For bleeding brakes, a separated tool is use to do maintenance on brake
lines. You can get or see one at a auto parts store. The brake booster
should start working any vacuum of 12 in.hg. or more. Best if the vacuum is
held at or above 15 in.hg.
If the 27.56 in.hg. refers to the brake booster, than it may be a print
error, it may be 17.56 in.hg. for the brake booster.
