My '97 cvpi has 85k miles on it and I bought it several weeks ago. This week I was getting a scraping sound coming from the right rear wheel area and found that the pad was worn down to the metal and had scored the rotor. So I replaced all rear pads as well as the right rear rotor (the left rotor looked good). Was it a mistake to only replace one rotor?

The front pads are worn only 50% or less, but the rotors each have a raised edge around outer the 1/8 inch. Is that warping? My guess is the rear pads were original and the front pads had been replaced but nothing was done to the rotos. My plan is to replace both front rotors once the pads wear down, but thought I would ask here to see if anyone has different advice. Thanks.

If there is only light scoring on a rotor, putting a new pad on it will smooth it out. It may shorten the life of the pad, but not by much.

The front with the ridge around the rotor means that is how much it has worn. The pad doesn't cover the edge and so does not wear clear to there.

If the brakes are smooth the rotors are fine.

From other posters here, turning the rotors doesn't do much good. They replace them.

Yup, only reason to turn a rotor would be if your only replacing the pads (perhapse an axle seal failure has saturated the pads with oil...).

As for replaicng only 1 rotor, my personal preference would be to replace them in axle sets to help promote even braking...

replace your rotors in pairs is the way to go. also if you can make sure you replace them with solid cast rotors. you don't want the composit rotors. they are prone to problems
