Anyone with 6 piston brembo fronts

Robert215 · 07-26-2016, 09:41 AM

Dealer says this a normal sound and I have a hard time believing that. Everything is 100% functional but it's driving me insane. Does anyone with the 6 piston set up hear the same noise??

Appreciate it!

I'm at work and cant hear the audio, what sound is it, a squeak/squeal? if so, then yes, unfortunately that has been ruled out as normal...

Robert215 · 07-26-2016, 10:43 AM

Wouldn't say it's a squeak or squeal, more of a rubbing noise, when you get a chance later check it out

I wouldn't consider that normal. I'd pull the wheels and rotate the rotors by hand and see what's rubbing. Sounds like maybe the pads needs to be reset or something is off center somehow.

I have em, and if the pads/rotors are warm meaning I've been using them and at low soft speeds I hear a very very faint squeal. but they are high perf pads so I'm assuming that's normal. its not enough for me to complain about it.. and I'm anal about stuff like that.

I'm hard of hearing. I would follow the advise given to jack it up and spin by hand. What I'm hearing sounds like a warped rotor, so part of the rotor is dragging on the pad and the rest isn't.
I don't know how much bigger the calipers are, but I've seen the type of wheel weights used on these cars rub on brake calipers if there isn't enough clearance. That noise usually doesn't last long, either the wheel weight gets knocked off or the lead wheel weight is worn down pretty quickly.

I've never heard of so many issues on a car being called "normal". It seems like 90% of the time I read about an issue someone is having they say "it's normal".

Robert215 · 07-26-2016, 11:24 AM

Yeah we had them pull the pads and spin the rotor and it didn't make any noise, but it for sure seems like there has to be a high spot on the rotor, but when it was on the jack we spun the other side and it made the same exact noise, it's coming from the top of the caliper, and we had the system re bled and still it was there, and GM doesn't want to warranty it cause it hasn't "failed" it's very confusing situation lol

I don't notice that noise on mine. Some of that noise is normal but if that recording is from inside the car with the window down it seems a bit much though there likely isn't anything "wrong" you just have some noisy brakes.

Yeah that's what I'm starting to lean towards because there fully functional, it's just hard to accept that

Speedy1975 · 07-26-2016, 01:29 PM

Not on a $3K brake upgrade option. I'd want them fixed.

martelds · 07-26-2016, 01:40 PM

That can't be normal.

Robert215 · 07-26-2016, 01:50 PM

That's exactly what I'm thinking alittle noise I'm fine with but for how loud they are they don't seem normal, thinking possibly going to another dealer and seeing if they are willing to do something about it since mine won't

It's a hard pill to swallow for sure but brakes can be noisy. The brakes on my 2500 sounded like metal to metal brakes off a dump truck. Horrible squealing/scraping noise. I took the pads of and wirebrushed them I used a spray thats supposed to quiet the brakes ... in the end replacing the rotors and pads was the only way i got rid of it. Just something about the surface of the rotors mixed with teh pads was creating this noise. Technically nothing was wrong. You may get the dealer to comp you a set of pads/rotors if you push hard enough. Maybe call GM customer support. I can say from experience with gm support involved things get done faster, especially shipping on replacement parts.

Yeah that's a good idea, I sent them a email last week and got nothing, so I will call and tell them what's going on, and another thing to add to that noise is that once a slightly tap the break, the noise goes away, and once I let off its back
