Brake pistons are actuated by either fluid or air pressure. As you depress the brake pedal, the increase in pressure in the brake line expands the flexible end of the brake line, located in the brake caliper. As the pressure increases, it forces the brake piston to move within the caliper, putting pressure on the brake disk, and slowing its rotation, slowing the vehicle. As the brake pedal is released, it creates a vacuum in the system that causes the piston to relax and free the disk to spin again,

How does the Brake Piston Cube work?
The Brake Piston Cube is a cube-shaped tool used to retract brake caliper pistons in vehicles when changing brake pads. Its design allows it to fit into the caliper housing and apply even pressure to retract the pistons back into the caliper, facilitating easier brake pad replacement. By turning the Brake Piston Cube, the pistons are compressed uniformly without damaging the caliper or seals.
