Abstract:
1. Disc brake for a heavy vehicle having an axle pressure between 6 and 14 tons, comprising a disc-shaped rotor ( 8 ) consisting of a cast iron alloy and having an active radius R and a caliper ( 30 ) supporting a brake lining ( 32 ) which is intended to be pressed against said rotor ( 8 ) during braking, in which said rotor ( 8 ) and brake lining ( 32 ) are arranged to absorb a brake power corresponding to a braking torque between 12 and 25 kNm and in which said brake lining ( 32 ) has a radial extent B, characterized in that a ratio B/R between the radial extent B of the lining ( 32 ) and the active radius R of the rotor ( 8 ) is less than 0.38 and thereby substantially limiting a number of band shaped wear modes.
