Replacement pads for the Magura MT Series 4-piston brakes. The Magura MT Performance Type 9.1 brake pad features a softer organic compound to help increase modulation, while remaining extremely quiet. 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 stops braking from a medium speed. Attention: the rotors get very hot, do not touch them!
