TBH I just keep forgetting to have a look. I've been at this handbrake thing for best part of 20 years and I don't think I've ever actually got around to simply looking to see if it could be done. Pretty dumb.
I took my assy all to bits both sides. Luckily I had oxy acetylene. The clevis pins inside the drum had rusted solid. Hardly any wear on the shoes (original 165 K miles) and only witness marks on the dog bones.What a nightmare getting it back together. By the time I had to assemble the second side I had worked out how to do it.
Assembling handbrake components:-
1. Put the front shoe (with lever) on first. First attach and let the bottom spring hang down then secure the shoe to the backplate with spring and clip.
2. Put cable/lever clevis pin in and press the clip together.
3. Secure hanging down spring to rear shoe and position shoe in place with fully closed adjuster. Hold in position.
4. Put bungy cord around the shoes to retain them in a circle and in their working positions.
5. Secure rear shoe to backplate with spring and clip.
6. Prize open the tops of the shoes and fit the dog bone in with it's spring next to the first shoe.
7. Fit the top springs. The stronger one goes on first and just above the dog bone spring. Fit the weaker of the two springs to the other shoe.
8. Fit the front shoe little spring.
9. Take up the play by pulling on the lever (attached later to the main cable) then undo the screw till it touches the backplate then loosen one turn. Do up lock nut
10. Attach the main cable. (This may be tight if the handbrake end is over adjusted, still proceed though).
11. Attach the two lever return springs to the backplate.
12. Adjust the nut on the cable/hand brake lever end until the adjusters just lift off the back plates then undo the nut one/two turns to let the main cables slacken slightly.
13. The shoes are still in their fully backed off position. Move the front of the adjuster wheel upwards on both sides ( drivers side left hand thread to achieve this) until the wheel stops and the brakes are locked on. Slacken off 6 notches.
I think that's it but corrections welcome. May help someone who has never worked on drum brakes before.
