Left rear wheel blocked briefly?

Hi folks, I had a very strange problem with my Tudor today.

Last weekend I drove a good 100km to a classic car meeting, everything was good there. Today I get the car out of the garage, I only want to drive about 10km, suddenly the left rear wheel blocked 3 times in a left turn ?! Once in the roundabout, even the stern broke slightly.

Then at home I jacked up the car and turned the wheel, and I was lucky that the problem just reappeared. When the wheel was turned forwards it blocked, when it was turned backwards it ran free. It felt like the handbrake lining was wedging on the brake drum, locking the wheel. (You can turn the wheel a little when you apply the handbrake until the handbrake pad is in contact with the stop. A few degrees.) I had this feeling here too. After that I dismantled the wheel and brake drum and checked, but no problem could be seen! Everything went smoothly, the brake releases properly ... I have no idea why that was. The wheel hub was also freely moving and didn't hit anything.

I have to say that I recently overhauled the handbrake. New handbrake shafts including the bearing + bearing sleeve were used. The small handbrake lever in the drum has been retrofitted with a hole and a grease nipple so that it can be lubricated. The handbrake strap has been completely refurbished and given new pads. These were sanded perfectly round ... New return springs were installed. Actually everything is great! The small bolts were also installed with the flat side facing out ... So nothing can get stuck.

At the moment it's all a mystery to me. Does anyone have any idea what else could be the problem? I wouldn't want the wheel to lock while driving. Then the damage might be greater.

I hope that after the Google Translator there is still something useful to read from the text.
 
If the emergency brake lever spring is broken it is possible to experience this situation. Worth checking the backing plate area to see if that is the case.
 
First of all, thanks for all the feedback.

I would like to rule out differential. I turned the wheel hub without the wheel and brake drum, so everything went smoothly and freely.

I also chamfered the new brake pads at the ends. Everything fits.

No traces of sanding can be seen on the carrier plate. That would be noticeable as these were repainted. You can see notches on the brake drum, but I think that these are much older. There are no fresh traces to be seen.

The handbrake lever return spring is new. I even had to buy two sets because the first two broke during the cumbersome assembly. The now installed are in very good condition.
 
Check the wheel where it touches the drum. I had a welded wheel and when I torqued the lug nuts, it would warp the drum and cause a drag. there was a small proud bit of weld on the surface that would not let the wheel sit flat on the drum. Just a thought.
 
sounds like maybe you have some teeth come off the ring and pinion
drain the oil and see if you have any pieces

The same thing happened to my 29 Tudor when I first bought it. It was caused by the parking brake band binding in the forward direction, but not in reverse. After I redid the brakes and fixed missing rivets, etc. all was fine. Also make sure the drum brake contact surface is smooth and dry.
 
Thanks Jackson, I'll check today.

As I said before, I would like to exclude the differential with tooth loss. This damage would make extremely lingering noises when driving, both forwards and backwards.

@ Tom, I think that coincides with my experience. What just amazes me is that it occurs AFTER the brake repair. I thought I had done a clean and tidy job.

I have to admit, I only drove about 100-200km after the repair. The new pads will probably not adapt to the old brake drum that quickly.
