1. Disc brakes get hot when in operation Therefore never touch the rotors im mediately after stopping and especially not after longer descents Ensure that you always have a spare pair of brake pads and a brake pad fit ting screw in your emergency set 7 4 Braking before in corners You risk a crash if you ride too fast into a corner It is also easy to crash if you only start braking once you have entered the corner For that reason you should always reduce your speed before you go into the corner Release the brakes as much as possible on entering the corner so that the tyres can maintain optimum grip in the corner ing Please visit www magura com to get the latest information on our prod gt 2 LS i s i The technology and our knowledge are constantly improving and expand ucts and additional useful tips s MAGURA 8 TRANSPORT OF THE If the brake pads have BICYCLE It is necessary to note the following points regarding the brake system when transporting your bicycle Never operate the lever blade if the wheels have been removed However if that has happened and the rotor can no longer be pushed between the brake pads then slowly push back the brake pistons with the transport de vice while the pads are mounted Do not use force If nec essary do this from various angles until the brake pistons slide back without needing to use excessive force It is essential to check that the
