What to do with brakes?

So as of a few days ago my brakes started squeeking heavily when I slow the car. It's pretty annoying, I was just wondering what exactly needed replacing, if anything.

Rotors and pads? Just pads?

The odd thing is that my "BRAKE" warning light isn't on. Maybe the problem is something else?

Your pads probably need replacing (please verify). As far as brakes, replace pads, rotor, and sensor...go to www.getbmwparts.com for the brake kit. Bring to your indy, or DIY. As far as the brake warning, I think that is a pressure-related warning system (think air in system, brake line rupture, or master cylinder/ABS issues), so you would not see that warning due to worn pads.

I see. Also, do I need to replace rotors? I know BMW recommends it, but BMW would also recommend us to give them our life savings if they could.

I would replace rotors. The reason being is when rotor thickness is checked, it is usually checked when replacing pads...who knows what that rotor thickness will be once the new pads wear out. If you end up saving the rotors, I would recommend checking rotor thickness every 5000 miles or so.

Oh please. F to a Indy and have them check your brakes. Brakes are easy. Any average guy can do a brake job.

I see sounds good, also, what do you think of turner ms' brake revamp kit, 485 bucks for rotors pads sensors and brake fluid? For an extra 100 you can get turners slotted rotors with some autocrossable stop tech pads.

I feel I could definitely use the heat dissipation and extra bite, I don't autocross but I do some "spirited" driving on the highway often. Usually with any given g37 .

Question 1: is it reasonable to buy the turner kit? 500 bucks and DIY saves some pretty serious costs, by any standards even if I don't go to the dealer.

2: should I opt for slotted with better pads?

61.5k miles. But since I've had the car at 54k miles, I womp on my brakes. God knows how they were used by the previous owner.

Getting a bit ahead o'yourself....you should: Inspect your brakes noting pad & rotor thickness.

How's she measure?

You can just replace your pads if you want after eyeballing for rotor thickness. You don't want a raised lip on the outer side edge of the rotor (or a level, "break even" edge). YOu want some raised thickness as compared to the rim. The pads are typically very soft so you don't get as much rotor wear on these as evidenced by all of the brake dust. Worst case scenario is you put on new pads, its starts squeeking or grinding and you have to put new rotors and pads on again. The only thing that gets hurt is the old rotor, brake pads, and your wallet (from my personal experience).

Due to my lack of self control I ended up buying turners brake kit. Got slotted rotors and stop tech pads.

Those must be awesome. I have the original originals on my E92 with 36K miles. And once around the Nurburgring, several hundred Autobahn miles, and many times around NHIS and Lime Rock Park, with not a single issue with the brakes that came from the factory.
So I gotta figure that with the Turner kit my car would stop even faster and straighter for a lot longer. Right?

Wait wait, all that driving and you must have been hard on your brakes, maybe I didn't need all that, hmm. BUT, from where I looked, aftermarket basic replacements would have been 100 dollars cheaper, and of course OE would have been more expensive. So hey, 100 bucks for some capability I may or may not use? I'd say its worth it, at least I can brag about it to my friends

Also, I'll let you know how they feel once installed, incase you ever need to replace your stopping gear.
