Hold in place with the leg shields in place to check clearance.
A couple of decant jubilee clips around the bracket to secure.
On with the brake peddle return spring.
Connect the inner cable to the rear clamp and tighten.
Adjust cable tension until the rear brake shoes are nearly rubbing the drum.
Brake pedal sitting up right and operates the brake light switch as soon as the pedal is depressed.
