REPRODUCTION. You are purchasing a pair of rear wheel cylinders. Please note that these have a 1-inch diameter piston. If you currently have a larger size piston in your vehicle, you would need to replace BOTH wheel cylinders. Please note it is not advised to switch to a smaller size wheel cylinder as it could slightly decrease the stopping power of the rear brakes.
