ah ha.............
so the brake MC isn't new, or replaced a couple of times in the last year or
so.
here're my 'rules'........
if it bleeds right ........that is, no air gets pumped in .............it
bleeds well to all 4 wheels............and your sure there are no restricted
or collapsed hoses ( very rare in my experience ) ..........and the pedal
still doesn't seem right ( and you've done the brake booster test for it's
function - I seldom condemn a booster ) .............it's the brake master
cylinder.
you know what 'right' feels like ..........good firm high pedal, and you get
progressively more brake action as you apply more pressure to the pedal.
If it bleeds right .........and things are mechanically right in all 4
wheels..........and you don't get the brake action you feel like you should
from pressing on the brake pedal ( and you don't have glazed shoes or pads
that can't 'grab' their friction surfaces well ) ............and the booster
passes it's test..............brake master cylinder is indicated.
and I still don't trust a pressure bleed as much as I do a manual pedal
bleed............cause you can feel what the MC is doing in a manual pedal
bleeding procedure, or *I* can anyway !
hope you get it.
given your big trip coming up .........and how much you've worked on
this........seems very justified to invest in a new brake MC to me at this
point.
