Has your mechanic checked rotor runout with a runout gauge? Considering
the cost of replacement, it would be worth making certain the rotors are
in fact out-of-true before committing to the work.

typically, this is solvable by cleaning the wheel interface, disk and
wheel, then smearing a little anti-seize. re-torquing the lug nuts is
critical too. needs to be in the correct sequence, with a torque
wrench, in a 2 or more step process. it's very common for shops to use
air tools when tightening and what you're experiencing is the result.
last thing - try the above and see if it works. if not, go ahead and
get the rotors replaced. in my experience, once a disk is cut, the
problem becomes much less soluble.

Excess heat especially when combined with uneven lug nut torque can cause
problems. Every source of heat build up needs to be checked and eliminated
before the rotors are replaced or it will happen again. Hoses can develop
broken inner linings that act as check valves and do not release applied
pressure much like the check valves in our veins. Frozen slide "ways" on the
calipers or frozen slide pins will cause brake drag. Pushrod adjustment is a
another source of dragging brakes and thus excess heat. There have been
several really good posts on this topic lately with detailed descriptions on
how to isolate the problem. Check this group and alt.autos.honda.
Another source of heat that is often overlooked because it is not obvious is
pad composition. When I worked at a Ford (ugh!) garage as a service manager,
there was a problem with Torino station wagons where the composition of the
brake pad material allowed transfer of friction material to the surface of
the rotor and so you ended up with two high friction surfaces instead of one
and brake application generated twice as much heat. Not until the pads were
replaced with a new updated pad material and the rotors cleaned of old
residue and trued up did the problem of warped rotors disappear. If the pads
you are using are aftermarket, then ditch them. Ask the dealer if there is
Tech bulletin or service news item on this problem and go from there. If the
pads have an updated part number use those instead of the old number.
