My brake warning light came on this morning driving to work. I checked the parking brake (disengaged) and the brake fluid was full. Called the Mazda dealership they said could be my brake pads starting to wear. Anyone know if this is true?

 

It would help to know how many miles are on it and how you are driving in respect to the brakes.

Also it is pretty easy to check the brake pads.

 

Check your brake lights. Get a code check.
