TR2/3/3A Rear brake adjustments

Thanks for replies but I think I wasn't clear.I am not asking about the brake shoe adjustment with the adjuster,but the setting of the 2 screws and locknuts in each backing plate that have felt tips and screw in to hit the shoe web.These are in place of the typical retainer springs that these later brakes don't have.
Thanks

Tom is asking about how to adjust the threaded support posts, item 60 here
While I think Geo & John are talking about the main adjustment, item 50.
It seems odd that this was never documented, but I've never found where it was. What I did to adjust the posts was to remove the drums and adjust until the shoes were parallel to each other. I don't think there should be any clearance (the shoes still rest on the posts even when the brakes are applied); but I'm not convinced that applying the handbrake will necessarily move them out all the way. But I don't think that adjustment is critical at all, so it wouldn't hurt to try your method (with no clearance).
PS, the posts were only used on a fairly small range of cars, TS15332 through approx TS56376 according to the SPC. My last two TRs didn't have them, but back in the 70s I had TS42xxx which did. TS39781 should have had them, but someone had replaced them with 9" brakes before I got the car.
