If you have a proportion valve, it may be somewhere in the line to the rear brakes.

So IF it is as you say, what would the affect be when applying the brakes? My rear brakes don't lock up, nor do the front when mashing the brake peddle.
Note: I replaced the solid brake line that goes along the frame next to the engine back to the rear axle...no proportion valve found. I have not seen another inline valve. Are you saying that I'm getting equal pressure to the front and the rear brakes?
Sounds like when the previous owner installed the power brake booster and front disk setup he left the drum brake "differential" switch intact and neglected to install a disc/drum P valve.
I would put in a new Disc/Drum valve, but I'm considering converting the rear to disc and don't want to buy the valve twice. What P valve would you recomend for Disc/drum?
