Pulled my 1974 R90/6 out of the shed today. Started right up and everything seemed okay except my brake failure light is on. Rode through my subdivision for about three miles, front and rear brakes both work??? I tried doing a search under airheads for "brake failure light" and got a Brazilian hits on every variety, year, and model of BMW bike before posting here. I would love to hear thoguhts/ideas/suggestions from those more technically proficient than me on what could be causing this.
Thanks in Advance,
