The source of compressed air needs to be regulated way down, so you don't
blow the plastic reservoir off the master cylinder (DISASTROUS and
DANGEROUS!).  The pressure-type power-bleeders have a guage so you don't
over-pump and have problems.  The master cyl., lines, hoses and wheel cyls./
calipers withstand about 1500 psi in normal use.  But, the reservoir never
sees any pressure, except atmospheric, as it's vented to outside air.
  The pressure bleed method is superior to all other methods (in my
experience).  But you MUST exercise caution in aplying pressure to the cap/
reservoir assembly.  Regulate it to 15 psi or less, to be safe.  As I've
heard said, "once you power-bleed,  you'll never do it any other way!".

HTH,
