When you state that the rotors were replaced with grooved rotors, do you mean slotted? When I think of a grooved rotor I think of a rotor that has grooves caused by a worn pad.

"do you mean slotted?"
 
These were shorter, wider, and curved. I'm guessing they were cast in, then remained after machining.

Mini Cooper 2005 - Break issue by luciep

The Mini Cooper dealer installed new breaks & discs on my 2005 Mini Cooper last fall – 54,000 km. Original problem was I had vibration in the front left side when braking; they looked at the breaks and said they were finished and changed them with new ones (front & back).
 
I now have 58,000 km and the problem started again; they say it is because I do not do lots of mileage and it is normal. This car is not my 1st one and it does not seem “normal” to me. I read on some sites that it is a known problem with Mini breaks (rotor does not wear evenly). Is there a solution?

Ask the dealer to explain to you with a straight face and not bursting out laughing how brake rotors warp by NOT driving the car. So their position is that Minis will normally go through brake rotors every 4000 km?
 
You have to demand that they warranty their work as they are supposed to.

Well, if they over-torque the wheel bolts really badly and induce warpage that way, the rotors would pulsate in short order, driven or not.

Good point---that's an "explanation" for rotor warp in 2400 miles but not the one the dealer is likely to give.
 
I suppose you could take the MINI racing, get the rotors red hot and then drive through a puddle of ice and slush---that would do it.

Of course the dealer would never admit to doing anything wrong, now would they? It is easier to blame the customer.
 
No, torque sticks are not a good substitute for a proper torque wrench. And no, using a torque wrench after tightening the lug nuts with an air wrench set to 650 lb-ft is not correct either. A work order that says "No air tools for tightening" and "customer waiting" may induce some dealerships to do the right thing, sometimes.
 
I think that if the lug nuts are properly torqued, and if the rotor has been seated properly on the hub after cleaning any corrosion (like they are supposed to be done) then it will take a lot of red hot racing and driving through icy puddles to warp them.

The factory rotors on some brands are prone to warpage. Is the Mini? It may be worthwhile to check aftermarket rotors, but don't let the dealer off the hook. I put aftermarket on our Avalon. So far, so good.

Sure some cars are under-engineered, but "prone" to warpage is not the same as warpage in 2400 miles, seems to me. I never heard of warpage on the MINI at any rate...it's a very light car and it has fairly beefy rotors. This makes little sense to me that warpage would plague a car of this specification----unless the dealer is putting on Mickey Mouse rotors, I don't know.
