1971 Dodge Demon Hemi install

First they said rotate the rear housing so the calipers were horizontal
during the bleeding procedure. Got pedal but after it sat a bit it would
go right to the floor.

After 3 (very) Strange master cylinders (both bore sizes) he put a new
style Mopar one on............instant hard brake pedal.

Funny, I talked with him for a long time before convincing him to go with the Mopar one....... the plumbing is easier and well, better pedal!
