Hi Matt.. first, your mailer isn't inserting carriage returns, so teh above is
one long line to me, meaning I need to include it all. Makes things messy.
Now on the CHevy, if both are wearing that fast, (and your wife isn't
mashing thepedal!) I would look at something that operates both calipers.
Possibly the master cylinder isn't returning all teh way back, so when
the brakes and fluid get hot the fluid can't return to the resevoir and
it puts pressure on the brakes. There's also a chance the proportioning
valve is getting wonky but I've never seen this actually happen. Have you
bled the system to remove what contaminants you can?
