brake pressure differential valve

[67 short box]

after an ill fated attempt to install front disc, I have all drums on now. the brake light is now on and I forgot what to do to get it off. I know the valve works because I had it off once and fixed the piston. 67 thanks....

I believe once you re-center to piston in the valve, it will go off.
