Vespa P125 Motor Rebuild Part 3

Removing the Rear Brakes

When you get the rear hub off, inspect the rear brake shoes, and the inside of the rear hub.

On this motor, the whole thing is a mess. There is brake dust mixed with grime on the brake shoes, and rust on the inside of the brake drum. We'll have to replace the brake shoes, and thoroughly clean the brake backing plate and the inside of the rear hub.

To remove the brake shoes, first, remove the small spring clips at the on the brake pivot pins. Be careful, and wear eye protection, because these clips tend to go flying when they are removed. I sometimes cover them with a rag while I am removing them so I don't lose them if they fly off the pivot pin.

With the spring clips off, you can now remove the brake shoes. Use two flat head screwdrivers for this job. Place one between the flat brake actuator and the top brake shoe. Use the screwdriver as a lever to push the shoe up and out of the actuator. Then use the other screwdriver to push the shoe off the pivot pin. Push the brake off the motor with both of the screwdrivers at the same time.

With the top shoe off, the bottom brake shoe simply slides off the bottom pivot pin.

The brake backing plate on this scooter is obviously very dirty. Even when they are not this dirty, I always clean the whole area, as well as the inside of the rear hub with brake cleaner. Having a clean brake drum area is essential to having good working brakes.
