Need some help fellas with bleeding my rear brake.
'84 T-Type with Hydrobooster. Recently bought the car, brakes worked great so I never got around to checking the fluid level in the master cylinder. Went to pull it out of the garage and the brake light came on and the pedal went halfway down. Car still stops pretty good but I know I'm only running on the front brakes. Here's what I did:
-- Checked the levels in the master and I obviously ran the rear portion low, getting air into the rear system.
-- Filled it back up and bled the rear brakes. I get a good solid, steady stream of fluid from each rear wheel cylinder so I'm pretty confident they're bled.
-- Bench bled the rear portion of the master and when I disconnect the line for the rears at the master and pump it, I get a good solid, high pedal and solid fluid, no air. But when I hook it back up...and step on the brake...still goes halfway down and is mushy.
-- Jacked the rear up, and with the car running in gear, I step on the brake and the rear wheels slow down and stop for a second, then continue to spin with the pedal down. So, not getting any rear brakes.
-- Made sure the shoes were adjusted, slight drag on each drum, good shoes and hardware.
My assumption is that the prop valve still has some air in it and not activating the rear brakes. How do I bleed this prop valve? Seems to me my master cylinder is good and the wheel cylinders are good. I've had mostly older hot rods without prop valves so, it's causing me some grief. What am I missing?
Any help is greatly appreciated.
