what prop valve comes on a 91 civic EX?

im using a 91 EX M/C and BB.... should i use the prop valve too?
its a 1991 si... changing over to rear discs...

any brake info is helpful too... not really sure what disc set up to use.. or what to change the fronts too...

yes ive searched... no real answer for what a 91 ex has

 

Hold on a sec, you have a 91 SI and your changing.... to disc brakes? If you have a 91 you should have disc brakes.???????

 

yeah, its a 91 Si. rear drums tho... i thought it would have 4 wheel discs... not sure which ones come with rear disc.... i def have rear drums tho.. and its def a si... sunroof, rear wiper... si door panels.... weird huh!

whats the prop on a 91 ex?

 

Only CRX Si's came with rear disc. You need a prop valve that says 40 40 on it. That is the proper one. Any car that has rear drum such as EX Sedan will not work. Integra or CRX Si have the one you are looking for.

just to confirm, you have a civic Si EF hatch right? not a CRX Si.


civic EX 4 doors came with a 3540 prop valve. but they also came with rear drums.

why? i have no idea. does it make sense? NO. its makes absolutely no sense. its got the biggest front brakes of any EF, master cyl and BB, yet rear drums, but its also the heaviest EF car and longer wheelbase. the DX 4dr came with a 3030 with base level brakes all around. the 90-91 CRX with slightly bigger front brakes (than base) and rear disc only came with a 2040.

nothing about the prop valve designations make sense.

all i know is that ppl keep wanting 4040's because they convert to rear disc. so i keep selling them. some have said their car brakes better after switching over. i have not heard a complaint yet from anyone i sold one to.

i highly recommend that you try to emulate the cars complete braking system, instead of mixnmatch and trying to make sense of something senseless.

 

any idea on wut the prop valve is on an 91-92 integra ls 2 dr

 

same as RS and GS.

 

ok cool. i have ls brakes all the way aorund and i have and ls bb, mc and prop valve that im gonna put on one day, jus wondering if it would help

 

thanks tyson... yes, it is a civic si hatchback.

so what your saying is if im using a 91 EX bb and mc... i should use a 91 ex prop valve?

not the 40/40?

not sure what brake set-up to go with... whats needed to convert to a good rear disc? and what can be done with the stock front set-up?

thanks for the advice
