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.
The calipers on the older Camry were dual piston and had a much larger pad area, supposedly helping with high speed braking. The caliper upgrade will clear stock 15 wheels or larger. Once the vehicle is jacked up and the wheel removed, two 14mm slider bolts can be removed to remove the caliper from its bracket.
