It is important to have working brake lights on a vehicle. If the brake lights are not working a person should first check the fuse, bulbs and at last the wiring.
Check the fuse, check the bulbs and check the brake light switch, in that order.

Check the bulbs they are double filamented -smaller for brake lights larger for tailights Check the fuse Check the stop light switch usually located at the upper end of the brake pedal under dash area
Just a suggestion, check your trailer lights harness for corrosion. They were taking the dash lights down in my chevy.
The brake lights and the tail lights are separate circuits. Check the brake light fuse, then check the brake light bulbs, then check the brake light switch.
The sensor states "check brake lights and brake linings" is this something I can do or must it go to the shop?
check the fuse, brake lights have their own, & check the brake switch at the top of the brake pedal
you do not adjust the brake lights check the bulbs or check switch top of brake pedal.
