replaced brake rotors

just wanted to chime in here,

I had a dealer do my rear brakes couple of months back and a m8's shop did my fronts last week, (with OEM parts) car is on 107k. the rotors where trashed, the inside had big grooves in them BUT the pads where fine had LOADS of depth.

Any idea why this happens , I mean hardly any wear on the pads ? but rotors trashed ?

Sometimes different models have their own specific issues that don't happen on other series/models so...you have a Canadian 1 series? Looks like you've had it a while, original owner?
So assuming brake issues are not common on your model the reasons could be a poorly done previous brake job or a rock got stuck in there. Do you have info on the previous brake job?

hey dude,
car was previous demo, bought it on 22k, essentially new
never did a brake job till recently, I did keep an eye on things every tire change, and the pads always looked good, only summer the guy said, there is a lot of wear on the inside,
not untill we removed the rotors last week did we see how bad

Than I'm going with option A, a previously poorly done brake job. At 22k they probably just put new pads on and didn't even remove the rotors, which is a big no-no, they must at least be resurfaced (and verify thickness) when replacing pads. Unfortunately you can't get a good look at the back side of the rotor without removing it because of the dust shield (protection plate as BMW typically calls it).

I think the very minimum brake change interval is 30k, can't see a brake job at 22k especially a demo, unless it was being thrashed by all who drove it ?
It would also be covered under the original BMW w'tee, can't see them skimping on a brake job especially when claiming it back from BMW
TBH, between 22k at 107k there was hardly any wear on the pads (fronts certainly) a bit more on the rear, but, I don't know really weird.

oh just to re-ask, why is it bad to just do pads,

I thought usually this is just a "gimme more money" thing

I''ve done numerous brake jobs including the 944 and never had a problem.

Can you expand on why you should not just do pads ? Unless of course the rotors are not worn or warped ?

There is nothing wrong with only replacing the pads, but to reuse the old rotors they should be resurfaced and the thickness verified. Pads wear a groove in the rotor and a new set of pads ain't gonna fix that.
You still haven't verified, is that a 1 series? And you think it was always driven by a grandma before you bought it?
