I just got a complete rear disc conversion for my ex coupe. I would like to know if the 4040 prop valve is a necessity or optional? I would also like to know if I should replace my MC/BB, if so with what make and model?

PS- I did search...TIA

 

Yes, you should definately look to use the 4040 prop valve. Your stock BB should be fine, but you may want to use a 15/16 MC for a more desireable[sp?] pedal feel.

 

Ok so the 15/16 master cylinder is fine with my stock bb?

Do I reuse the integra brake lines?

 

Yes the BB will be fine. Dont know about the brake lines though...

 

Just to clear up any confusion...I was talking about the rear brake lines on the trailing arm...Do I use integra lines or civic coupe wit rear disc brake lines?

 

integra coupe lines and civic ear disk lines are the same i believe. i ordered a set for my car, 95 civic ex and my bros, 00 dc2 teg and they were the same.
i actually am using my stock prop valve, the 40/40 isnt necessary to make the system work, but with out it you are alot more likely to lock your rear tires up under heavy braking.
also, i am pretty sure the civic ex stock master cylinder is 15/16. you can also use an s2k master cylinder and brake booster if you wanna get a lil fancier
