rear drums to disk - 95 civic dx hatch

As the subject says, I have a 1995 Civic DX hatchback. The previos
owner of the car, my roomate, had the rear drums converted to disk
breaks. I remember at some point after they were converted, I helped
him change the pad on the back, but the new pads caused the brakes to
seem like they were dragging all the time, you could even smell the
brake dust after just driving it down the street from the house, so we
just put the old pads back on never messed with them again. Well now
the car is mine and the break situation has always bothered me. I have
not noticed any problems with breaking, but I still want to rectify the
situation. Now since it had drums then the factory proportioning valve
on the car would be set to always have few pounds of pressure on the
rears at all times since shoes always need pressure to hold them next
to the drums. I'm not sure if the valve was replaced, and I know the
one that is in the car now is not an adjustable one. Is there another
honda of the same erra I can go to a junk yard and get it's
proportioning valve that was desinged for 4 wheel disk and put it on
and work fine, or what other options are there.

the correct proportioning valve is absolutely vital. especially for
safe braking in the wet.

for integras with the 10.25" front disks & rear disks, the proportioning
valve has "4040" stamped on it. for ordinary civic dx's with 9.5" front
disks & rear drums, it's "3525" iirc. i think you want something like
"3540", but check the size of your fronts. if you can get one from the
95 si, you should be ok. if you get the correct valve, lease post the #
to group for reference.

i think civics, preludes, crx's, integras, 88 through 95 had the same
proportioning valve style, only valved different per the number stamped
on the side.
