Ok so i've actually searched around before i decided to ask and i found several different answers..I have a 98 EK and plan on doing the rear disc swap from a gsr so i have the 2 rear trailing arms and the e-brake cable... and a 40/40 prop valve... if i am only changing the rears will my MC/BB be fine? and will the prop valve mount up properly or am i missing brake lines?? since i've seen some post say i need the stainless steel brake lines n others say i dont... thats why im asking.... i kno if i decide to upgrade the front brakes to teg brakes i will have to slap on a teg mc/bb also but for the moment just the rears... so will my current mc/bb do and do i need to pick up brake lines??

 

this isn't really answering you Q ,,but I did front/rear gsr brakes on my 97 ek and left the prop valve alone ,didn't have any problem but at the same time I dunno if by doing this that I have hindered my braking performance or not

 

All rear disc setups are the same - gsr isnt special.
If you have a hatch, you dont need to change the prop - its already the same as the 99-00 em1.
Recommended that you use a 7/8 MC/BB combo (stock on ex/si).
You never NEED stainless lines...they dont do anything but increase pedal firmness - no increase in performance.
If you decide to upgrade to integra fronts, you will need at least a 15/16" or 1" MC.

 

Your stock brake booster will be fine. If you got the Civic proportioning valve, you shouldn't have any problems with brake lines matching up. People say you need stainless steel brake lines as in from the hard line to your new caliper because the disc brake lines have a different fitting on the end. Since you will have to get new rear brake lines in the back , you might as well upgrade while you're at it.

the 40/40 prop valve i have is from a teg i think not sure i just kno its a 40/40.. and thanks the different fitting was the main question... now which line would i need... would i just go to a kragen or somethin n ask for the rear brake lines or how would i go about getting them.. since i dont wanna start and not be able to finish due to missing parts

 

just get rear brake hoses (lines are hard) for any civic/integra/del sol that has rear disc
ebay or the classifieds here are your best bet
