Sending calipers out to be refinished and the piston boots were fairly brittle. Not all of them, but I figure I'd just replace them all while the calipers are out. Does anyone know what sizes these happen to be? Dealer is guessing, as is Pelican Parts even after I provided my VIN. Last guess was 38mm fronts and either a 28 or a 30mm in the rear, depending on where/when Brembo manufactured them.

Puzzling that dealer would have to guess. I've always gone by the Porsche Parts Catalog for such items as brake piston sizes. I think this is the link to download by model. I found it curious that the rear brakes are from 944 Turbo.

Good luck.

Thanks, Dave. If you look up a lot of the sub parts on these Brembo sourced brakes, you'll see many interchangeable models with variations in piston and brake pad sizes dating back a bit, so I was surprised, as well.
