Bleed the M/C, BEFORE installing on the truck. Instructions should be in the package, if not grab a Chilton manual at the store. You will save yourself a LOT of work if you don't introduce anymore air into your lines.

Always start bleeding the wheels at the farthest from the M/C and end at the closest.

You shouldn't need to bleed at the M/C if you bench bleed and then bleed at the wheels.
