condition (To prevent accidents) This is a brake caliper that causes dirt and water to be splashed, so it is much faster than off-road use. The brake caliper also wants to maintain to prevent collisions and accidents (Firmly compatible with off-roads) Of
