Before changing the rear brake rotor/disc, ensure you safety support and raise the vehicle. Now, come out the three wheel mounting nuts and take out the tire and wheel. After that, unscrew the bolt that holds the cable routing bracket to the axle. After that, remove the two bolts connecting the disc
Brake Caliper and adapter bracket to the axle. Remove the disc brake and adapter bracket as an unit from the axle and rotor, then use wire or a bungee cord to hang it someplace safe to prevent touching or overextending the brake line. Take out the last retaining clip and glide the brake rotor away from the hub and bearing once more.
