Can anyone tell me the spanner size for the small bolt which holds the front wheel cylinder to the back plate. The larger bolt seems to be a 1/2"AF but I can't seem to find anything to fit the smaller one that goes into the blind hole.
Many thanks

The larger bolt is 5/16BSF (1/4Whitworth spanner size) & the smaller bolt is 1/4BSF (3/16Whitworth spanner size)

There seems to be a variety - I know mine were 1/2" AF and not 1/4 whit, and I managed to get a little socket from a cheap mini socket set to fit the small ones - no idea what size now ! Trial and error.

Agreed - would have been BSF originally but with pattern cylinders could be anything now - you get allen screws from some of the suppliers now.
