Brake Calipers are located on each wheel of the car and work to squeeze the brake pads against the rotors by hydraulic pressure of the brake caliper pistons. The brake calipers slow the spin of the wheel and get the vehicle to reduce its speed once the driver presses the brake pedal. The brake caliper is made of cast iron but can be also made of steel, stainless steel or aluminum. Production cycle includes milling, drilling, reaming, slotting and threading operations.
