I replaced the booster unit and am bleeding out the system, but have
never done a truck with RWAL before (97 Dakota).
When I got to the left rear, an ounce or two of fluid came out (using a
Mityvac vac pump...not pedal pushing)...then nothing.
According to the shop manual, the little ball bleed valve on the end of
the RWAL valve do not need to be open when using a vacuum method.
So what's the problem?
Do I need to bleed the combo valve and the RWAL valve, and if so, can
that be done with a mityvac? (don't have someone around to pump the
brake pedal.) I did not bench bleed the master cylinder before putting
back onto the new booster.
Any advice would be appreciated.
