Hi, I recently brought my rotors to a shop to get them resurfaced and was wondering if I need to do anything special to break them in. I read some sites that if you get new pads and rotors there's this certain procedure you have to follow to break them in. Since getting the rotors resurfaced is essentially like get a new brake rotor is this necessary? Also only the passenger front and back needed resurfacing so I only did those two, is this something I shouldn't be doing. Should I take off the other two and get them resurfaced too. The thickness on all of them are almost the same, but the passenger sides looks like fresh shinny metal.

 

Ideally you should resurface the rotors in pairs according to the axles. It is really a customary practice to do any repair or replacement to the brakes in PAIRS, that is both fronts or both rears. Resurfacing the rotors just on one SIDE of the car could cause uneven braking performance.

Anyhow, the break-in procedure should consist of 8-10 medium effort stops from around 50mph-20mph with a 30-60 second cool down between each stop. Traffic allowing, of course.

 

Not sure about re-surfaced rotors. I dont think you have to. Usually for new rotors yes espeically with brake pads, but to be on the safe side break them in on a long strip of empty road, doesnt hurt to breake them in.
