Rear brake bias problems - Viper front calipers with rear drums

first that switch on the wildwood prop valve is a brake light switch ( not a warning light switch )

Well that makes me feel pretty stupid... No wonder the light turns on when I hit the brakes!

I'm sure the lines are plumbed correctly through the valve. That's why I was surprised that I could still lock up the rear brakes.

I'll try some smaller wheel cylinders in the rear and re-bleed the whole system.

Vitamindart, what size master cylinder are you using?

Thanks everyone!
