Mopar_Earl if you do proceed with both the TV replacement and the front disk brakes would you consider the power brake swap first? I’m thinking there are a lot of forum members that would like to know if the power brake swap is acceptable with a drum / drum equipped car. I’m just thinking off the top of my head, but for a driveway stop or two wouldn’t a robust adjustment of the brake drag negate the need of a residual pressure valve for the front circuit? IIRC there was a poster that put together a front disk set-up from Ford pick-up parts that had the same wheel lug geometry.

I would believe the kit would be too touchy for drum/drum. Drum brakes work at lower pressure then disc. So you need less booster size and ideally a single booster. I will ask them if they offer a kit for drum/drum.

Residual valves are needed for all drum brakes. It keeps pressure on the wheel cylinder cups and against pistons. 10 psi. The treadle-vac has a residual valve as does all OE master cylinders on the drum circuit(s).

Disc brakes only need a residual valve if the master is at or below the calipers. It prevents the brake fluid from draining back to the master and causing more pedal travel. You would use a 2 psi valve. Now if you have a remote master like in the booster kit, you wouldn't need the caliper residual valve provided the remote reservoir(s) is higher than the calipers to prevent drain back.



Thanks,
