So I've gone through changing my green tag master cylinder and brake booster with the yellow tag system and changed a number of brake pipes including the one from the bias valve to the rear.
Got to bleeding the brakes today and couldn't get anything from the rear left drum. Thought might be full of crud so I unscrewed the entire bleed nipple and got nothing out of it?
Even when pumping the brakes after bleeding the rest of the system. Was using the gunson pressured bleed tool and then tried the old fashioned way of pumping the peddle.
They were only changed a few years ago too 😭

Chase the air along the pipe. Crack a union a couple turns, pump til either : you hear air or see fluid from it.

I would suggest cracking the side that is not giving fluid on the bias valve and see what, if anything you get from it.

If left open for anything longer than an hour with a full master cylinder i would say bias valve was yer issue..

Good luck

Cracked the other side and got all or at least most of the air out through that side so the pedal is nice and stiff.

Sounds like another collapsed rear flexi hose again.

They swell up inside with age and the fluid won`t get through.

Could always try putting the bleed nipple where the feed pipe goes to,the dry wheel cylinder.

In essence bleed with no pipe to that corner see if you get a good pedal...
