Brake Master Cylinder Upgrade for 1992-1995 Civics

Taken from H-T with love.

Original poster B18C5-EH2

"*I'm sure I'm not the first guy to discover this mod, and I'm not trying to sound as though I came up with the idea. Another H-T member told me that they've heard of this mod, so I just took it further and actually ordered one at my shop and put it on a customer's 1993 CX to test it - it works.*

Well for all of you guys running 4-wheel discs and/or bigger front discs that need a bigger-than-stock 13/16ths M/C, there is a true bolt-in replacement for sure.

I heard a rumor that a certain 15/16ths m/c just bolted up, and it's true. I ordered one the other day and my shop put on ein a 1993 Cx hatch. It's a:

1991 Honda Civic EX 4-door master cylinder.

The part number from Honda is 46100-SH4-A11. They probably won't stock it, but it only took me one full day to get the one I ordered.

This m/c bolted right up to the stock Civic booster, so no more trying to find an Integra booster and m/c combo!

The only thing is that I cannot say which stops better - my Integra RS booster and m/c combo, or the 1991 EX with stock Civic booster because the CX we did the EX m/c on still had stock brakes to be upgraded with all Integra discs later.

The 1991 EX m/c is the same 15/16ths like my Integra Rs, but the ears are located the same as the stock Civic so there's no need for the Integra booster. the Integra booster is larger volume, but I've yet to determine if the Teg booster makes much difference over stock until,this CX guy gets his 4-wheel discs and 40/40 prop valve.

So if you want an easy m/c upgrade with no booster worries, try this one."

my 98 still came with a 13/16 M/C. total bull****! the car grew, why couldn't the master cylinder. it's like a grown man with a baby's dick. I swapped in a 15/16 ... and now I'll prolly swap that out for whatever the Civic Type R has... 1 1/16 I think.

j00 size is cast into the side of the cylinder... on the front side of it, on the side facing the outside of the driver. 15/16 for the Si - at least my buddy's 93 Si coupe.

CX and other low level Civics should have 13/16.

Does your buddy's 93 Si Coupe have 4 wheel disks?
