Alright, bought a used blazer a while back. Needed a bunch of stuff, rear pads and rotors were beyond shot, horrible.
Took it to NTB, they replaced both back pads and rotors. They inspected the front pads and rotors and said those were fine.
1,000 miles later, I'm hearing brake sqealing. Consistently at low speeds and it's an intermittent squeak as the wheels go round. Squeak(pause)squeak(pause), squeak(pause). Before I take it back to the shop, what does this sounds like? Rotor defect? Caliper defect? Dirty pads? I can' tell if it's the front or back. Any suggestions or hints would be helpfull, thanks!

Could be a rock wedged between the rotor and pad... could be the pads glazed over... could be a lot of things. Your best bet is to take them apart and inspect them for yourself. It's a very easy job that requires a jack, tire iron, and two basic wrenches.

I'm thinkin' that it's the thin sheetmetal shim clips that go over the caliper bracket and holds the pads. I had to 'adjust' mine to keep them from scraping on the outside diameter of the rotor. No rotor is 100% round, but they are balanced to remove any vibration that would be present if left unbalanced and out of round. Let me see if I can find the pictures I took of the rear brake job.

Also if they did not lube everything properly (they are being paid per job so get em in and out FAST) it will cause a squeak also. The caliper slides, where the pads contact the caliper bracket, and where the pads sit against the caliper should all be lubed with a high temp silicone lube. I used to work with a guy who never lubed brakes, and when they came back (and they did come back) I would just lube everything and make sure where the pads sit in the caliper bracket they moved freely, and that should cure the problem. Also if they used cheap pads that can cause it also. Talking to the NAPA brake rep. he stated that 95% of returned brake parts for noise was due to lack of lube on the installers part. And yes a foreign object contacting the rotor could also be the problem. Korey.
