Question Re: Dual chamber master cylinder for drum brakes

Now wait a minute ...

First you say there is no need for a PPV on a car (DRUM/DRUM I a$$-u-me), then you state you only used a distribution block.

Now you are saying you are using an ADJ BIAS VALVE on your DRUM/DRUM fully opened?

You have a DRUM/DRUM DUAL RESERVOIR MC upgrade?

The last photo below is a FORD (Weatherhead) free-standing PDV (Pressure Differential Valve/Distribution Block of the seventies period (no PROPORTIONING/METERING VALVE). If you do not want the WARNING LAMP, don't use the circuit.

EDIT - ONE MORE TIME

Are you saying you have an early disc/drum upgrade with no valving on the street?

You know, this why SEMA has to continually fight the FEDS who want to put a stop to owner repair/modifications.
