Abstract: Pressure in a brake master cylinder is sensed. An optical transducer is affixed to a master cylinder housing. A pressure signal is generated by the optical transducer in response to hydraulic pressure in the master cylinder. A vehicle including a system for sensing pressure in a master cylinder is provided. A brake master cylinder having an access point machined into the master cylinder housing to access a hydraulic chamber is provided. An optical pressure transducer is also provided. A transducer mount assembly affixing the transducer to the master cylinder at the access point and a controller operably coupled to the optical pressure transducer are provided.
