摘要： The invention relates to a method (600) for determining a braking torque (MB) on a braking system (100) for a rail vehicle. The braking system (100) associated with at least one wheel or at least one wheelset comprises at least one brake disc (102) for generating a braking force (FB) in response to at least one brake signal (340), at least one brake lining (104) interacting with the brake disc (102) and a brake caliper (106) connected to the brake lining (104) and a brake housing (108) and a securing bracket. Furthermore, the brake caliper (106) is mounted together with a brake housing (108) in at least one first bearing point (110) and a second bearing point (112), said second bearing point (112) being at a distance from the first bearing point (110) at a predefined bearing distance (A), a first sensor (116) for providing a first measuring signal and a second sensor (118) for providing a second measuring signal being arranged on the brake housing (108) or between said housing and the bracket (114). The first measuring signal and the second measuring signal each represent a force (F
1 , F
2 ), in particular a bearing force, or a variable derived therefrom. Said method (600) comprises a step of reading (610) the first measuring signal and the second measuring signal and a step of determining (620) a braking torque (M
B ) using a mounting dimension (X0), the bearing distance (A) as well as the first measuring signal and the second measuring signal, said mounting dimension (X
0 ) corresponding to the distance between a rotational axis (122) of the brake disc (102) and the first bearing point (110).
