Anybody have squeaky brakes?
During easy low speed braking my brakes are squeaking badly. 
If I went and did a few aggressive stops 5-10? would that help out? There's no sense in burnishing them as I don't track it.

Burnishing them is not just for the track. According to GM, it will greatly extend the life of the pads/rotors. It also will greatly improve brake pedal feel and stopping distances. I've had a couple customers comment on the brakes being noisy right off the bat, but the burnishing procedure also helped that.

Thanks for the reply.

Racer,
My brakes ('10 model, year and half old, 5,000 miles) have never squeaked, either before or after burnishing.
I don't know how many miles you have on your ZR (or the duty cycles your pads have seen since new), but given the recent evidence posted by jas (jvp) that one might not be wise to place absolute confidence in the pad wear indicators, you might want to pull the pads and have a look-see.
I only know of a handful of other ZRs in my area, although I've spoken to most of the owners, and none of them have reported any squealing, let alone a persistent squeal (interestingly, one did report he had and cured the rotor vibration problem). And I don't recall any CF posts indicating such. If mine started doing it, I'd yank the pads and have a look.
I apologize, obviously this not much help for you.

Agree with Rich. Burnishing is something to do even if you don't track/race. Never heard these brakes squeak though, either before or after burnishing.

Well if that's the case - i.e. pads with little wear - you might want to go ahead and burnish them. I bet that will "smoke" (pun intended) that squeal away in short order.

My brakes currently squeaking like a freight train under those conditions, 3300 miles, 1 track day, street & track burnishing complete.

I have Burnished my pads, have 6,700 km on the car, I don't baby it and I have brake squeal on some slow stops. Looked at the pads, no wear. They work great, no problems, I guess the noise is just something to put up with. I have a 2011.

I would do the street burnishing procedure outlined in your owners manual. Once done, it's done for that set of brake pads. It won't go "bad" if you don't stop hard enough and often afterwards. The procedure brings the pads up to high temperature so the bonding agent (glue) can bake out of it.
