Hi
The last time i did the brakes on my 98 3500 4x4 i just let gravity do it's thing.Seemed to work fine for me.
I started at the furthest wheel from the master cylinder,and opened the bleeder and waited for the fluid to come out,then moved to the next.I had changed both rear brake cylinders when i replaced all the shoes.
Seeing i work alone i thought i would try it and it worked for me.
