Bullitt

Since my drums have gone bad in the rear. I´m going to swap rear disc brakes on my EK Hatchback. I have a EJ9, basically the same like the USDM "DX" model. I have no ABS. So there are six brake lines going into my stock proportioning valve.

Which prop valve do I have to use with rear discs? I know it must be a 4040, but will a valve from a 99 Si work, because the car has ABS from Factory?
Help me out, this is the last thing that is missing

you can use any 40/40 prop valve.

You need the prop valve out of a 99-00 Si w/o ABS. I know they exist because I have one. As far as I know its the only prop valve that has the proper orientation for your hard lines. to tell the difference, the ABS prop valves only have 4 port where as the non-ABS have 6 ports.

EK DX and EK Si are the same prop valve.. you switch nothing..

if you dotn beleive me go look at http://www.slhondaparts.com and compare part numbers for all 96-00 honda civics.

46210-S04-902 is the part number for the 96-00 non abs prop valve.

v4lu3s is 100% correct. I'm doing my second rear disc conversion this week, and this time around I know that I don't need to swap the prop valve. You definitely want to upgrade your MC to 7/8 (stock 99-00 Si MC size), and you don't even need to switch the booster because the part numbers for the booster are the same for all 99-00 civics. Switching your stock 13/16 to 7/8 master cylinder should be a direct bolt in, so no need to worry about bending and flaring custom brake lines.

is the diameter of the booster bigger on the 99-00 si ?

ej0513

Si MC is either 7/8ths or 15/16ths.. its wierd.. some people claim to have one or the other, so i guess they are not the same.. but your best bet for a complete bolt in is to use 98+ Integra MC and BB.. its 1 inch, but i myself used a DC5 15/16th MC and BB and it worked great.. it just needed a little bending of the lines.

I´m still confused. I got the part number from my stock brake valve, its 46210-S04-801

The other parts listed above have the ending 902.
Does anybody have infos about this part? Can I use it, or is it the wrong thing?

v4lu3s

the part number i listed is for the 99-00 civic si, as well as all 96-00 hatchbacks, the sedans and coupes may have diff part numbes.

ej0513

all 96-00 hatchback, coupes and sedans have the same proportioning valve.. sooo.. no need to change anything when doing a drum to disk conversion.

v4lu3s

the coupes and sedans Do have a diff part number indicating there are different revisions out there...

ej0513

^oh.. my bad.. i was going off the fact that my 98 hatch and 99-00 Si coupes had the same.. i just checked slhonda.com and the part numbers are different.. as for the actual difference.. i dont know.. and BTW when i checked the part numbers it was for DX models.

ej0513

but back to the original posters question, which has nothing to do with sedans.. he does not need to change the valve.. [/thread]
