Hi all, I need some help please as I'm a bit stumped!
So I have Brembo 4 pots up front on my 595, and, I recently changed the pads from the OEM Brembo HP1000's to HP2000. Reason being the standard pads are not chamfered, have no internal slot for dust expulsion and are generally not as good as the HP2000 revised offering.
Anywho, after bedding in I found under light braking the HP2000's were squealing really badly. Some firm braking and heat cleared the issue up. As I use the car mainly in traffic, I decided to remove the pads and just try some very plain, non-flashy pads (with no metallic compound) and see if I still had any problems (EBC Ultimax 2 which surpisingly, I'm finding work very well. Nice initial bite and response and slight modulation in the pedal so not rock hard all the time, and they have a good coefficient of friction).
Everything appeared fine until recently I noticed I still had the squeal, but, only when braking and turning right at the same time. Just to clarify it isn't a squeak, it is a high pitch pig like squeal. I can be turning and apply the brake and get the noise or braking and then turning... and get the noise. Letting off the brake or straightening the wheel resolves the issue.
Now I cleaned the caliper thoroughly and I used Brembo's own B-Quiet lube on the rear of the pads, the 4 piston faces, the sides of the pads and their contact points where their edges sit in the caliper, and, pins (including in the holes where the pins fit through). All as mentioned by the B-Quiet lube as where to be applied.
Any ideas why it would only now squeal when turning right (and from the one wheel by the sounds of it, the drives side front)? I was thinking is it because I had the wheel turned out right when doing the pads... should I have left it straight? Have I somehow caused it to be flexed? There is no dust shield behind the front discs for any sort of metal to be touching the disc. The disc faces are wearing nicely. You can see after the morning oxidation is worn off the faces are all nice and evenly cleaned.
I don't know what to do apart from maybes put even more B-Quiet on the rear of the pads and pins and try again.
Thanks!
