I have a 95 corolla that has 134k and the rotors have never been changed. I had personally just changed the pads for the third time of it's existence because it had a squeal. It still has the squeal even with the new pads and it occurs during warm weather and after the car has been driven around for about 15 minutes in city driving. The squeal goes away as I start applying pressure to the brake pedal. Is it the rotor (has never been turned)? I do not experience any pulsing pedal. Where can I put some anti squeal grease and does it work? What is the most common source of the squeal? Thanks for your opinion!
