[V8] brake bleeding

[Ingo Rautenberg]

I'm no fan of vacuum bleeders. I would go with a pressure bleeder (8-10 psi)
through the brake reservoir. Start at the right rear, left rear, right front
and left front. Make sure you have enough clear tubing to go at least a foot
or two above the bleed nipple to make sure you don't see any more bubbles. I
like to switch between an ATE blue and ATE clear, so I know I'm using fresh
fluid.

Anyhow, that's my recommendation. Otherwise, you could have a bad master
cylinder, maybe?
