Re: bleeding problems
That wire is for the "Brake" light on the dash, and it warns of low brake fluid/pressure.

Re: bleeding problems
the wire does not warn any of that so i been told by an mechican the wire on the prop vavle is to let you know that the prop vavle has been triped hook the wire back up and if the light in your dash is on the vavle is closed. i've been told going down the road hit the brakes hard but in your case? i'd not want to go down the road. someone else will have to answer that. but the vacuum bleeder can pull the vavle shut so i been told if thes no fuild in the lines just air

Re: bleeding problems
i didn't mean to say only air, no fluid. there is some fluid but it's mostly air. could it be that i didn't completly bench bleed the mc? i was told even if it wasn't completly bench bled, the vacuum bleeder would take care of it. is this true? if the valve in the prop is shut, how do i open it? thanks alot
