Having reassembled the rear wheel on my Jubilee I was disappointed to find that the brake pedal is not returning very well. The brake shoes are new so there no great travel in the drum lever, that brake springs are new and there is no binding at the pedal or lever end; everything is free to move as it should. It feels like there is just not enough 'pull' from the brake springs to return the brake lever.
I have not seen the bike assembled so my question is should there be a pedal 'return' spring behind the brake lever to assist the brake drum springs?
There is a hole in the boss that holds the brake cam/brake lever where s spring might locate but that hole may be for lubrication.
If there is no additional brake spring I am at a loss to know what is wrong.

Ulrich,
Many thanks, you confirm that the hole is for lubricating the brake cam. Interestingly, the hole on the Jubilee does not look large enough to take a grease nipple and it is not threaded. I'll check the brake cam clearance and use a shim washer if required.

Hi Dennis,
There is no additional spring that I have ever seen. The brake shoe springs are pretty strong in themselves so really you just make sure the brake cam and the lever mounting are well lubricated. The brake lever in my experience never "positively springs" back but the brake should definitely release and the wheel turn freely. Maybe you are adjusting it up too tight? You really need to get a good run out and let the brake bed in before final adjusting.

Dennis ,
the hole in the boss is for a grease nipple, I mounted one but it screwed in too far so it blocked the brake cam! It worked with an extra copper whasher. Also because of a missing whasher between the brake plate and the drum the brake shoes and cams hit the rear wall of the brake drum. Check that .
