Front Discs; Wear; Removal - Triumph Rocket III Classic Service Manual

It is dangerous to operate the motorcycle with defective
brakes and you must have your authorised Triumph
dealer take remedial action before you attempt to ride
the motorcycle again. Failure to take remedial action
may reduce braking efficiency leading to loss of
motorcycle control and an accident.
