Bleeding Brakes

The fluid is going thru the main prop. valve but stops at the second one. This valve is called a hold off valve it delays the rear brakes a split second to prevent lock up under hard braking. It seams that I don't have enough pressure to open the valve. Anyone

Okay so we're talking about the valve at the back end. Disconnect it from the lines and have a look at it. I've seen some that employ an orifice that limits the speed that the fluid can travel to the brake cylinders. Either way make sure it ain't plugged.

P.S. I've bleed my share of brake systems and getting oil to the 4 corners has never been a problem.
