My 2000 Sierra has the brake squeal too! But its only when you first start stopping. After a few stops it doesnt do it anymore.
It does it horribly in the morning in reverse. :thumbs:

My 2000 does that exact same thing......only in the morning on the first stop..................its definately the pads on the rear......and I just changed them no too long ago.........I also used the same pads I have always used.......this is the only set that has been noisy.

:cheers:

The brakes on my 06 have been squealing for a while at 25k miles. Just turned the rotors and it seems to have solved the problem.

My GMT900 CC had the front pads de-glazed and the rear shoes cleaned and readjusted at about 5k on the clock. My shop also used a BG chemical on the pads itself that was supposed to reduce the squeak, and some antisqueal on the back of the pads. The front sqeal went away for a couple of months, but came back as soon as the weather got humid. Couple of quick hard applications seems to make it go away for a while, but I have to do this almost every time I drive the truck cold. Now that its cold and icy out, I cant stab the brakes hard, the abs just kicks in...
It will be going back in soon to have them looked at again, and unfortunately, there is a couple TSBs that address this concern as well as the dust on the wheels. GM says its normal, unless found to be abnormal, and then instructs cleaning or replacement as neccessary to bring to normal standards. :rolleyes:

My '06 crew cab brakes do not squeal at all. Must be "new and improved" pads for the '07 and later models? But, I must have cheap rotors, because one of them is somewhat grooved at 6500 miles. :rolleyes: For comparison, my '99 Mazda 626 V6 still has the original brake rotors at 181k miles and they are not grooved or scored and they have not been turned to date.

For squealing brakes on any vehicle, the first thing I do is coat the backs of pads (can also do backs of brake shoes) with an anti-squeal paste. That always takes care of it. Auto Zone sells the CRC brand anti squeal paste in a bottle for about $ 6.50. It is orange in color. They also sell little packets of brake grease that they claim can also be used as anti-squeal coating, but I would not trust grease. The paste is a lot better.

I had that on my nbs GMC since about 700 miles. In short, the tech pulled the drums and greased the shoes, where they make contact on the backing plates. Have about 6K now, and no issues at all.

Looks like this brake squealing problem is new for the NBS '07 + trucks. I have not noticed any brake squeal on my '06 crew cab.

I would try anti-squeal paste first. Auto Zone zone sells CRC anti-squeal paste in a bottle for about $ 6. It is orange in color. You smear it on the back of pads/brake shoes and let dry, then install. It stays somewhat tacky. Do not use the brake grease that they sell in small packets - they claim that it can be used as anti-squeal paste too, but I would try it.

If the anti-squeal paste fails, I would explore different brand pads/shoes. If you take it to the dealer, they will give you the same pads/brake shoes and turn your rotors, so in addition to not fixing the squealing problem, you'll have a rotor warpage issue too.
