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.
Using common sense you should examine the title to see if the odometer reading shows what you would expect. In most cases drivers can expect to put between 10,000 and 15,000 miles on a vehicle in a given year. A car that is 10 years old should have roughly 100,000 to 150,000 miles on it. Buyers can check brakes and tires on vehicles with less than 20,000 miles on them. Excessive wear should be a sign that perhaps the odometer is incorrect.
