No Fluid Through The Brake Lines

[scodari]

Hi All:

My son and I are trying to get a 70 GT on the road. We have had it off the road for two years...I don't know how long it was off the road by the PO. We've had the rotors turned and have installed rebuilt calipers but we get no fluid through the lines when we attempt to bleed the brakes. I thought it was a bad MC, so I disconnected the lines at the MC and I get fluid flowing from the MC when I press the brake pedal. I have attempted to blow air through the brake lines just to test if it flows freely but not luck with the air either. Do you think the lines need to be replaced? I've never done this before; do you run a new line from the MC all the way to each wheel?

Have you checked the flex lines? They are notorious for becoming blocked. If you can't get air through it something has collapsed.

I would suggest getting new brake hoses, there are three of them, one at each caliper and the third one just forward of the rear axle. They have been known to become deteriorated and act like one-way check valves, either allowing fluid to flow out to the brakes and not allow the brakes to retract or to restrict flow completely, as in your case. Opel GT Source --- Welcome has all three hoses and will usually get you same day shipping. Check out their on-line catalog. HTH.

did you disconnect the rubber flex lines from the steel ?
brake hose's are a very common problem with older cars

The rubber flex hoses at the front wheels and back differential can go bad and collapse. I had trouble bleeding my front brakes after I rebuilt my front end, I had to open the bleeder valves on the back wheels to bleed the front.

Wow, four of us posted at the same time with the same answer, that has to be some kind of a record.!
