I am doing a rear drum brake to disc brake swap. Does anyone know if I need to swap out the proportioning valve?

 

Yes you will need the valve from a disc rear. other than that your all set.

HTH

to be on the safe side i would get the one for the disk brakes.

 

When I put my 9 bolt in the car, I used the stock PV from my 10 bolt drum rear and they work great.

 

This isn't really a TPI question, but since I"m not a moderator, I don't really care..

Which disc brakes are you swapping too? I swapped to the early style cast iron brakes and I was rather dissapointed. I went from decent drum brakes w/ a functional parking brake, to a marginal set of discs w/ a non-funtioning parking brake. Not to mention, despite the lack of braking ablility from the rear, I now have to clean all four rims, instead of just the front I would say that unless your installing the newer aluminum PBR brakes, don't waste your time.

To answer your question though, use the disc brake prop valve.

 

First off, what the hell car is it on?? "Need the info..."

Year, make, model, stock setup?? Whatcha got? Can't read your mind...

This might help us to help you out.

Oh yeah..welcome aboard!!
