The same problems the world over, dude! The self adjusters are probably FUBAR, I had a problem with adjuster springs rusting away to nothing. It made going to Toyota spare parts fun, no sample to take, reading the micro-fiche(no computer list for the 82 single cab) and saying, " I think that's the one, but order those,too, just in case...."
Disc brakes are high on my list... <img src="/forums/images/graemlins/smile.gif" alt="" />

Excuses are for losers.
