I put new pads and rotors all the way around a couple months ago, why would my front rotors be warped already, also my break fluid goes down slowly.

Because you're driving it like a bat outta hell? Very hard to diagnose with the limited information you gave us.

The fluid is leaking out though, that's for certain. Just check all your lines for leaks, ect.

Alright dude, i'm not driving it so hard that it would warp brand new rotors in less than 1000 miles. I mean really i kinda suspected a bad caliper, but i was looking for some other kind of educated input. Not just some smart a** remark. Deuche.

Hey twit knuckle, did you bed in your new pads?

Did you check your calipers for leaks? How about your brake master cylinder?

What kind of pads? What kind of rotors? You've also got the craptastic 1990 26mm NA rotors, so they're easier to warp.

p.s. You won't get very far here calling moderators douches...

First, you gave us little to no information. So based off the information you gave us, I suggested a possible cause.

I also told you that the fluid is leaking from somewhere. Fluid doesn't just dissapear, therefore it has to be leaking somewhere, so there's your educated response.

Lastly, calling me a douche (and spelling it incorrectly) isn't going to get you far, as Tony has already pointed out. I've got my eye on you now. You're lucky, because on just about any other forum, the moderators would have banned you right off the bat for that comment. I'm giving you a second chance. I suggest you don't smart off again.

Also, the '90 N/A used the smaller rotors and were 280mm X 26mm, as opposed to the '90 TT and every other Z32, which came standard with 280mm X 30mm. Warping was very common on these. That could also be your problem. ANY kind of "sprirted" driving, and they can warp. The brakes just aren't big enough to support such a large car.

EDIT:

Just noticed Tony had already posted this info.

That was pretty uncalled for.
