Fingers: If the width of a human finger is 2.2 cm (7â8 in), then a million fingers lined up would cover a distance of 22 km (14 mi). If a person walks at a speed of 4 km/h (2.5 mph), it would take them approximately five and a half hours to reach the end of the fingers.
The rotors on a vehicle can last anywhere from 30,000 to 70,000 miles and sometimes more. A licensed mechanic, such as one from YourMechanic, can evaluate the rotors and advise you on their status; they may not need to be changed as often as the brake pads. Like brake pads, they should be replaced in pairs.
Brake pads are not used in cars with drum brakes. It depends on the driver how long brake pads will last. A gentle driver can expect at least 25,000 miles on a set of front brakes. A vigorous driver may only get 15,000 miles. There are many types of brake pads; OEM, sport, heavy duty, and racing. The harder you drive, the faster the brake pads will wear out.
