Rear Brake Conversion
This conversion is for any Rambler that has the dreaded Bendix Non-Servo Rear Brakes. These is one of the hardest brakes to rebuild parts are impossible to fine . Shoes can be replace if you can find a place that will reline you old shoes. In the pictures you will see there is no star wheel, this system uses a two piece gear to adjust the shoes. The springs are very hard to install and if you have the hub on forget it. When I worked in the Dealership everybody that had to work on this system lost money. The Donor car needs to be any AMC from 1967 up V8 or 6 Cylinder with ten inch brakes.
