[Spridgets] Brake Bleed p.s.

[Michael MacLean]

Rick,
     I don't think the new master is leaking internally.  I drove the car
for over 5 hours yesterday on my way to and from the shop to swap out
clutch slave cylinders.  The brake pedal goes down almost half way then
becomes solid and the brakes work as normal.  It can be pumped up once or
twice and become solid again.  The system was pressure bled multiple
times..  The mechanic and I have come to the likely conclusion the new
brake shoes in the rear are not contacting the brake drum along it's full
surface.   No one does brake shoe arcing anymore.  When I step on the
brakes only a partial part of the brake shoe contacts the brake drum.  At
the rate of wear on the rear brake shoes, I don't know if they will ever
get full contact.  At this time the car stops quite well, but I credit the
light weight of the car for this.  If I was getting 100% out of the rear
drums the braking would be much improved.  That's my story and I'm sticking
to it.
