4 Wheel Cylinder Set Here you can find newly manufactured Wheel Cylinders for your American Classic or Muscle car. These cylinders have newly casted bodies and contain brand new components. In some cases the cylinders we sell are of an improved design, so if you are worried about judging, please inquire about your parts before ordering. Wheel cylinders should be replaced whenever a brake overhaul is performed, to ensure proper brake pressure at each wheel. We also offer master cylinders for many applications! Please let us know the exact year, model, and engine type of your car so we can send out the correct type and appropriate number of cylinders.
