Brake wear measurement system and method

A brake measurement system, comprising:

• a measurement mechanism, having a first end and a second end;
• a moveable member operatively coupled near the first end of the measurement mechanism, wherein the moveable member is at least one of a brake pressure plate or an actuator head which engages the brake pressure plate;
• an angular displacement sensor, operatively coupled to the measurement mechanism, wherein movement of the moveable member is converted by the measurement mechanism into an angular displacement measured by the angular displacement sensor;
• a mechanical calibration mechanism operatively coupled to the displacement sensor and capable of being detachably connected to the measurement mechanism;
• an interface bushing coupled to a scraper and operatively coupled to the displacement sensor, wherein the scraper is in contact with a measured surface of the measurement mechanism;
• a connector in electronic communication with the angular displacement sensor which communicates a displacement measured by the angular displacement sensor;
• and
• a visual indicator operatively coupled near the second end of the measurement mechanism, the visual indicator being visible outside a brake housing.
