Before the introduction of the euro, francs were also used in France, Belgium and Luxembourg, while Andorra and Monaco accepted the French franc as legal tender (Monegasque franc).
Inside the caliper is a brake pad, a small block of friction material backed with a metal plate. When you step on your brake pedal, pistons inside the caliper cause it to apply pressure to the brake pad which squeezes the rotor, causing the car to slow or stop.
A caliper is part of the disc brake system. When you press the brake pedal, the brake fluid flows from the master cylinder to the calipers. Brake fluid then applies pressure on the piston inside the caliper, pushing the brake pads against the rotors to slow/stop your car.A car can have either 2 or 4 calipers.If the car has rotors on all four tires, then it will have four calipers. If the car has two rotors and two drums, then it will come with two calipers in front. The calipers can become contaminated, rusty, and start to leak brake fluid.Brake calipers absorb a lot of heat generated from the braking system.f the car has rotors on all four tires, then it will have four calipers.
