In Reply to: 9N parking brake posted by Ron on November 23, 2022 at 19:58:10:
Red Rock Manufacturing in Pella, Iowa, makes reproduction parking brakes that will work on your 9N. Go to the LINKS section on this website and click on the Red Rock link. It will take you to their webpage with details about several brake products. I have a set of the FarMech brakes on my 1949 8N. They work very well. Good luck.
