Dumb question about brakes...
I have an 07 Cooper S and it is time to replace the brake pads. So here's the dumb question: is it a must to replace the rotors if there seems to be no problem with them? I bought some EBC pads and the sensors also. I was going to tackle the job this weekend but was told that I need to replace the rotors when changing pads. I guess I'm just an old fart and remember replacing many pads without changing rotors as long as there was not damage to them. Thanks for your help.

It's always a good rule of thumb to replace rotors with pads.
First, rotors have become a consumable (where they're a throw away item) as they are produced thin to specifications...
Second, they are case-harden and will rip apart tooling if turned down.
Thirdly, and probably most important, the new pad surface is considered smooth and flat.
The existing (used) rotor isn't as it has scoring ridges, hills, and valleys due to wear and the new pad won't make 100% contact with the rotor.
Plus, it's a serious safety item as you want your pads to grab instantly versus trying to compress around ridges and rotor protrusions.
Bottom line: grab new rotors; they are cheap.

I believe as long as the rotors aren't gouged, pitted, or scorched you should be ok. Some places won't change pads w/o replacing rotors but I really think alot of that is $$$$$$. There are still some places that will turn them as well.
I did change mine when time came but I also went with a better rotor and the EBC redstuff pads. Zimmerman cross drilled rotors.

I order most parts like this from www.WayMotorWorks.com
He's out of Atlanta. Shipping isn't too bad and he's quick.
You don't have to buy the drilled rotors either. The plain rotors are cheaper priced.
And yes, I'm way down by Gulf Shores and love it.
Belong to the Sunshine Mini Club (Fl. Panhandle group). Great bunch of folks.
In fact, this Sunday we're having a 'Cram the Ferry' rally. Meet, eat, ferry ride from Dauhin Isl. to Fort Morgan with about 30 Mini's. Looking forward to it.

The rotors are held on with a Torx screw which can be a little tricky if rusted. But otherwise these should come right off.
Do a search on this subject in the DIY forums; lots of good info there.

The parts are the same and I have not had a problem with them yet. Like I posted before make sure that you cross reference the part # with the website of the product you intend to buy so that you know you are getting the right part.

I ended up ordering Molly's Akebono Euro Ceramic Pads from TireRack and Zimmermann Brake Rotors from WMW today!! I called PartsGeek but got a recording and God Awful music, I was calling on my Lunch Hour and didn't have tim to wait, so I gave a fellow NAMer my business!!
OBC is showing 2600mi. for Front Brakes and with MINI Run Season fast approaching I wanted to be prepared!!
All getting installed @ MINI of Portland (their NEW Location) on February 20h, 4yrs. and 1 day from ordering my beloved MINI!! I am also going to have the Auto Tranny Fluid Flushed while she's there.

Most European vehicles come with softer rotors that wear with the brake pads, makes for great breaking power but more expensive when it's time to replace the pads and rotors. With most American and Japanese vehicles, the rotors are good for the life of the car and as long as they're not damaged they just get resurfaced each time you change the brakes. This makes for cheap brake jobs but not so good braking power.

And don't forget some American cars are retarded. My old Ford F150 being one of them. Don't think those front rotors are for the life of the truck. Not only do they warp under heavy usage (Think towing a lot) but the front wheel bearings are a part of the Rotor assembly and are non-serviceable. Need your bearings repacked? Sure, buy new rotors. Blah!

Kind of. I agree with the European thing but, the American cars still have a minimum thickness to them. See it all the time while I am at the base auto hobby shop watching my buddy resurface rotors. I have heard from multiple sources that you can't really safely resurface the MINIs rotors because they are already pretty thin to begin with and that one set of pads pretty much take care of a rotor.
My wife drives the 12 MCS but I drive an 08 STI and I get the slotted and drilled brake rotors and Ceramic Pads because they usually last longer. Try Getting ceramic if they have it for the mini.

Ceramic pads? I have some alrady(EBC redstuff) or rotors because I already have slotted rotors too(powerslot).
