Ron,
It's damned adequate for normal use provided the master is level (like it is
on the trailer). Bleeding with Dot3/4 is interesting. One would think the
bubbles would just flow up hill and it would bleed itself. Maybe by the
turn of the century it will.
We do as the bike guys do on an initial build, pull off the master, pass it
out through the wheel well fire wall, screw in the funnel, then push fluid
with a syringe up from the caliper and out of the master to a cup. Once
filled to the top, the air is gone. Screw in the cap and the handle should
be dead hard. No sponginess. Then you are good until the brake pad wears
down. To adjust the level, install the funnel, leave the master in place,
put the plane tail up to allow all the air to come out the funnel cup and
carefully add fluid. Suck out the excess and seal it up..
Regards,
Bud Yerly
