And finally, I started working on the rear brakes. This brake hub sort of thing will attach to the left side of the rear wheel. I took the rotor and this rotor mounting plate (black one with holes) from an electric scooter, which obviously is the side the brake rotor will attach to. The washer and black plate will be connected by a 1″ section of pipe welded between them. Then I’ll need to mount the caliper to the left side of the rear frame.
