I have always bled them the normal ay....A power bleeder would work great if you can get access to one!
Didn't realize that Rick.....But makes total sense, now that you mention it....Thanks for the tip :tuBleed normally, don't step hard on the pedal until the bleeding is complete.....Reason is, there's a shuttle in the valve that will close off the side that's not bled, if you apply the pedal firmly before you're done.
I was in the trade when the dual system came out, and we had a spring clip of sorts, that held that valve like you say. The clip was lost before anyone could use it, so we never used one. To clarify, don't fill and bleed just one end of the system at a time. Doing so will cause that valve to stay at one side, and it's a bugger to center. This is why we suggest to go slow and easy on the brake pedal, until you get most of the air out of both ends. Once the pedal firms up, you don't have to be as careful.I'll try that Auggie. Thay makes sense to me. Could get messy out there.
An article on line says to use a clamp and a block of wood to push the valve in (open) while you bleed them the first time.
Only one article referes to doing it this way. It claims that it lets fluid move evenly, the valve is supposed to keep fluid up front in its normal position.
Anyone hear of this?
