I have recently obtained the correct front brake plate for my 1940 deluxe M20
It needs some attention however to the brake mounting arm
It has been modified over the years and instead of having a bolt hole and slotted groove, it just has a single hole - also, the outer shape is changed due to additional metal being welded to it
Does anyone here have a brake plate that they could trace or draw around for me so that I can bring this to a local engineering company so that they can re-shape and reform for me
I think you have an earlier brake plate. These early brake plates with just a round hole also lack the possibility of adjusting the brake shoes as it doesn't have a slotted hole for the fulcrum pin.
I have altered one for my green bike but the non adjustable fulcrum pin makes it hard to get the brakes to work ok.
