Brake light not working from back brake

[Wnuudiction]

Haven’t gotten into it yet, but just checking if anyone has had any issues that they have worked out. I see there is a connection under the motor which I’ll disconnect and spray electrical cleaner in. I don’t know if there is a pressure adjustment on these brembos. Figured I’d ask before I make more work for myself. Front brake works fine.
Thanks

Do you have the diagnostic app on a computer?

No I don’t.

No I don’t.

You will have to rely on more conventional diagnostic techniques. Diagnose the switch first. Does it complete the circuit when extended? If so, then your attention should move to the bulb socket.

You said connection under the motor...did you mean the brake pressure switch on the Brembo master cylinder? Also are your turn signals working?

The one to the sensor on the master cylinder. The front brake, turn signals work. The rear brake used to until a couple weeks ago.

Check the connection between the sensor and harness. It's a separate harness for the subframe. Since the turn signals are working sounds like a loose contact.
