Squeaking brakes 2019 AT4

[Chris walker]

I have a 2019 AT4 that has horrible brake squeak at 20k miles. The squeak only happens when the truck is cold for the first 3-4 stops. Its loud enough to wake the dead, however. The brakes show 30% wear so they shouldn't require replacement. 

 

Has anyone experience this and are any of you aware of a solution before I take it to the shop or start pulling wheels off?

 

Thanks for your help in advance.

I have the same problem and it's only first thing in the morning usually. Then after a brake tap or two it's gone. Never experienced this in any other vehicle I've ever owned unless brakes were toast.

Has it ever had a brake service?

Check pads, lube slider pins...

My 20 does this mostly when it's cold or sometimes after it rains. After the first 2-3 brake applications it's gone. It's an issue I have seen people on here complaining of before.

I have this too, but it's only a light squeak.  2020 Trail Boss LT.  After 2 slow speed stops it goes away.  I have 2 stop signs in my neighborhood with a 15 mph speed limit before reaching a road with a 35 mph speed limit and a braking requirement of more effort.  It just sounds like cold/dirty brakes.  My truck also has 20k miles.  Reality is, brake pads and rotors are metal.  They're going to squeak a little.  It's natural.  Manufacturers put a lot of R&D into not letting the squeak, such as chamfering, or putting a channel in the middle of the pad, but as pads wear the benefit of the tech diminishes.  Have you ever heard the squeak brakes make in a semi, a city bus, or a dump truck?  It really is normal.

My 2022 has the same screech but all the time. 28,000 Miles. 94% breaks and GMC says it's a wear item and won't fix it. But for $480 front and $480 back they will put new pads on. 

For what they cost this should not be an issue.

Take it out and brake it hard a couple of times. Knock the glaze off.
