Default Brake light issue

Ok so my running lights work(when I turn on my headlights they turn on,they are the same bulb as the brake lights) but whenever I press my brakes they don’t get brighter . When I use my blinker they do and my hazards so the bulbs are fine but I can’t figure out why they just stoped working .is there a fuse or a ground I can check (2007 gt)I

Check fuse #15 in the SJB (smart junction box). That's in the passenger side kick panel. Also check fuse #63 in the BEC (bussed electrical center). That's in the engine compartment passenger side. Also check your stop lamp switch behind the brake pedal. Good luck!
