Title: CW Front Brake Linkage
Post by: william Jonker on 15 Sep 2016 at 18:05
 Can anyone help with parts or complete pivot assembly that operates the front pulley block brake. A drawing or sketch that I might use to fabricate it ?

which parts exactly? :
 pivot levers
pivot bolts?
side plates for brake block?

see my post here :

https://www.douglasmotorcycles.net/index.php?topic=5677.msg20587;topicseen#msg20587

 was helped by a UK member on here who could supply the raw parts that he did as a special run.

see if he chimes in

 we determined that the front brake side platesfor friction block  were different  to the backbrake  side plates - pivot holes were spaced diffenrtly - cant remember if was closer (or wider)
