Hi

That code (im guessing a P0171) is telling you the O2 sensor is registering too much air left over after combustion. That could be a possible faulty o2 sensor (can be checked with a DVOM) or you have a vacuum leak on that side of the engine.

As for the brakes, do a physical inspection. If the brake light is on, that could down to low brake fluid or a inbalance in the hydraulic system of the brake lines. Are the pads and rotors grinding?

So auto shops will offer a free brake inspection. Just an FYI.

Hope this helps.
