07 coupe.....warped rotors?
Ok i know alot of people have a problem with the stock brakes getting warped very easily. i have an 07 coupe 6mt with about 20,000 miles and the brakes are already warped...what gives. previously i had a 03 maxima with the same problem i was constantly having the rotors cut. but i had an 06 acura tl six speed sedan and the brakes were awesome. (i think they put brembos on the six speeds). anyways i have the problem again and cutting the rotors isnt going to make it go away for very long because i drive through mountains on my trip from new jersey to my college at west virginia university. Im wondering what would be my best option to fix this besides spending thousands on a new set of brakes and rotors. if anyone can give me suggestions of the most cost effective fix for this problem, because i am a poor college student
. possibly a set of inexpensive larger brakes? also the acura i used to drive is actually my parent's and the lease is up soon. i think my dad would be willing to let me swap the brakes with the acura and i looked up the specs. they are 310mm brembo rotors. and the calipers i believe are manufactured by acura. is there any way to put these on my car. or what options do i have otherwise.
i appologize for the long post but i hoped that my description will be useful
thanks guys.

also i know the fronts are pretty warped, im not sure about the back but recently when i take the E-break off and pull out of a parking spot i hear a click from the rear which i never noticed before, i think it may indicate that the rear rotors are warped as well. not sure tho.
one more question, since my car is under warranty, do you guys think if i took it to the service dept. they will help me out? they have always been good in the past (even replaced engine for OC)

You're probably experiencing some other problem, brake warping is pretty rare. Here's a great article on the topic, with alternate explanations and how to address them. Most likely, you got your brakes super hot on your hill descent and some pad material deposits itself on the rotor in an uneven pattern. Read the entire article, but the short of it is that you may be able to get your rotors resurfaced and then bed the brakes properly to avoid the problem in the future.
Ususally the caliper to spindle mounting points different slightly from vehicle to vehicle. SOmetimes you get lucky, but most of the times not. Also i beleive the calipers are Brembos, but with the ACura logo. Not sure though.
Also, brake "warpage" is usually pas friction material from the pad to the rotor unevenly. It usually happens when the car is stopped hard and then you sit on the brakes at a red light. The hot brakes cool and some material from the pad transfers to the rotor. Do it enough, and this is the pulsation you percieve as "warped" rotors.
The fix? Different pads, but sometimes a driving style change can help too. Allow your brakes to cool. If you brake hard to a stop, rest your foot lightly on the brakes or let the car creep forward slowly. Also, if your brakes are hot, don't set the parking brake until they cool.

among other things i looked at the rotors and it seems some parts are a slightly different tint then other parts in a smooth pattern around the circle. could that be the break deposits?
but on the topic of resurfacing, is this going to be a recurring problem once they are resurfaced? is there a cheap alternative for stock rotors? maybe like a $500 replacment set of rotors and pads that wont have this problem?

You might want to look into a set of 03-04 Brembo G35/350Z brakes. They are a little more massive and might help with the heat better.
If you want to invest more money beyond that, a BBK might be the best option.

The obvious question now is "is there a "cure" for discs with uneven friction material deposits?" The answer is a conditional yes. If the vibration has just started, the chances are that the temperature has never reached the point where cementite begins to form. In this case, simply fitting a set of good "semi-metallic" pads and using them hard (after bedding) may well remove the deposits and restore the system to normal operation but with upgraded pads. If only a small amount of material has been transferred i.e. if the vibration is just starting, vigorous scrubbing with garnet paper may remove the deposit. As many deposits are not visible, scrub the entire friction surfaces thoroughly. Do not use regular sand paper or emery cloth as the aluminum oxide abrasive material will permeate the cast iron surface and make the condition worse. Do not bead blast or sand blast the discs for the same reason.
