A friend with a 993 just told me that he had to have new surfaces put on his rotors. He said the rotors were not "surfaced" but that some additional metal material was somehow bonded on to the rotors. Really? Is that what they do now? No surfacing until past tolerance, and then simply replacing the entire rotor?

He also commented that he has been very unhappy with the brakes since this was done by the dealer.

 

Your comment is Confusing. If a rotor is good and can be resurfaced (cut to within minimum specs) it can be used. If it is out of spec after it is cut (resurfaced) then get new ones. I've never heard of what your friend has experieced. I don't know of nor have I heard of any bonding capability to build rotors back to spec.

 

You and me both! That's why I posted the question. Seems completely contrary to anything I would expect to go on with safe braking. I mean, trust some compound to keep that surface attached after constant repeated cycles of disparate heating, cooling, and warping? Just seems like a no brainer.

Yeh - I'm sure they took them down to the lab and used metal vapor deposition...

Friend needs to write a nice Email to the delaer asking them to say what they did - that will get the lie in permanent form...

 

Yeah. You know, either that or my friend had a brain cloud on what "resurfacing" means.
