Title: rear brake pedal
Post by: RDfella on 22.06. 2020 18:39
Just received a brake pedal from a seller, listed as '60 A10. looks a bit like 42-7027 or 42-4347 (online pics look identical). Is it correct? Reason I ask is it's quite different from the one on my '58 A10. This lever is splined to fit crossshaft, has a built-in lever (presumably for brake light switch?)  but way more bend - ie it sits further away from primary case. Wondered if maybe it was A65. No matter either way, as it's for the project so a bit of heating & bending won't destroy any originality.

Can't quite tell from the photo but the small lever near the spindle mount looks like it is for a brake rod?

or could that small lever near the spindle be the actuator for the later brake switches that fit up under the tool box - super rockets at least.
a better pic of the side profile would help.

Apologies - added two pics to the post, but one seems to have evaporated before reaching the forum. I'll try again:
BTW, the arm doesn't look man enough to operate a brake rod. I certainly wouldn't want to use it for that. Also, the rod is splined to fit the crossover shaft, surely making it suitable to RH brake cable.

Looks to be of the splined cross-over rear brake shaft fit.  Small lever on top to operate brake switch.

Just to make sure, I went to look at the pedal on my Plungie. It has a spline to engage with a short shaft that has the brake rod clevis on it

The actual foot pedal appears to have been welded on. That makes me think it's from a later bike,

Early full width rear hub A65 type.

An extension bolts on, via the small hole, to actuate the brake light switch.

You can see it on this sketch from the A65 Instruction Manual dated November 1961.

Thanks for that - what got me wondering was the amount of offset - the brake pedal would be almost 3 inches outside of the primary case, when normally they run as close as possible. And yes, the pad is welded to the shaft.
