Brembo GT Brakes are LOUD! Any other Brembo GT users have experience?

[EndlessAzure]

From a fellow owner, all I have to say is welcome to the Brembo GT life. Normal by most accounts. Even OEM PP Brembo owners have commented about increased noise.

I've had mine for about a 20 months (> 20k miles and > 10 track days) and am usually driving on the provided OE-spec pads on the street. I swap out to dedicated track pads for road courses.

I distinctly remember them being squeaky when I first got them (some lady even asked if something was wrong with my brakes), but having dailied track pads for 2 years prior to that it didn't bother me. They've gotten a little quieter as they've aged, but they still make noise from time to time. Noise was excessive on my track set over the first couple of uses, but they have also since quieted down.

Speaking from experience: no amount of bedding changed initial noise. At the time, I did a couple of full bed-ins to temperature on the OE-spec pads (10x 60-30MPH, cool, then 10x 60-10MPH; hot enough you can smell the compound, sometimes see smoke), but the noise always came back not too long after. These days I don't bother with a comprehensive bed-in on the street set. I don't use any brake grease as it generally burns off at the track anyway. I think noise characteristics will start to improve once you really wear into the rotor material, but obviously that just part of normal brake usage (I'm about 0.7mm into the rotor thickness).

I have a couple of theories on why the GT may be more susceptible (wear-off of the zinc coated rotor, presence of slots), but they are just speculation. I'm interested to see if things are any different with standard blank rotors, but I have my eyes set on 2pc rotors down the road

Off topic for this thread, but what 2-piece rotors are you looking at? I was wondering if the 2-piece Girodisc rotors would fit. They make some in the exact same dimensions as the GT rotors.

It's between Girodisc and Project Mu SCR-Pro for me. It's worth noting that the Project Mu 2pc rotor hat adds 1mm of offset

I've seen on the forums that people have had good success with Girodisc.

Brembo might offer a 2pc option, but it's hard to find info on them. Paragon also has an offering

Not keen on DBA 5000, as they provide relatively low weight reduction benefit compared to other alternatives

CP is in the same category as DS2500 similar to Yokohama A052 is in the same category as Falken RT615K, but with a different performance profile. The Brembo GT kit is more rigid than the OE Brembos so the resonance profile is different for performance and street pads.

I tried some carbon fiber stickers and they eliminated the noise, but on the first trackday they melted and smelled burned��

Now I'm going to try DBA discs, I expect a lot of noise.



By the way, did you remove the back shield from the disc?

Do you mean the dust covers? I installed the OEM PP dust covers in place of the stock ones.

they are as the pads work perfectly parallel to the rotors. it is a feature, not a bug.

I do own this kit and my experience was exactly the same as yours. Loud AF on Brembo supplied dual purpose pads. I've switched them to DS2500 and it's much less noisy right now even without any kind of friction/noise reducing pads installed. Brembo b-quiet didn't help at all too. This topic has been over the forums and Reddit many times. Here's my reply to one of the Redditors some time ago

Thank you for saving me the effort of removing the pads and greasing them. I was actually looking at giving the Brembo B-Quiet a shot.


It sounds like I will be getting some new pads in the near future.
