does the pedal pulse at all when you apply the brakes? sounds like the brakes are slightly out of adjustment thus causing the pumping to take up the slack, when the rears were adjusted did the drums appear out of round at all or have you turned the drums and rotors lately to make sure every thing is proper that way? if all of that checks out then I would start by rebleeding the master cylinder to make sure no air is trapped in it. followed by bleeding the entire system.

if we're not supposed to eat animals why are they made out of meat?

Hi Speedwrench,
No pulsing; did re-bleed master but not the rest; will do. also will adjust rear drums again. How to check vacuum pump output? Possible lack of to booster? Thanks Ron
