Abstract
Methods and apparatus to sense brake pad wear are disclosed. An example apparatus includes at least one memory device and at least one processor to execute instructions to, in response to an anti-lock braking system event, determine a volume of brake fluid in a brake piston chamber based on a flow rate of the brake fluid and a pressure within the brake piston chamber, and determine at least one of a thickness of a brake pad or a wear of the brake pad based on the volume of the brake fluid in the brake piston chamber and a volume of the brake piston chamber.
