I know this has been covered more than enough times. But to help clear things up do i need to change my prop valve (currently 3040) to a 4040 when i convert to rear discs??

Reason why im asking is because i read on so many threads that it IS required.. Then suddenly its NOT required lol..

Thanks in advance

- Sun Jul 07, 2013 3:42 pm #333955 YES, change it, but you don't need too

the reason for swapping to rear disc is for better braking correct?
so you would wanna swap out the prop valve to a 40/40

if not swapping it out, doing a rear disc swap is pointless,
a 30/40 would work, but not to the rear disc full potential

the purpose of the prop valve is to distribute the braking force
between the front and the rear.. so now that you gonna have rear disc
you want more braking power to the rear, this is the reason why you swap it out...

regardless what you have drum, or disc, the front will always do most of the braking

edit: you sure its a 30/40.. iirc the stock eg ones were 60/30

- Mon Jul 08, 2013 3:01 am #333969 My '95 DX coupe had/has a 30/30. I swapped to discs in the rear and didn't change it out and it feels fine.

I have heard that if you already have a 30/30, swapping to a 40/40 results in no noticeable difference. I wouldn't know though as I just retained the original 30/30.

- Mon Jul 08, 2013 3:23 am #333973 im guessing that the 30/30 would be just as good as a 40/40 because it splits the power evenly?

again just guessing

95 Civic Coupe DX - d15b7 - some mods nothing crazy - My 5th EG
98 Jeep Cherokee 2 door - little lift with 31s 4.0 5 speed

- Sat Nov 23, 2013 3:53 pm #339244 any non abs with rear disc civic or intergra

- Sat Nov 23, 2013 4:47 pm #339245 ok cool but iv never delved into anything reguarding mechanical stuff so what year cars will I be looking for? when was abs introduced and in what models so I can avoid getting the wrong one?? there are no pics of such items anywhere so cant compare iseem to be going round and round in circles with this

thankyou

- Sat Nov 23, 2013 10:59 pm #339265 90-01 integra non abs

92-00 civic non abs w/ rear disc

- Sun Nov 24, 2013 5:24 pm #339283 Uk models are either an esi or vti but both can have abs if theyre a later spec car. There's plenty of imports or integras that have the same prop valve
