Okay I have done this swap before. I swapped my 91 EX sedan with DA rear Disk, and loved it, best upgrade i ever did. So im putting together another swap for my DX hatch now. I have everything but the proportion valve. On my 91 EX I had the upgraded EX front brakes so i just used the 40/40 valve. The DX has smaller breaks so was wondering what would be the best prop valve to use. I really dont want to change out the booster or master cylinder as they are both brand new units. In the long run its cheaper to swap to disk then it is to repair the drums , so they are gone. Just looking for an Idea as to what the best valve would be to use. I was assuming another 40/40.

 

40/40 is correct

 

i have a question.. i just got this 91 civic hatch with the rear disks and will wood breaks. and my ebrake doesnty work what so ever. really want to fix this. but i have no clue what to even look for back there. i just checked if the brakes were even grabing and they are decently the ebrake feels like its brabbing when i use it but its not att all when i take it out of gear ha, any ideas?
