New pads require a bedding-in period, approximately 400 km, before they provide optimum friction. The slightly
reduced braking effect can be compensated by applying greater pressure on the brake pedal. Do not strain the brakes
too much during the pad bedding in procedure.
Ceramic brake disks improve braking efficiency comp ared to standard disks because of the following
characteristics: better deceleration/load ratio at pedal
better resistance to repeated braking with less wear of pads and disks
