Rotors ARE warped.. can I still use old pads?
I took my centric premium rotors to get cut afters my steering wheel has been shaking whenever I press on the brakes for a while now and the shop says they are warped. The pads have plenty of life left. Am I able to still use the old stoptech street pads (which have plenty of life left) with the new centric premium rotors I'm buying? Should I just go ahead and buy new pads also? The reason this happened was because of stopping on hot rotors while trying to bed in the pads. I live in the middle of the city and literally cant find a long enough low traffic area to do the bed in procedure. I guess I stopped on the hot rotors while bedding them in originally which caused this. I literally only street drive this car and never track or anything. I know everyone says you have to do the bed in procedure but can I just drive normal and let them bed in overtime? I don't want to take a chance on buying new pads and rotors a third time.. Obviously I'm a newb, thanks.

Buy new everything and be done with it.. you shouldnt have had issues bedding them at all---if you generated that much heat during the procedure then you generated way too much and over did it. Take it easy. Brake once or twice and let it go and see what happens

If you dont want to take a risk, then get new pads. Also have the new rotors ground with an on-the-car type brake lathe.

The only pads you really want to bed in with an aggressive procedure are track pads. If you did this with street pads, you most likely over cooked them and then, as you know, pad material got stuck to the rotor when you came to a stop. Any reason you decided to not turn them to get the material off?

same here, if they are street pads LOL. as mentioned above, if you CAN get new ones, may as well. if i remember right, regular pads are really cheap.

Rotors CAN actually warp. Commonly you will notice most vibrations only happen after the rotors get hot, which is brake pads material being transferred to the rotor surface. But rotors can actually become warp. I've machined a LOT of rotors my self to see that the cutting bits will only touch half the surface of the rotor as it spins.
I'd certainly reuse the pads if there is good life left in them. It won't affect anything. The bed in procedure, in my opinion isn't necessity. They will bed in over time on their own. The bed in procedure simply does this quickly, so you can use the pads to their full potential as soon as possible. It's just a street car, don't over think it too much.

I'll say I actually HAVE seen rotors warp, but it was cold water washing over really hot rotors. That's pretty rare. I've just never seen any do it due to getting hot from street pads. Usually the pads go first.
