the prop valve is the valve that proportions how much fluid to send to the front brakes and how much to send to the back brakes. what proportion. this can be acquired from most integras, as well as 96-00 civic dx vehicles. there are others but those are some common ones. i actually have an extra 40/40 valve off an integra for sale if you would like to purchase it. i can send you some pictures.

brake lines - yes you will have to replace the brakelines. the soft lines that were on your drum setup will not fit the rear disk setup. almost ANY brake hose from a honda/acura will fit. you need soft lines that are about 24" long. the ones i used were actually from the front brakes of an s2000 haha. but they all have the same thread pitch and size and are almost all the same lengths.

if you need any other help i'd be glad to assist. I'm running 10.3" with ITR calipers up front, the 9.5" gsr rear disks, and a 1" mc and booster from a gsr, stock dx 4040 prop valve. all in my 97 dx.
