Re: Steering problems and loose handbrake... ('73 XA)
Just adjust the drums up nice and even (should have some drag on it when turning by hand). First thing to do is loosen the handbrake cable completely off, then adjust your drums, then tighten the cable up. Another funky tip when handbrakes are uneven is to swap the drums (left to right). Don't ask me how, but it works, I've seen it with my own eyes on many occassions.
Oh yeah, also lubricate the whole handbrake actuating system (cable, linkages, the lot).
