Hello,
Got a Mechanics special tundra a while back. I wound up completely rebuilding the front end, including new brakes, brake lines, calipers, rotors, ABS sensors, etc.
During the work I borrowed the rear diff so I had to pull the axles out.
I put everything back together, adjusted the brakes as best I could, filled with brake master cylinder with fresh fluid and bled the system.
But I have the brake light coming on.
So I have done the following:

  • Checked the Parking brake pedal switch (disconnected it).
  • Readjusted the rear brakes -the adjusters are seized, but I do have a little bit of drag on the drums.
  • bled the brakes (again). -I did install speed bleeders, which seem a touch short, but I can get them tightened down and they don't leak.
  • Adjusted the parking brake cable.
  • double checked fluid level in the brake MC reservoir.
  • Checked the connections on the MC Reservoir sensors/switches.
I am out of ideas, though the truck stops without any issues.
I do plan on using the truck to tow a flatbed so I want to make sure the brakes are 100% ready to go, and the brake light makes me nervous.

You'll likely need to do some electrical work to check why the brake light is on. It should just be 2 things, either the master cylinder level switch or the ebrake switch. Bypass each one at a time and see if you can find the source of the problem.
