I was also having a bad squeal on the front driver side. I checked the pads and they were fine but I did find THIS!!! (See attachment) One of the caliper pins was half way out. That's one of the things I don't like about these type of brakes. There are no safety clips or pins holding the caliper pins in.
We've also found that resurfacing the factory rotors doesn't always work. We believe it has something to do with the metal composition of the factory rotors. This is also the case with Ferrari rotors and most (if not all) of the factory dealers will not resurface the rotors because they can't guarantee a quiet car, unless the rotors are replaced.
Also, you need to measure the rotors before resurfacing them to see if there really is life in the rotors. A few owners have asked us for advice to get rid of the squeal and when we had them measure the rotors... they were at or under the minimum spec. You would think that the brake shop would check this, but it seems that they don't always.
If you do resurface the rotors, it seems that turning them on the brake lathe at the slowest possible speed is your best chance for success.
During assembly of the rotor / caliper / pads be sure to clean and properly install all of the hardware and use a good anti-squeal compound on the brake pad backing. Our Pads also have an additional bit of material that helps absorb vibration and reduce noise.
You also want to be sure not to get anything on the brake rotors themselves (i.e. grease, cleaners, etc) unless it is a good quality brake clean product.
Finally, you need to properly brake in pads / rotors. We provide instructions with our pads that detail what seems to work best for our compounds.
We do offer nice rotors for the Maserati that will save you compared to the factory parts. When combined with our Quiet, Low Dust Brake Pads that typically solves the squeal issue.

My GT has several mm of life left on the pads, but the brakes squeak and I hate it. Kind of takes the panache out of owning an exotic car when you come to a stop sign with a bunch of people standing around. I wonder if they are snickering at me and my flashy car. The dealer did some panic stops which solved the problem briefly, then the squeal came back. Has anybody had luck forcing the dealer to truly fix this problem under warranty? Seems absurd to drive a $$$ car that sound like a piece of shit jalopy.
I would say take a look at our Quiet, Low Dust, Extended Wear Brake Pads. They are a ceramic compound pad that offers a great reduction in brake squeal. Check them out:
Street Quiet / Low Dust / Extended Wear Street Brake Pads
We've got many forum members that have purchased these and love them. We designed them specifically because of the squeal problem people were having. Give us a call at (702) 430-1040 to order or if you have questions. They are an outstanding pad and priced just right.
