What could be causing this Brake Failure Alarm?
My 2013 ST-L often has a brake failure alarm. It is obvious the parking brake is not on as it rolls easily in neutral. If I turn it off and restart the alarm clears. I have the cowling removed from the RHS and the switch is definitely activated. I can close the switch manually and the light goes off on the dashboard.
Any ideas what could be causing this? Bad (intermittent) switch or something else?

I had that on my 2012 RTL and the brake fluid was just a tad bit low. Tech filled to top, cleared the code and didn't have any other issues.
They are a little touchy if they get just under full.

Not having your brakes service every 2 years can cause all kinds of problems.
The parking brake is an electric motor with cable attached to the rear caliper. Could be the battery is going or not great. - Nothing to do with the hydraulic brake system, so adding brake fluid does nothing for the parking brake.
If the brake fluid reservoir is very low then its either a leak or the brake pads are worn out. Adding a little brake fluid won't fix that.

Try resetting the Brake Failure
Make sure the key has been turned off for more than 30 seconds. Turn on the ignition key. Wait for the screen to finish booting up. You may not need to push the Mode switch but it won't hurt. Press the brake pedal hard enough to activate the low pressure switch. HARD. If you have good hearing it will be the 2nd click. While holding the brake pedal down. Turn the ignition key off and wait 30 seconds. Release the brake pedal. Then check if the code is cleared. Repeat as necessary.

Thanks guys, I'll top off the brake fluid. But it seems like it must be the micro switch located on the parking brake mechanism as this resets the error.

I topped off the brake fluid and tweaked the micro-switch lever. I'll see if it happens again.

Well, it happened again. After further reading I found that a Brake Failure alarm is different than a parking brake issue, that is a separate alarm, (Parking Brake Failure). The two brake fluid reservoirs are full, brake pads at about double the minimum required and the brake light switch is functioning properly. Also, the brakes feel like they are stopping fine.

The alarm clears upon re-starting the bike.

The sensor can fail. Maybe the float get stuck
