GTA 330mm squealing brakes

Do you have the 330mm v6 brakes as fitted to 147/156 GTA, or maybe 3.2 Gtv, 3.2 Gt or have you upgraded to these brakes? Do your brakes squeal? Simple question really, I am trying to gauge how common it is for these brakes to squeak, I suspect most do squeal but please submit your honest answer. Cheers!

GT 3.2, Brembo OEM discs and pads. Minimum squeeling, not really loud, only just before coming to a halt

OEM Brembo.

They do squeal but only when the pedal is pressed VERY lightly!

This poll is confirming my suspicions... There is something inherent in these brakes beyond the discs and pads, that makes them squeal. Thanks!

I remember years back talking to Ned at AutoLusso about this. His theory is that the GTAs brakes have to be used hard reasonably often - if they are, they won't squeal (might be misquoting, but I think the theory was they were 'glazing'). Unfortunately, in normal driving, I am very easy on my brakes.

What's true for the brakes on a GTA is not necessarily what's true for other brakes. Everything in this thread suggests that they're more prone to it than other cars for a start.

Certainly, a few high speed heavy braking sessions seem to reduce the squealing for a little while.

Crappy old pads, worn lipped discs = no squeal
Mtec c-hooks, PF pads = squeal (at low speed coming to standstill)

Used lots of copper grease on backs of pads and edges where they slide. Greased pins. 1 week after fitting squealing started. I guess there's no answer!

I can honestly say in my 3 years of owning my GTA, I have never had brake squeal. It had standard 330 set up when I bought it and for the last 2 years Iíve been using EBC Turbo groove drilled discs with Yellow stuff pads and still no squeal
