ok, the mastercylinder has 3 lines coming out of it one that goes to the rear
one for the left front and one for the right front. at the mastercylinder i
bled all air out of it...there was lots in the line that went to the rear of
the bus and some that went to the driverside front. so i bled all the air out
at the MC then i went to the right rear. by i, i mean a friend of mine. we did
the ol' tube in a bottle of fluid trick. got some small bubbles out of the
right rear, next we went to the left rear, man oh man there were some bubbles
after we pumped it two or three times. then we went to the right front, it took
forever to get to fluid (keep in mind i have already bled everything 4 times
before this point) then we went to the driverside front. got air.
pedal then worked but not impressive. so we decided to pressure bleed the
system at this point pump, pump pump HOLD!!! right rear spit out air twice then
solid fluid shot out like a water cannon. pump pump pump HOLD!!! left rear did
the same. moved to the right front it took 5 tries to get the final air out of
it. then we moved to the right side. fluid came out like an old man trying to
pee, slow and it dribbled for a bit. we did that for a bit and then all of the
sudden the fluid shot out so strong it hit the other side. tightened it up
the brakes are great, they don't give way but there is still a slight
problem, if i come on strong at first they work great. i even tested them and
managed to get all four wheels to lock up, if i eas on them the pedal goes down
about half way till it works, and if i just gently push it in it still goes to
the floor.
what do ya'll think? mastercylinder needs replaced or still some air hidden
somewhere? i am buying the appropriate tool from harbor freight this weekend
and will try it again but i am leaning towards a mastercylinder. like a friend
once told me "rebuilds only last so long"
