Just wondering if anyone found a solution to this? I have ATE calipers and they have 2 different sized pistons in (and dust covers) The small piston is 36mm at its widest part and the dust seal has code 13.8102-3603.2 The larger piston is 40mm at its widest part and the dust seal has code 13.8102-4005.2 Looks like the code is partially based on the size - see underline I've actually been in contact with ATE as they have a "classic" section so Ill let you know what they say. BTW Boring fact ATE is actually named after the founder Alfred Teves
My Porsche 993 caliper a look very similar to my 348 caliper a, will have to photo and take a bit more notice, pretty sure they are both ATE (Teves ABS system on the 348?)
IIRC the Porsche ones dont fit - bought the below kit from Brakes International (in the UK) but they didnt fit :-( PORSCHE 944 S2 (1989->1991) BREMBO 4 POT FRONT CALIPER REPAIR KIT BCK4021B Just for the record I even contacted ATE classic departent and contacted them directly and they cant supply the seals any more. Very annoying!
I guess the trick here is to determine what other vehicles share this part.It will be available for Porsche,BMW,jaguar etc but not Ferrari.....odd
