Drum Brakes

OK---it's been a while, so bear with me...

I've noticed that the brake stays on this Montesa are solidly fastened to the bike on one end, and to the backing plate on the other.

I assume that precautions should be taken to be sure that the backing plate is aligned with the drum, but would it help to allow the backing plate to float a little so the shoes will be able to square themselves to the drum?

I have also noticed that the front stay is made of particularly soft stuff; maybe it has enough flex to allow the shoes to center.

Once the axle is tightened on a Cota, there is no way that the backing plate can move to allow the shoes to fit the drum better.

Like 99.9% of drum braked trials bikes, you should tighten the axle and the torque link with the brake shoes holding the backing plate in the correct position.

What I was thinking was: sometimes a brake plate just has a slot the fits onto a boss. This allows the whole plate to wiggle a bit so the plate will center when the brakes are applied.

I thought this could be accomplished with my bike by having the brake stay (or torque link) ride on shoulder bolts rather than cinching it rigidly on both ends.

HondaRS--I'm sorry...you lost me. But I am interested.

Could you send or post drawings or pics?
