Hi,

I'm at a point where I'm finally assembling all the bits I've aquired over the years, however I seem to have acquired several front brake arms of various lengths !

They all fit the brake plate /cam; can someone advise the correct measurement, (end to end) to allow me to select the correct one for part 90-5547.

Thanks

Paul

Hi Paul

On my 1955 D1 the overall length of the front brake arm is 84mm.

Cheers.  Bruce.

Fit the longest one. 

My 1953 D1 had a short arm on it when I first got it, and I was advised to swap it for a D5 item that was 1/2” or so longer. The extra lever movement isn’t noticeable, but the additional braking force is. 

I’ll measure the one I have fitted for you, the original one is long gone.
