Time to setup the disc brake
caliper bracket. The distance of the caliper to the disc is
important when setting up this bracket, however, the side to side
location is easily adjusted by sliding the disc on the axle.
The brake setup is very important. At 30mph, you want to be
able to stop quickly if needed. You will not stop on a dime
with this mechanical disc brake. A hydraulic disc brake is the
way to go. We would also recommend Azusa's band brake over
this mechanical disc brake (Part#
2251-13 & 2541).
