I have got the problem,I can't pumping brakefluid to the axle brake cylinders.
I think it's,the Proportioning Valve.
It is very rusty,and in a bad condition.
It's hanging loose,and on a very strange place??
Here,I have cut the (front to rear)brakeline.
The NEW Proportioning Valve.
I take 1/8 inch copperwire,that's orginaly made for the electrical network.
A good alternative,for take the lenght of the brakelines
First I have bench bleed the mastercylinder,Then the prop valve,and then I start with the brakeline at the right rear> left rear> Right front > Left front.
Nice look,with the brass prop valve and copper brake lines
