with new rotors always get new pads to seat with the rotors. i recommend getting the rotors in sets, either both fronts or both rears.Originally Posted by L0veZHP
you might need to use a micrometer on the rotors and see if they are at their minimum thickness. If you see deep grooves, gouges or overheating marks I would replace them.

Just to round this out....the min rotor thickness is stamped on the rotor hat. A pic for you my friend.
And a good bedding procedure can be followed below.....under technical....then how to bed brakes....

All these fellas are right.

For my car the brake rotor wells where the E-brake shoes contact have glazed up and are very smooth so that the ebrake shoes can't grab onto much. I took my rotors off and used sandpaper to rough it up at much as possible with not much success. So the only solution is to get new rear brake rotors. For now I don't part on super steep inclines/declines...haha. And ALWAYS park your car in gear!

You can still get the performance rears for cheap.....

Can someone tell me the minimum rotor thickness of the stock rear rotors? I can see the minimum thickness number stamped on my front rotors (I think it's 23.4mm or 24.3mm) and my front rotors are comfortably above this number. But I cannot find the stamped number on my rear rotors, possibly hidden by corrosion.

Minimum thickness is usually stamped on the rotor somewhere.

Yes, but I can't find the stamping on my rear rotors. Do you happen to know what it is for the ZHP rear rotors?
