Also the trouble with manually adjusting is that if you have a lip on your drum (I bet there is) then you can't adjust the shoes as much as needed because the lip will stop you refitting the drum.
The adjusters do work when they are new but don't last past 50k or about 7 years. The answer is stick with manual adjusting or get new drums and self adjusting mechanism and be very sure you know how they go back together before dismmantling. And remember that how they are fitted now may not be factory correct as some ham fisted amatuer may have been in there before you.
Also if your front brakes aren't pulling evenly the rears will really struggle to keep you in a straight line. A small inconsistency on the front and the rears help but very much unevenness and you are in trouble.
I would suggest you go to your friendly garage and get it on the brake tester to check the stopping force of both front and rear on the brake pedal as well as the rear on the handbrake. That will give you a far clearer problem of where the issue lies.
Alternatively find a quiet road and test both footbrake and handbrake but that is far less sophisticated.
Finally to all those who say the cure is centralising the equaliser plate at the handbrake that is often (normally?) wrong and just a symptom of siezed self adjuster no longer working.

Author: MrBSI, Location: What's it to you? ? ?Posted: Tue Apr 28, 2015 12:49 pm ---- On the Toyota Tonero forklift with a Bendix brake drum setup, the auto adjustors for the brake shoes will only work if the truck is being driven backwards when you stamp on the brake pedal.
Ive yet to find one that actually ever works correctly & the same goes for all the other technicians I speak to that work on them
Luckily on these there is a rubber bung in the back plate so you can get at the adjustor easily - if you have the correct tool.

I intend to do what KandLBarrett suggested. I'll get the braking force tested at a garage and sort the brakes if needed, before I give it back to my wife to use for work. Better safe than sorry!
Cheers
