yalan 0 Posted February 2, 2005 can anyone tell me what size the piston is on the 16v calipers? Just want to work out whether the master cylinder is more up to the job of driving a set of front or rear 4-pots off a porker. Cheers. Quote Share this post Link to post Share on other sites
ben16v 0 Posted February 3, 2005 dunno the piston size but i think the master cylinder is 22mm if thats any good to you? (ignore me if not! :lol:) Quote Share this post Link to post Share on other sites
yalan 0 Posted February 13, 2005 cheers for the MC size info..... but am still looking for piston size ...... Anyone got a spare one sitting in their garage they could take a vernier to??? EDIT: measured my own: 53.8mm (ISH) Meaning that boxster / boxster S / 996 rear calipers are absolutely no use due to their piddly small pistons - almost half the combined fluid volume they'd need to be as useful replacements for OEM parts.
