This is the shorter brake arm fitted to many Nortons with 7 inch front brakes. It measures 66mm from the centre of the cam to the centre of the pin. 
 
We also sell the longer version for the 8'' brakes. 
 
Laser cut in stainless steel to ensure the best possible fit on the cam, they can be fitted as supplied, or can be polished to give that mirror finish on a concours machine. 
 
This sale is for the brake arm only – cam spindle is for illustration only and is not included
