Actually, the hoses only last about 12-15 years before the inner lining
starts to degrade - then they allow the fluid to be forced to operate the
brake but the degraded lining will not allow the fluid to move back away
from the pistons when the brake pedal is released. This causes the pads to
remain lightly in contact with the rotor - rapidly wearing the pads and
often damaging the rotors. It's often hard to know the hoses are bad - but
the external hose will get severe cracks - mine were visible when the car
was raised on a lift and the wheels were hanging down - the cracks were very
visible.
It would also reduce the fuel economy as you suggest -
Good luck -

Improperly adjusted valves can reduce it a little.
I'm thinking that if he had a brake hose acting like a one-way valve
it would have killed the pads a few times in the last couple of years,
but I suppose it wouldn't hurt to jack up the wheels and give them
a spin to find out.
