I just replaced a friends rear disc brakes (98 v-6). He had worn them down to metal and both rotors had to be replaced. So we got new pads and rotors everything is fine. A few days later we start to hear a harsh rubbing sound while the car was rolling, if you step on the brake a little bit the noise goes away. So we got home and i started to take the rear passenger tire off and the bolts are HOT!! i checked the other side and there were warm but you could hold them in your hand. the passenger side couldnt be touch. Well, we got them off with the wrench pulled the wheel off and I ran my finger across the rotor (yeah I knw not too bright) it blistered my finger. They must have been rubbing the whole time. SO I am assuming the rotor is warp but cant figure out why. They were both brand new. the driver side seems fine.. could the caliper be done in??? I thought if they went bad they usually locked in place. Both went in with no problems.... anyone got any suggestions???
