My 2002 Ford E150 van wears out its front brake pads at about 20,000
miles. The front wheels constantly exhibit brake dust on them. It
appears to me that the front brakes are constantly engaged, to some
degree, on the rotor and are constantly wearing some.
Back in the 80's when I worked as a curb mechanic I was told to leave
the front bearings a bit loose so the play would allow the rotor to
wobble a little and kick the caliper pistons and brake shoes back off of
the rotor when the pedal was not applied.
Is this still a good approach with today's finely machined bearings or
is there a better way to minimize brake ware?
Thanks,
Charlie

I would suggest that you check your master cylinder pushrod length. If
it is too long the master cylinder won't close all the way and it may
very well keep some pressure on the front brakes. I would adjust the
wheel bearings per factory specifications. Running a bearing loose is
only going to cost you money for new bearings and possibly a new
spindle....or worse.

no it is not
are the rear brakes working correctly??
if they are not the fronts will wear faster as well if the rotors were
replaced or not makes a difference ar4e the calipers siezed at the pins
which is common
time to take it to a good shop that will do a complete inspection just to
make sure

rear disc or drum? if drum, then adjust your rear brakes until there
is a slight drag
this will ensure proper braking 70 30 percent
also raise the front wheels and apply the brake then check for drag ,
you may need caliper hoses and a good slide cleaning also new pads
have been painted where they sit on the caliper brackets remove this
paint it will cause pads to stick not allowing retraction
never loosen your wheel bearings as their job is to transfer weight
from chassis to wheel. Change the hardware and remove any rust build
up on caliper brackets to minimize drag.
