Help! Brakes squeak exactly the same after being replaced.

I would say the same. Are you sure they are GMC pads?? Sounds like too much metal in the pads. They will chew the rotor to death.

I haven’t been under a GMT900 in a while, but in my GMT800 I chased down a creak/squeak at low speeds for the longest time (only really noticed when I was in the drive thru at the pharmacy and could hear the noise bounce off the wall, now that’s all I hear).
Ultimately found that the parking brake cable is rubbing in one of those metal loops / hangers that routes it under the rear axle when I pushed on the brake pedal. I put some lithium grease on the parking brake cable and loop and it quieted down. It lasted all of a week so I need a more permanent solution.

If yours makes noise when you push harder on pedal, while stopped, it may be worth just taking a quick look at the parking brake cables.


Either way, I feel your pain. Hopefully you can get it sorted out soon.

I will have to check. I know they are aftermarket, not genuine but good quality.

The problem is long lasting doesn't mean good quality. IMO. pads with a lot of metal will supposedly last longer unless you do some heavy braking and they start chewing the rotors. Then they will start vibrating/ shuttering when u touch the brakes. It's ok to use aftermarket rotors but not pads unless ceramic. But they are $$$$.

Check your rotor/disc dust shields... Sometimes they get a little wonky
when doing brakes and will just barely rub on the rotor on the inside...
Usually it will self clearance after some miles.. but it is a horrible noise
I've had to go back and straighten them out more than once after doing a
brake job

Do everyone who works on that a favor and skip the anti-seize. There are better lubricants than that for contact points.

You mean things like brake caliper grease?
