    We are about to do a rear disc set up on my friend's 93 civic and mysteriously enough his master decides to take a shit. so we're gonna go with a bigger master and i was wondering which ones will fit on his stock booster? i was just going to go with the 95 EX master but if there is a bigger better one we could use, please let me know. the lx one is a 13/16...i believe the EX one is a 15/16...i know the integra ones are 1's but i don't know if it'll fit his booster. anyone? thanks

    You can get a 7/8 off a 90-91 civic Si, or I believe the 91 ex is a 15/16 and bolts right on. Most of the 15/16's I have seen other than the EX, have the ears clocked the opposite direction and require correct the booster to bolt it on. Right now I am using the 91 Civic Si MC on my VX booster and it is pretty good, pedal travel is not too bad, and it stops well, when I get off my lazy ass I am going to put in my GSR booster and 15/16 though.

    I also got mine from an 89-ish prelude. it's 15/16. My 95 EX coupe came with a 7/8. perhaps the EX's with ABS have a bigger MC.

    UPDATE: now i know why you used the 91 EX MC, John. the fitting for the hard line on the 89 prelude, that is farthest from the booster, is parallel with the other fitting. on the dx's and lx's, the MC has the farther fitting slighty angled upward. i had to bend the hard line down to get it to fit the prelude MC and i almost kinked the whole hard line. didn't want to revive this thread but i thought everyone could learn from my mistake.
