Each wheel of the car has a specified caliper and rotor for halting it at the sudden situation on the road. When the car is moving, you will notice the rotor is spinning. If you want to slow down the car by pressing the brake pedal, the brake calipers and pads produce friction with the rotors to slow down it. Due to many reasons, the brake caliper is sticking, so go through the slides to determine the sticking brake caliper of the car.
