will a 4 door gsr master cylinder and brake booster fit on my 1991 crx? i see that one brake line is on the opposite side of the master cylinder will i have to run a new line? and the brake booster looks like its larger in diameter. will there be any clearance issues? i am upgrading to gsr brakes. thanks

 

I used 92 GSR brake booster and master cylinder. Everything lined up and no new lines being made.

 

i did the same but w newer gsr booster and master no mods of the lines needed at all and i suggest doin a proportioning valve too off a civic si this will make a huge difference
but just check it out

 

the one im using is from a 1995 4 door gsr. just like this one.

Looks like what I got; I'm using a 1" ABS one; had to swap the MC and BB, bend one line and use a M12/M10 IFF adapter.

 

Yes you can use the 4 door they are all the same fit. Why don't people do any searching.

 

i tried for a while but i guess i didnt search the right keywords.

 

sory man thats wierd i had no fitment issues at all

 

Have a pic of that adapter?
I also have the 1"ABS but i had to reflare the line with the bigger m12 fitting.
So you did not flare anything??

 

Nope; didn't reflare anything. I was about to but stumbled upon a "M12 to 3/8" IFF adapter"; just thought I'd try since the M10 fittings are almost the size of 3/8" fittings....and it worked perfectly!
I had a couple of guys tell me that it was wrong, doesn't work(crossthreaded), will leak, etc....but I know when a bolt fits a nut perfectly as I work in the manufacturing business and the adapter specifically said it was for inverted flare fittings and was shaped so.

After looking up the PN online, I found out it's actually a M12/M10 IFF adapter and it's just mislabeled. I PM'd you the pic though; here it is again:

 

K2e2vin thank you man. thats exactly the info i was lookin for. greatly appreciated

 

Where can you buy the M12/M10 adapter?
