Hello everyone, I am a newbie to this forum. I have a set of Brembo calipers acquired in a parts trade. The rears were easy to identify, however I cannot find a listing anywhere for the fronts. They are not in a catalog, I checked with the local dealer with no luck, but an internet search found mention of the numbers on one site in a foreign language as being up for sale. The part numbers in questions are 996.351.427 and 996.351.428 (possibly 996.351.429), with the eight digit numbers being 20.7310.03 and 20.7310.04 respectively. I could provide brake piston diameter, is that measurement taken from the piston face that contacts the pad, or the piston cylinder itself? Pictured below are the calipers with the color removed for number clarity. The 427 is clear, the 428 however could be 429. Being a pair 427/428 makes sense. The .429's I can find as 996TT fronts, but the .427/428? Any ideas? If it is of any help the rears that came with the set are the 996.352.425 and 996.352.426 variety used on a couple of models.


Thank you in advance, Ron

 

Look like pretty standard 996tt calipers to me.

 

they're definitely a LH/RH set because the pistons are oriented differently in each caliper. On multi-piston calipers, the smaller piston is on the leading side.

 

996-351-429 comes up as 996 4S/Turbo front left caliper

Perhaps the 427 is an older part number superseded by another part...

 

Thank you everyone, so when I put these up for sale would it be safe for me to saythey are off of a 996TT car?

 

I don't know that I'd say they came off a TT, but according to the part numbers they are compatible. If you're going for honesty, I'd list the pictures, part numbers and then state they're for 996TT or C4S with non-ceramic brakes
