The serviceability of front brake rotors is determined by several factors. All rotors will show some scoring or grooves without any significant reduction in brake function. If the rotors have significant grooves over ten-thousandths of an inch, they are good candidates for replacement. Another factor to be considered is if they are worn below recommended factory specifications. This is the most common reason for replacement. The minimal thickness is marked on the rotor close to the center, and written in tiny increments, so a micrometer is necessary to measure the thickness. There are two types of rotors, and the procedure is somewhat different for each type. The first type is used mostly on front-wheel-drive vehicles, where the rotor comes off as one single unit. The second is on trucks and older rear-wheel-drive vehicles. This type of rotor houses the front wheel bearings. Raise the vehicle and support on jack stands. Remove the wheels. Place the drip pan under the caliper. Loosen th
