2004-08 F150 dash brake warning light staying on. 

Perfect video. Tanks.

The small 821 next to the big one was my problem on my 2008 f150 but I still went in and touched up the soldering on all of the joints on that side of the circuit board and now everything works as it should

The top left white circle thing is your fuel gage, bottom one is for Volts,, as I'm sure you already know by now.

There is a much easier fix for this issue. The lack of voltage ( 5 volts ) going to the break fluid level sensor from the instrument cluster because of the circuit board connection. Just add 5 volts to the dark green/ yellow stripe wire using a 12 to 5 volt reducer. Wire is easily accessible at the instrument cluster left side connector.
