Confirmation your brakes, before driving your Vespa.
The brakes on your Vespa are one of the most important safety components on your scooter. You must keep them in perfect working order, at all times, if you intend to operate your Vespa scooter on the road. Rear brakes are often more susceptible to damage or corrosion, as a result of their proximity to the exhaust and the oil drain plug. Only perform this task if you have a functional respirator that is rated for asbestos. Factory-installed brakes on Vespa scooters contain asbestos, which is poisonous when breathed.
Instructions
1. Raise the Vespa off the ground ,with the jack, and lower your centerstand, to support the scooter.
2. Pry the hub dust cover off, using the pliers. Locate the castellated nut, found under the cover. The nut is grooved, and it holds the split cotter pin. Pull the pin out of the nut, with the pliers.
Push the shoe upward from the cam, and insert a second flat-head screwdriver, between the shoe and the cotter pin, on the pivot point. Push both sides, evenly, until the shoe comes free.7. Pull the old brake out, and put on your gloves.
5. Slide the hub and the wheel straight towards you, to remove them. Avoid spilling any oil, as it will damage the brakes.
6. Pry the two retaining clips off the brake pivots, and push down on the rear brake pedal to pivot the brake actuator. Insert a flat-head screwdriver, between the shoe and the cam, on the marked pivot point.3. Remove the castellated nut from the axle, using a ratchet and 22-mm driver. If you are encountering any difficulty, hit the end of the ratchet with a mallet, to give it more force.4. Slide the washer and the lock nut out of the hub, and set them aside.
Soak the rags in the brake cleaner; look for any traces of brake dust, and wipe it with the rags. Dispose of the rags in a garbage bag. Seal the bag to the best of your ability.
8. Position the spring into the new brake shoe. Clip the new brake shoe and the brake cam, and push the shoe and cam back on the brake pivots, to fold the shoe and cam to hook them under the second clip.
9. Replace the cover along with the washer and the lock nut to their original positions on the axle. Screw the castellated nut back on with the torque wrench, torque the nut to between 54.3 and 65.1 ft-lbs.
10. Insert the split pin into the castellated nut, and fold it over the nut.
