...you don't absolutely need to change it if it is manual...We've been through all this before on the MMB...On '74 disc brake models Ford used the SAME prop valve as the '70-'74 drum brake models. I converted to disc on my '73 and used the stock "junction block" (which is all it is) with NO problems. The proportioning valve helps reduce rear-wheel lockup on these vehicals. You only need it IF you experience a problem with that, in which case, an adjustable prop-valve would be even better. I admit that '74 calipers were different from '75-'77 but the original '73 "junction block" seems to work fine with my '75 calipers. I assume he's going with the power setup since he got everything from the granada in which case he must swap the valve because the power brakes will be much more "touchy"...
: you need to change it, power or manual. It is pressure actuated and makes the bias in the disc system work properly.

: just brought disc brake setup off a Granada. Do I need to change the proportional valve too? The one off the Granada is different.
