It's a good idea to have the entire brake system flushed to get the old
brake fluid out and new in. I think that's what they're wanting to do to
your truck. Brake fluid gets dirty and will absorb moisture contaminating it
and lowering the boiling point, making it less effective and corrosive to
your brake parts.

My '99 Chevy truck has 69,000 miles on it, when I replace the front pads and
rotors this spring I plan to flush the brake system then.
