Why is my brake fluid empty with no leaks on the ground?
When the brake fluid reservoir is empty but there are no puddles on your driveway, the fluid is likely leaking internally—often into the brake booster—or dropping due to heavily worn brake pads. This sudden fluid loss compromises braking safety and leaves drivers worried about expensive repairs they cannot afford.
