Well my brakes were shuddering when braking from 60mph and up. I brought it to mitsubishi today and they just resurfaced it without changing the pads. I suggested them changing the pads too...but they didn't. Well it brakes fine now from 60mph and up...should I break them in like I had new pads or not?

 

Yup, its best to be gentle on them for a little while. When they resurfaced them, the transfer film from the pads was removed from the rotor. If you just crank on them to start with, pad material can buildup and possible glaze over on the clean surface. So, brake (no pun intended) them in easily as you would a new set of brakes
