How thick are new brake shoes?

New brake shoes typically have a thickness of around 1/2 inch to 3/4 inch (12 to 19 mm), depending on the vehicle and the specific type of brake shoe. The thickness can vary based on the manufacturer and the intended application, such as for standard passenger vehicles versus heavy-duty trucks. It's essential to check the specifications provided by the manufacturer for precise measurements. Regular inspection and maintenance are crucial, as worn brake shoes can significantly affect braking performance.
