Chevrolet 2016 Colorado Z71 V6 4x4 132000 Automatic
Hi was trying to get to the bottom of why my truck was making this sound when hitting the breaks . Mechanic gave me a list of things he recommended to replace which included upper and lower ball joints. Would this be the cause? I was able to replace the breaks and rotors but still has grinding noise. Left a YouTube video link of the exact sound it makes as a reference. Have not been driving my truck due to the noise progressively getting worse.

Your noise doesn't sound like bad or worn ball joints. Worn or bad joints would sound more like a popping or clunking noise, if you hear something.. Sounds to me like it's coming from your wheels, or more specifically your brakes.
that sounds like brakes or bearings.
Jack it up and rotate the wheels by hand
No sir I assumed the squeaking and grinding were bad breaks but after the mechanic changed them out the sound still persists.
Find another mechanic. Seriously, any respectable mechanic knows you have to identify what's making the noise before you can fix the noise. Throwing parts at it only benefits him, not you.
Just to make sure, you replaced the brakes and rotors yourself?
The noise was the same before, and after changing?

This sounds bad, but I would be double checking to see if he actually replaced them. I had my brake pads changed on my SUV because I was moving up north, and towing a good bit before this. The fronts needed it, but the backs I knew were not as bad, but I told the shop to replace front and backs, I provided the Akebono pads. I knew the place, and I thought I could trust them. After moving up north, I discovered the rear pads were never changed. Now I always ask for the old parts back, and I usually do the work anyway. Trust nobody, or at least trust, but verify.
