Re: Dash parking brake indicator

Try to bleed with at least one in front and one in rear open at the same time. Gravity bleed will work fine for this. Do this diagonally. First open the right rear and the left front and let open for ten minutes or so making sure to watch the master cylinder level as to not deplete the fluid.Then repeat with the opposite two wheels. Post back with your results.

Re: Dash parking brake indicator

When you bled them, did you get good pressure/flow from both rears?

Borrowed a neighbor, did traditional bleed starting w/furthest away.

Didn’t help.

New problem, when left tire cut hard right brake hose is the limiting factor ! Stretched to max. Does steering have bump stops or is hose too short ?

There was no flow from FL when cut hard rt ! When I hit brakes hard on gravel dr (10 MPH) both front skid about 2’, nothing from back.

Re: Dash parking brake indicator

On a '69, the frame rail mounted unit is just a distribution block. There should be a delay valve mounted just below the master cylinder that allows the rear drum brakes time to engage before the front discs.

Re: Dash parking brake indicator

You've got the correct top side parts - i.e. the delay valve. Sounds like you've tried all of the bleeding suggestions - maybe the switch in the distribution block is bad or hanging-up. I would be inclined to remove it from car and try cleaning it out with brake cleaner. That would also give you the opportunity to bench test it. With it disconnected, out of the car, the switch should center itself and be an open circuit. You can test this by putting a test light or continuity test on the wire connector and the other end on the distribution block itself. There shouldn't be any continuity with this test.

A professional came by and bled brakes. Light was out for a mile or two, now it glows all the time even when brakes are not engaged.
