I fitted these a couple of years ago and they are great, however after this winter period layup i rolled the trike out and ran it up, no problem, till i went to ride it into the garage. The rear disks were locked on. when i got the trike out i did pull the hand brake on quite hard as it got near my car.
There are no brake light on indicating a master cylinder problem so i think the handbrake mechanism adjusted itself when i pulled it on sharply. As yet i have not looked at it, i am going to somehow prise the brake caliper off the disc.
Has anyone come across this with rear disk brakes.
