im doing a rear disk conversion on my 92 cx. im swapping in 92-95 SI disc brakes. im just curious if i can still use my same prop. valve or if i will need an si one? there not that big of disc or calipers so i dont see why it would need a bigger valve, but i dont want to swap it in to find out my brakes wont release or stop properly. and also can i use the lca`s from my cx, or will i need si ones as well?

 

Yes, you need the Si prop valve.

 

does it matter what year it came out of? like can i use an ek prop valve? or does it have to be EG specific?
