I just bought an '08 TC with 125mi on it two weeks ago. Odo now reads 1800mi and the rotors (including outside surface) look like a DJ record and squeal like nails on a chalkboard.

Problems with the rears have been well reported around here on most '08s and some '09s. Unfortunately Chevy won't acknowledge any problem, so warranty coverage has been like pulling teeth.

Knew this was going to be a problem before I bought the car so I already have money set aside for improved brakes and rotors. I just want to make sure that by replacing pads and rotors I will indeed solve the problem, and that the calipers aren't an issue. Some have chimed in and said caliper pins have insufficient lubrication and that the inside pad wears unevenly and prematurely.

 

Well I've got about 4,000 miles on them now and still no signs of grooving or anything like that

 

Just lube up the sliders on the rears if they dry and that's the case.

It's only 2 bolts holding the top portion of the caliper on. 18mm, or was it a 16mm... meh

 

Couldn't be happier with my R1 Concept rear rotors and Hawk HPS pads. Great looking, and judging from others' experience, they should hold up great.

 

You still running stock rotors on the front? Any issues with brake bias?

 

My front rotors are in my trunk right now in need to put them on

 

ive drivin over 6k since and literally smooth as butter

 

What pads are you going to use for the front?

 

Probably stock ones

 

Do you know if anyone has tried the HPS pads on the front?

 

someone needs to mean a rear dust shield to actually help you guys out.. has anyone looked at using the ones from the sky or solstice and modifying them? thats whats killing your guys rear brakes the **** getting in between the rotor and pad

 

No dust shields and no issues with Hawk HPS rear pads after ~18k miles now. It's the factory pads.

 

the factory pads are a soft compound if i remember .. which is further exacerbated by the fact that there is no dust shield

 

cant do it.
there is only one authorization code and download, youd have to buy 2 stage kits

 

I found that out but there's another way of doing it

 

robbing a parts department?

 

I don't know but Vince has a way

 

My inside pads and rotors just got grooved like crazy and started suddenly squealing like it was metal to metal not the normal cold brakes. Must have gotten some junk in there or something but I wasn't about to take the wheels off in the rain for a closer look. Pads were about 1/2 worn inside and outside at 22.5k miles.

Either way dealer replaced the pads and rotors under warranty no questions asked. Took 3 business days to get parts.
