Brake light stays on
Brake light stays on. Seems like the piston in the master cylinder isn't returning to it's fully extended position and lever will not depress the switch button enough to turn the light off. What may cause this? The bike is a Fat Bob 2013 with ABS.

Have you done any work to the bike, maybe something involving the hand brake lever? Sometimes people break the little switch up there and don't realize it (very hard to tell sometimes, then the switch isn't fully pushed in and never turns the brake light off. I would try unplugging both the front and rear switch connectors and then plugging in one at a time to see if either causes the light to come on, then you could isolate it to the correct switch.

The workshop had the front switch replaced this week but it did not help. The problem is that the lever isn't returning to it's fully extended position.
The bike is completely stock, just Stage 1. And it is also well taken care of. Always stays in garage night time and I usually don´t use it in rain.

Sounds like the master cylinder return spring is weak. That can be rectified by rebuilding it, you can do it yourself for about 20 bucks.

Is it possible to lubricate it so it will be able to move easier without rebuilding?

Technically yes, but it would require disassembly in order to do that, and at that point like I said, the rebuild kit is around $20...
