Rear drum brake lever pivot problem

Postby kettle738 » Wed May 16, 2018 9:01 pm

My last R100 was a 1983 bike with a rear drum brake, I learned from that bike about the bush that should turn, but tends to seize in the frame lug and managed to fix it quite easily.

I now have another R100, this being a low mileage 1981 bike, identical in most respects to the previous one....looking at the rear brake pedal I can see that it is a little misaligned as if slightly twisted, the rear light switch is activated, but only just, with the adjustable bolt just clipping the edge of the switch button.

I haven't dismantled any of this yet, but at first glance it looks as though the tube (frame lug) that acts as the housing for the lever pivot is slightly bent......the lever is very vulnerable to a fall and the force will be passed into the pivot this a common problem......can the pivot be straightened and is it likely to cause me much grief doing so? :roll:

Any advice gratefully accepted......I'm sure I can't be the first to face this problem :pale:

Nine times out of ten it's simply a matter of the plate that the switch if mounted on bending and a judicious tap with a drift will bend it back to where it needs to be.
