Hybrid240z Posted June 27, 2012 Share Posted June 27, 2012 I've searched online and on Hybridz and this is what I have found so far. S13: 89-94 240SX S14: 95-98 240SX S13 and S14 rear calipers appear to use the same brake pads, from online pictures they look similar with some small differences, and rear brake upgrade kits for the 240SX appear to fit both S13 and S14 models. The Modern Motorsports (MM) site indicates to use S13 (89-94) calipers for the swap so these are the ones I currently have. Online info indicates that the S13 calipers have a 34mm piston, and S14 calipers have a 38mm piston. Is this true? Can someone confirm this? Also, has anyone been able to use S14 calipers with the MM kit? If so were any additional mods needed to use the S14 calipers? The only reason I will try to use S14 calipers is if the piston in them is truly 38mm. I measured the S13 piston and it does appear to be 34mm. As long as i'm asking these questions, what is the piston size in the 280ZX and Maxima calipers that are also used in these swaps. I've found too much conflicting info online. Thanks.
