i think the assembly is correct because it works perfectly when the fastening bolt is on but loose.
if i overtightened the bolt, which i too think i may have done, what would have been likely damaged that would cause this malfunction?
this is happening to me repeatedly on lots of these shimano early 90's center pull brakes and every time i start to tighten them to a good torque they seize or the return gets heavily dampened. maybe the washers are old and junk?
what part of the brake is the bushing? and how would you make it thinner?
one of the brakes is the shimano br m650. all others are very similar.
