If you have 14 inch wheels and the 14 inch are standard then you have a single piston. If the car came with 15 inch wheels then you have a double piston system. Most of the cars came with 14 inch, check on door sticker and see what size rims came with the car originally. If 14, then one piston, if 15 inch wheels then it has 2 pistons.
