Proportioning Valve Dilemma

[westie47]

When I got my 69 Coronet, it had manual disc brakes from a 74-75 Dart and a Wilwood proportioning valve. Im keeping the disc brakes and just ordered new brake lines, but I’m confused on what to do with the proportioning valve. If I keep the Wilwood I’ll have to modify/change the brake lines as it was mounted on the inner fender above the splash shield. If I decide to go with a factory type, can I buy the single drum brake one or do I need to buy the 3 piece disc brake proportioning valve kit!??? I just bought the factory replacement ‘drum’ lines.

The Wilwood adjustable valve would give you some front/rear tuning for your system over a stock combination valve. Also, the Wilwood will require you to modify your new lines by bending them to mate up with the inlets & outlets and possibly changing the flare nuts. (On my stock 72' the front and rear lines have different size nuts from the master cyl. to the prop valve. The wilwood probably has the same size all around).

If you are keeping discs up front, you probably should have ordered the disc/drum hard lines. Drum lines may not mate up right for a disc system. Also I believe you need a disc/drum stock prop valve and disc/drum master cyl. to ensure proper front/rear biasing, residual valve in place and warning lights functioning.

Thanks, most likely I’ll keep the Wilwood as that’s what was on and working. The disc brakes were hooked right up to the original factory lines and the lines were cut/adjusted at the proportioning valve. I guess I’ll solve that when the lines come in.
