First, don't consider Dot 5. It's silicon and must be used with a clean
system (no old fluid at all, anywhere!). Even after flushing the system
several times with alcohol, some of the old fluid will remain and mix
with the silicon to form bondo. Dot 4 or Castrol is good stuff so get
a "MityVac" to pull it through the system. Start at the farthest point
from the master cylinder (right rear) and draw out brake fluid and air
until you get fresh fluid out. Then go to the left rear and repeat,
then right front and left front.
