In my area, labor rates at the stealership run to about $70. An independent
will likely be cheaper, and all are required to post the labor rate in the
customer waiting area, or in a place where the customers can easily see what
it is.

The mechanics typically charge on a flat rate, where they refer to a book
tht gives them a number of hours for a particular service. The mechanic
strives to complete the job in the time alloted or less. If they manage to
complete the job in less time, they still get to charge the flat rate. (If a
job should take an hour, and they complete it a half-hour, they make money,
if they finish in an hour and a half, they do not charge more and they lose
money.) As a practical matter, they seldom take longer than the quoted time.

You'll find huge differences from place to place.  A Ford dealer here in the
DC metro area charges at least $90/hr, and the independents are pretty close
to that too.  Specialty dealerships like Mercedes, BMW, etc., charge $135+
I've been told.

Where my parents live in rural WV, larger dealerships charge $60 or so, but
one small, out-of-the-way Ford dealer charges $45/hr.  If I can plan my
repairs and maintenance in advance, I have them do my work when needed.

There is no standardized labor rate.

Without knowing exactly how much of the rear brake line was
replaced and how tidy the finished job was, it would be
impossible to say whether you were treated fairly.

$75 is pretty close to what I charged for the 92 F-150 I did
about a month ago, ABS modulator to rear axle flex hose.

That same job on a Toyota car with dual brake lines would run
over $200

The dealer I go to charges $72 per hour. The independent up the street
charges $65 per hour, and the better thing is, he only charges actual
hours required to do the work, not the book time!! Some things are
still done better by the dealer.
