Brake system for a rail vehicle

A brake system for a rail vehicle (100), which brake system comprises a brake unit (200) configured to receive a brake command (cmdB) and response thereto execute a brake action, the brake unit (200) comprising:

• a rotatable member (110) being mechanically linked to at least one wheel (105) of the rail vehicle (100),
• first and second pressing members (211, 212) configured to move relative to the rotatable member (110) to execute the brake action,
• a brake actuator (120) configured to produce an electric brake-force signal (BF) in response to the brake command (cmdB),
• a gear assembly (220) arranged to operate mechanically on the first and second pressing members (211;
• 212), and
• an electric motor (230) configured to act on the gear assembly (220) in response to the electric brake-force signal (BF),
• wherein
• the brake actuator (120) comprises a processing unit (125) configured to produce the electric brake-force signal (BF) based on the brake command (cmdB), and
• the processing unit (125) is configured to produce the electric brake-force signal (BF) on the further basis of a force signal (F) reflecting the magnitude of a force applied by the first and second pressing members (211;
• 212) on the rotatable member (110).
