Brake noise when slowly stopping 2015 GT PP

[Zirken]

I was just wondering if anyone else is having this happen? I have about 5000 miles on my car but its been doing this since ~4000. It happens every time I slowly go to a stop once the brakes are warm and keeps getting worse. You can also feel it in the pedals when it happens.

It is not a squeal and more of a droning sound like the pad or rotor is vibrating.

I had the car at the dealership for two weeks but they said they couldn't get it to replicate.

Have the exact same thing with my stock PP pads and rotors. What did you find out?

No I haven't found out anything more. I took the pads off and re greased everything which didn't fix the problem. It seems to be doing it less now with 9000 miles but I still plan on just changing the pads and rotors.

Mine does this sometimes too. The brakes in general are very vocal, but they are performance brakes, so it's not entirely unexpected. If you really get on the brakes, they are perfectly quiet.

That is exactly the issue i had along with squealing in the back. Brought it in and they said they cleared it all up by cleaning out the brake dust and deglazing the pads. LIES. I heard both noises by the time i got out of their parking lot (but they closed the door behind me). I know they took it for a 4 mile ride too and to test it gauging by the milage. The left hand accelerometer was also higher than when i left it but wasnt too high. They alao kept asking where i bought the car, sorry it should not matter, im not going 2 hours back out east for a brake fix.

I too have a cell phone recording where it is louder than the blinker and at times it is louder than my music. You can feel it in the pedal and can feel the phone vibrate in the recording. My normal drive is a 9 mile straight highway shoot with no traffic to brake to and it usually starts after i get off th le ramp. Besides its first drive home i havent drove it further than that in one shot. This started happening to me at about 500 miles.

Get it up to about 70 mph and do some heavy braking 70mph down to 10 mph... should help out

My rears have been doing that off and on for about 5k miles, plenty of pad left but they squeal occasionally.

This..
Bed them in correctly. Should reduce or stop the noise.

That works briefly, and then they glaze over again.

Yeah I have done the same thing, will work for a few days then the squeal returns. I guess I'm just going to turn the rotors and replace the pads, I'm sure that will take care of it.

Turning them will likely make it worse but in for the results. Performance pads and street driving will make noise. It does not keep enough heat in the Rotor to keep them bedded in.

That is normal brake noise from 6 Piston Brembo brakes with 15" rotors and high performance track pads.

Brake noise is the price you pay to have a high performance, track ready brake system.

I had a similar noise, more squeal with less drone than your case.
The first track session over the Memorial Day holiday weekend cured it and it has not returned. If it does return at some point, I'll prescribe another track session. Performance parts are generally happiest working within their designed performance envelope. These brakes need to be worked at least occasionally and not pampered 100% of the time.

Noise is far from normal, I will take mine in this week.

"Track? Track? Who said anything about going to the track? Not me? No, no, never! The rubber scuff marks? Must be from the newly laid black-top on my street..."

:cheers:

My brakes squeal under soft braking. The pad sensor shim fell off one side when I changed to track pads recently. so I figured that that was the source.
