  • Tipp
    Hint for breaking-in:
    New disc brake pads require a certain break-in period in order to provide the full brake power.
    The following procedure has proved oneself: drag braking on a downhill until the brake power noticeably increases. Then let the brake rotor cool out. Afterwards do 20 full stop brakings from a medium speed. Attention: the rotors get very hot, do not touch them!
