I have gotten three or more sets of pads on one set of rotors. I change pads when the pads are equal the backing. In other words I change at about one third of the pad left. Obviously the width is important as well.
I was curious if any one knows how to extract the front rotors frome a 93 124? I have every thing off but the rotor is froze to the hub. I tried hammering and penetrating oil with no luck. Is there a specific technique to
realese stuck rotors? Do you hemmer from the back only? Any guidence would help a lot.
