Fred,
The OBC message is triggered by one of the two brake wear sensors. My 
guess is that either your front driver or rear passenger wheel sensor is 
worn through, unplugged or otherwise damaged. Inspect and replace the 
sensors and the message will go away. 
There is nothing to reset. The sensor is a simple wire with a plastic plug 
embedding it into the inboard brake pads on the corresponding front/rear 
wheels. When the pad wears, the wire is worn though as well interrupting 
the flow of current and triggering the 'replace brake pads' OBC warning. 
Primitive, but effective.
