Default Grinding noise slow hard braking?

Sometimes when I hit the brakes hard when I'm not going very fast I get a grinding noise from the front end. I don't think it's ABS, no traction control indicator. Suspension is stock. Example: pulling into a parking spot, and hitting it more than normal, but not flooring the brake. Most times the wheels are straight ahead or slightly to the side. Is this normal, something I need to get fixed? Anyone else have the same thing?

Mine does the exact same thing, seems to be when turning into parking spots and coming to a stop. Like you said if you make sure to do it slow it won't happen, just seems to be when braking harder than usual. I figured it was probably normal, but who knows?

Mine makes a "scrunching" sound, almost like a bad shock.

Sometimes left front, sometimes right font, mostly not at all.
Under light braking no noise, car doesnt pull either. Rotors are smooth.

I'm thinking it's just situation where a little extra dust, rust or road salt get on the pads and make some noise for a bit.

I know you said it wasn't the ABS, but it sure sounds like that to me. I think it's the ABS pump that makes that noise when it detects some tire slip.

Sounds similar to the JerryC scrunching sound. I'm going so slowly when it happens it's hard to believe the ABS is activating. ~5mph, mostly happens when parking.

Its not quite the same noise as ABS, and I doubt very seriously there is any tire slip on a dry parking lot when coming to a stop. Its not like you have to slam on the brakes for it to happen.

The only other thing I can think of (and this might be hard to explain) is that noise your brakes make if you are sitting still on a hill and lighten up on the brakes. Anyone know what I'm talking about? If you let up on the brakes a little, right as the car starts moving it makes that grinding noise as the brakes gain and lose traction. I think all cars do this. Maybe the pads on the new Mustangs just do it worse than normal. If the noise sounds similar to what I'm talking about, maybe you could try some different pads. Maybe the pads just vibrate or something right as you're stopping.

Thats what it sounds like, just weird that it does it so often.

That's it. I thought the same thing the other day when i let up on the brakes a tiny bit and it made the scrunching noise, it was a lot quieter, but that was the same noise.

The noise stopped after a couple of days. It i snowing again, i wonder if the nosie will come back with the road salt.

It's not the same as the low pressure grinding when letting off the brakes. It happens when I'm applying the brakes with greater force. I also noticed today thanks to an emergency stop that it happens when I have the wheel turned.

Mine got bad enough that I took it yesterday and the dealer replaced the front pads and surfaced the rotors. Noise is gone, for now.

Default Front Brake (?) Noise

2011 GT/CS.... experienced grinding noise which appears to come from front passanger brake...which you can feel on the floor (suspension ?). Noticed this before first oil change (8000K) and service department checked it out and found nothing. Stored car for winter, and on second oil change (16K) complained again and took tech for test drive who also noticed noise. Resurfaced rotor yesterday...after complaining dealer ate the cost (maintenance not mechanical)...today...noise is still there but lessened! Any ideas?

You post was very helpful to me. I live in a town that has a ton of salt and dust now that winter is gone and I heard that exact noise for first time 2 days ago. I work at a garage and got mechanic to check it out...front brakes are all good...he took off pads and lubed and was ok after that until 2 days later...I went for ride and I was almost home and the noise started again...I showed my husband your post and we went outside and hosed down wheels and brakes...I took for ride and everything fine...So I thinks your right, just was dust and salt that settles in brakes. Thank you and all ford mustangs forums
