My bike was recently tuned however it developed an irritating screech and lack of braking power, so we decided to change the disks and fix the problem. Changing the disks is vary easy all it requires is a torks T25 screwdriver, and preferably a torque wrench. If you don't have a torque wrench don't worry unless you are racing, screw tight will do.
Step 1: Tools and Materials
This is an easy project that takes about 30min the only tools needed are:
torque t25 screwdriver
torque wrench (optional) needs to go to 40-60in lbs
