B31 rear brake
« on: 11 November, 2018, 18:28:49 »

Hi Guys

I'm having trouble finding a home for the angled thing on the back brake lever set up, I purchased it from the parts listed (I have built this bike from bits) and it don't seem to fit anywhere, is it for M20/21 ? how should my back brake pivot look? I can't find anything in parts books and service sheets, so without finding a similar model I am stuck, it's a 1947 Rigid B31..Thanks for any help Lads

The lower part, 66 7033, is an M20 M21 part, not shown for the B series.

The shaft also looks M series, 66 7029. The B shaft 66 7035 looks different.

Below from 1947 parts book, first page the key, second the illustrations.

Which parts book are you using?
