Yeah, of coure I released the brake... but particularly when it's cold, the panel indicator light stays on for 30 minutes or so, seemingly until it gets nice and warm inside the cab. Likely to be the sensor out of adjustment? How do I remove panels to access it?
My parking brake light stays illuminated also. Just started this morning. Nothing out of the ordinary between last night and this morning. Any idea on a fix? My truck is still under warranty, but if I can jiggle a wire/clean out a switch - I'd rather do that.
I am the original poster. Although I called it the "parking brake light", technically it's just the "brake indicator panel light" (but not ABS light).
Reading the manual (gasp!) gave no indication (pun intended..), but I did eventual find a post on-line, as suggested in a response above, that it also indicates low brake fluid. On inspecting the resevoir, it was low, and when filled a small white plastic float could be seen rising, almost certainly the contact with the sensor embedded in the filler cap. Problem solved (although low fluid, without any leaks, may well suggest I need to have brake pads & rotors inspected for wear!).
