Brake Capability

Post  MrTweedy on Sat Jun 14, 2014 12:35 pm

Just been tinkering with the front brake on my Merlin 53 and I can't get any more adjustment out of it. As it is, if I stand next to the bike and push while pulling hard on the brake, it will move forward without too much effort, some but not much. Just wondering if this is normal for these old drum brakes or should there be more resistance than this?

Best regards

Should do better than that really. Tried relining or cam feet?

You could try the following, Raise the offending wheel off the ground, remove chain if at the rear.Slacken wheel spindle and spin the wheel, while it is moving apply brake hard, do this a few times then while still holding the brake lever on, tighten wheel spindle. You have now centralised the brake plate and perhaps improved the braking action. You should check the condition of the brake shoes and brake drum in any case it is an old machine. Keith.
