SECTION: _3.5.1.1 Actuation_ PAGE NO._124_ PARAGRAPH NO._ _ MANUFACTURER'S REQUEST: Contractor is to provide electronic monitoring (specifically brake stroke) as part of the vehicle air disc braking on-board diagnostic system. The electronic brake monitoring System shall include both parking brake and service brake electronic monitoring utilizing a computer module with appropriate software, brake application pressure sensing via pressure transducer(s), associated cabling communicating the required electronic signals, and optical as well as mechanical sensing at the brake actuator / air disc caliper. The electronic brake monitoring system shall be designed ] [We propose to the MGM e-stroke brake monitoring system(as proposed in previous order). Although meeting the specification requested, this system does not specifically employ embedded optical and mechanical sensing at each wheel end which monitors operational conditions for air brake delivery and release, (as well as mechanical conditions inside the caliper that effect lining and pad clearance), and the proper mechanical functionality of air disc calipers at each wheel end position. We request your approval. METRO'S RESPONSE: APPROVED X DENIED APPROVED AS MODIFIED_ COMMENTS: APPROVED BY: DATE: Andrei Dragomir 10/20/2017 Project Manager
