No...I suspect the problem is with hung up pistons... it is just not worth screwing around with: you raced Alfas if installing the correct pads does not cure the problem ...I do not see any other alternative if all else functions properly... For less then a really good set of pads from Performatek - Online Catalog photo from our race tream

Front brake pads too thick

Just a quick note for others to make their own conclusions.

I just received new front brake pads. I cannot get them to fit.

Here are photos so you can see how large they are and determine for yourself if the pistons could be pushed in far enough to allow them to clear the disk.

Alfa doesn't leave any play I. This area. I like to use a C-clamp to compress caliper piston carefully and fully. Make sure dust boot is not interfering with full compression... they will fit!

As I don't like to do most of my own work anymore....(tools, lift, space req`ts) my input would be, "make sure the mechanic or the shop are used to work on old Alfas"...
I`ve been lucky I guess to find an old Alfa mechanic within 10 miles of my home

Well, here's another guy who couldn't get the pistons fully retracted front and rear n my S4 with 97K miles. I've done many pad replacements on my other cars over the years but these totally vexed my best efforts.

I took the cowards way out......nope, I didn't go to the brake shop. I bought new Wilwood calipers for the front and new Alfaholics for the rear. Extreme??, perhaps, but those ugly, heavy, and obviously tired ATE units were begging to be put outta their misery.

So, after going to the Summit Racing web site and seeing the Prog 65 warning, I have one question. Does everything in California give you cancer?

Another point.

Be sure to check alignment of the cut-out section around the lip of the caliper pistons since it is important they be oriented per the service manual.

Apparently engineers who designed the brakes were concerned even piston pressure on the backing plate will cause the leading edge of the friction surface to bite more forcefully into the rotor and by providing the small cut-out section, there will be less pressure on that area and the pads should wear more evenly. After piston dust boots are installed, a special tool is required to turn them to their proper position by inserting the tool inside the piston body. Without boots in place, they may be turned with conventional tools.

I made a cardboard template of the orientation guide and used it to get the job done.

Details are available via search.

Those pads look too thick too me. A year ago, I bought a set of pads that were slightly wider than the Ates they replaced, making contact first on a small, unworn portion of the rotor and seriously compromising brake performance. I am now paying more attention to pad dimensions before I buy them.

I rebuilt my front calipers and purchased new ceramic pads and rotors from Brake Performance. The pads were too thick and I assure you, the pistons were fully retracted on both pistons.
