Okay so i bought my 2007 LT brand new.........still has a warranty

i have just under 19000 miles and the front rotors are warped incredibly........it feels like the steering column is gonna rattle off the firewall when i brake so i know its the rotors that are the culprit

is there any documented defects on the rotors of the cobalts? In other words im basically asking if this is covered under warranty

 

Yes, There even might be a TSB about them. They will probably resurface them and reinstall.

 

ya i figured thats what would happen.........brakes dont go bad at 19K miles lmao

 

They do on a Cobalt

 

very very true im pretty sure im not the only one with this problem..........is it worth just going cross drilled and slotted......i understand they are better but is it worth the extra $$$

 

where can you get the drilled and slotted

 

ebay or almost any supporting vendor on here

but are they worth the money?

 

mine warped at 12k and again 8k later first time they covered under warranty. haven't checked about the 2nd time though

 

Slotted sure, drilled not really

"Some" say drilled rotors are more prone to cracking and don't offer much performance increases.

 

did they resurface or replace?

 

resurfaced. felt like new for say the next 8k

 

sounds good........how long it take i would like to get it done tm and get it back the same day

bump?

 

it was all done the same day. a few hours. don't remember exactly. it was like 1.5 years ago

 

lol ya i figured such........i need to get this done tm.......im booked up for the next month

 

15k is WAY past where most dealers will warranty. Most consider 5k to be within the "warranty" range. 15k is sooner than normal but not so soon that improper driving, over torqued wheels, or other maintenance error could be to blame. Good luck though.

"Some" would be correct, except that I'd go so far as to say they offer NO performance increase, and in some cases DECREASE performance and longevity of the friction material.

I don't even recommend slotted. They're not as bad as drilled, but they don't offer enough improvement over stock to be worthwhile.

The key to good braking is proper fluid maintenance and properly matched pads and rotors (and decent driving skills). I've been on OEM rotors and Hawk pads for 40,000 miles with no grooves, marks, warping, or anything what so ever. Granted, I'm going to need to replace them in about 5k, but 45,000 miles out of a set of brakes that have 4 road racing sessions and a handful of auto-x's on them ain't bad at all.

 

now im pissed............the dealer said they arent even gonna cover it..........they claimed that the rear drums are out of adjustment.........and that is the cause of warping the front rotors.......they havent even looked at my car yet aint that some ****

anyone else get told to **** off by the stealership on this issue? bump?

 

they prob cant turn them if there that bad.

there soooo thin. and new ones arnt thhhhttt bad.

i would just do what i have and buy new rotors and pads from your local parts store and do it yourself.


slotted/drilled, are garbage on low HP FWD cars. there just going to crack. get blanks and ceramic pads.
