I have 2016 Chevrolet trao suv. I bought it a couple years ago. It has about 15k miles. All right so other than the problem I’m having it’s been a okay car. But here’s the problem..

It makes a loud noise at the end of a stop when I brake. It’s not a grinding noise. I want to say it’s closer to a squealing noise?? It doesn’t do it until the car comes close to stopping. It’s loud enough where everyone outside always look at my direction and whenever anyone rides with me they tell me I need to change my brakes.

All right so you’d think a mechanic would look at it and fix it. Wrong. I’ve been to like 5 mechanics and they all say my brakes are fine.

It’s driving me fucking nuts. I’ve owned several cars and none of them has ever made this noise. Anyone ever have this problem? Where your relatively new car makes a loud noise when coming to a stop and it wasn’t your brakes? What else could it be?
 
I'm having my road test tomorrow so hit me up after 11:30am EST fam, I got u
 
I think that's the sound of your warranty expiring.

On a serious note; take a video and post it. Do you have any kind of idea where it's coming from? Does the car move in a particular way with the sound?

Is it consistent every time with the brake pedal? Are you able to test it on a slope and see if you can get the car to come to a stop without using the brakes? That might help eliminate the whole brake system.

I would guess it's your wear indicators on your brakes, but apparently not? Maybe your bearings? I don't know a lot about cars but that would be an uneducated guess.
 
Put the car (SECURELY) on jack stands or a lift, have someone sitting in the car put it in drive, get the wheels turning then slowly apply the brakes. Listen closely for where the sound is coming from.

If you don't hear the sound with the car off the ground, it's likely a suspension part.

Is the sound coming from the front or rear of the car? Left, right side or both? First step to diagnosis is determining where the sound is actually coming from. That's what a competent mechanic should've done for you.

Were any of the mechanics you took it to able to reproduce the sound? Or did they just take a quick look at the brakes and tell you they're fine because they didn't notice anything obvious? Sometimes tiny little rocks or other debris can get stuck in the caliper but it could be something even less obvious. If it is something like a rock, you'd have to at least take the pads out and clean everything up. With the caliper and pads out of the way pull the rotors off and inspect them closely on both sides.

If the mechanics you took it to didn't completely disassemble the brakes and just pulled the wheels off and did a visual inspection they easily could've missed the problem.

I had that exact same noise once and it ended up being a dead hooker rolling around in the trunk.
 
Is your name Fred?

Are your feet sore?

I hate it when that happens! Hard to remember to ditch those hookers.
 
Your brakes can squeal even though there isn't anything wrong with them. The brake pads are hard and can glaze which can cause them to squeal. The rotors can have some rust but still work fine. The mechanics are trying to save you money. Many would have told you to change pads and rotors. You could take the pads out and sand the surface and sand the rotor surface.
 
If your pads are low it could be your wear indicators trying to tell you something. If not you should pull the pads out and put some anti-squeal or anti seize on the backs (I know everyone likes something different). Or you may just have really shitty brake pads, if so swap them out for some nice ceramic pads.
 
former Tech here. I am assuming your brakes are original. Always check the easy stuff first, is the brake fluid low? Does the steering wheel shake when you stop?
 
Must still be under warranty with 15k miles ?? If yes, bring the fkn thing in to dealer

The bolded part is what I would be looking at. I can't tell you how many vehicles I've seen with pads where the material wears to an ultra-fine point on the edge of the pad. When this occurs, you usually have a high pitched squealing that is very similar to the squealing you get from a wear indicator touching the rotor. More often than not you'll hear this squealing when lightly touching the brakes backing out of a driveway in the morning, or at random when coming to a stop lightly on the brakes. I have sanded pads down for people and the noise usually goes away for a few months, but will eventually come back. I would suspect the mechanics you took the car to are simply looking at the pad thickness and not actually removing the pads to inspect them. If they did, and the problem is what I mentioned, it would be immediately apparent to them. I find a lot of ceramic pads tend to wear like that on specific cars. I have witnessed OEM brake pads that came with the car do this as well as aftermarket pads from various brands.

Agreed. I have a friend with an Audi S5 with a similar problem and ceramic pads fixed it. Different vehicle types, I know, but swapping the pads out could very well fix the issue TS is having.
 
It's your brake pads. As other posters have noted, they need not be worn out to become noisy. Check the pads for debris and perhaps replace them. Rotors don't need to be resurfaced unless they're warped or grooved.
