Just replaced rear brake pads on 2006 QP, using EBC yellow stuff. Got horrible brake squeal, although only done <100 miles.
Done loads of similar jobs on all cars in 3200. I did NOT re-fit the shims as the EBC pads had some already fitted, clamped to pad backing plates. Looked like the OEM (anti-squeal) shims might not fit well as the have a folded tab that interferes with new pads.

Anyone got got experiance here ?

Yes Rob, had exactly that when Shiltech fitted them to the rears on mine. Fixed by using redstuff.

Bah!
Will try re-fitting the shims this weekend. If not will shell out for more pads.
Bit concerned now as I have new front disks on the way and EBC yellowstuff pads

I have a 2006 QP and I tried EBC yellowstuff front and rear pads on new Maserati discs but I simply could not eliminate the squeal. In the end I opted for Formula Dynamics low noise pads and these have worked well for me.

Sorry to bring this thread back from the dead but I was interested in how this turned out in the end? Just put 4 discs and new pads on my '06 QPV and the squeal is horrendous! Any advice please?

Was thinking the same Eb fitted plenty when at Maserati and never any noise with Brembo pads and discs.
Never had issues with other oe spec ones either.
Down here if discs within tolerance we always skim them to take new pads and they work great every time.

It's not a QP, but I have the carbon/kevlar FD pads on Eurospares patterns on the GT. It's only been 10 days but they are very very good so far

My QP is on yellows and yes the rears squeal like a pig, going to try some reds on the rear to see if this cures it.

QP V brake - shims &amp; squeak

Mechanic is suggesting we take the new discs back off the car and give them a light skim to deglaze them.

Sorry but I think this will not work, suggest going to a different pad material, the pad material really needs to be matched to the grade of steel in the disc, and as we don't know this it's a bit hit and miss

Andy, is that a typo? Do you mean "will "not" work?

The rear discs are the worst and they are genuine Maserati so someone knows their metalurgy. Do Maserati make their own brake pads?

Looking back at this is bizarre - when I first had Yellow pads fitted the noise was incredible. Deafening. Susie following me 100m back could hear the noise and thought the car was broken! They were changed, and all was well until I destroyed the pads on track. I then fitted new YellowStuff pads (last year), and there's no noise at all.... All very odd.

I've been speaking to the Aust distributor for EBC pads. He says it's all in the fitment. Pad material is not the issue, neither is glazed discs or pads, (which he says was only relevant when pads contained asbestos). That would perhaps explain your experience Drew? Were both sets of yellows fitted by the same person?

He says the squeal is solely a result of pad movement when in contact with the rotor. If you stop the movement, you stop the noise. That's where the shims, copper grease and brake pad adhesive come in.

If the backing plate for each type of pad is just a little different from another brand then it moves around in the caliper unless you stop it. Variation in pad size and incorrect fitment could explain why we change brands and then swear by that brand when the noise goes away.

Food for thought?
