Hello. This can be caused by low brake pad lining or by low brake fluid. I would usually start by checking the brake fluid level. If the fluid level is low then it will cause this light to come on. If the fluid is low then the brakes need to be checked also as low brakes are the main reason why the brake fluid would be low.
