Ross, I suspect that the brake drums on your car are warped. This
will result in you being unable to adjust the rear brakes correctly -
if you tighten them own so that the wheels turn, but catch at certain
points, the brakes will wear so that they turn freely within a few
miles. Each time you do this, the problem will get worse -- the heat
will warp the drums even more.
Otherwise if you set them so that the wheels turn freely, it will feel
as though the brakes are adjusted too far out. This will cause the
pumping required to make the brake pedal feel firm.
Find some new (or old but unwarped) brake drums.
Regards,
Simon
