The lifespan of brake pads in heavy off-road machinery typically ranges from 2,000 to 5,000 miles, while the lifespan for light-duty brake pads usually falls between 3,000 to 6,000 miles. Regardless of the brake pad material, they will eventually wear out. Worn or faulty brake pads can lead to braking failure, compromising the driver's safety. Therefore, it's crucial to promptly detect and replace worn brake pads to ensure safe operation.
