Brake light on

[BlueBroncoATX]

I have a 2021 Big Bend Bronco with 45k miles and after a few minutes of driving, the Brake light will come on. Thankfully, car is driving fine. What do I need to do to fix so I can get car inspected.

I'll go on the limb here......maybe take the wheels off and check the brake pads? Better yet....order the set of front and rear pads now (so you don't have to take the wheels off twice), then take the wheels off, and replace them. Before you do that, check the brake fluid level (I bet it's low). Not because it's leaking, but the brake pads wear is replaced by the fluid volume. Adding fluid won't help you. Yeah,.........pads are gone after 45K miles.

Bring it to someone that can diagnose why the brake light is on is probably your best bet.

It's impossible to diagnose over the internet why your brake light is on.

You'll need to see what code is set, it could be any number of things. Likely it's telling you your pads are getting low, especially if you do a lot of city-type driving. If you do more rural/highway driving, you might have a different issue.

If you aren't mechanically inclined, I'd say a visit to a repair shop is in your future. If you are, well, it can't hurt to put a new set of pads on it, but be ready to have to go buy new calipers too.

Assuming it is not just worn brake pads, I recently had the brake light come on and took it to the dealership and it was the vacuum line. “trouble code (DTC) P050F…This may be due to contamination in a brake booster vacuum line. To correct this condition, replace the vehicle's vacuum hose (MB3Z-2420-A).”

If you do not have a code reader, local auto parts stores will typically scan your vehicle for free. That will at least give you the error code to assist with further troubleshooting.
