General description The Pair Rear Brake Caliper is designed for the Toyota Avensis T27 models from 2008 to 2016. It functions as a clamp on the wheel’s rotor, stopping the wheel from turning when the brakes are applied. Inside each caliper, there are metal plates known as brake pads. When the brake pedal is pressed, brake fluid creates pressure on the pistons in the caliper, forcing the pads against the brake rotor to slow down the vehicle.
