If your vehicle has a few years on it, you've no doubt had your tires rotated a few times. That means, of course, that a technician has loosened the lug nuts (which hold the wheels on) to remove the wheels and then put them back on. Many vehicles have lug bolts that go through the wheel into the wheel hub rather than bolts that are attached to the hub and poke out through the wheel. For our purposes, we’ll simply refer to both styles as “lug nuts”. Don't be surprised if your Service Advisor tells you it's time for several of those lug nuts to be replaced. Here's why. There are different styles of lug nuts. Many of them are constructed from two separate pieces. One is the main part that is steel, and the other is a chrome, aluminum, or stainless steel cap that fits on top and makes it look pretty. Time takes its toll on your lug nuts because they're exposed to the elements (salt, water, grime). The st ... read more

Disc brakes are called disc brakes because of the big metal disc – or rotor – that spins with the wheel. The brake pads rub against the rotor to slow the vehicle. In technical terms, the motion energy of the moving vehicle is transferred into heat energy by the brakes. The job of the rotor is to absorb that heat and dissipate it into the atmosphere. To do that effectively, the rotor needs a certain amount of mass (measured by the thickness of the rotor) and a good surface to mate with the brake pads. Let’s talk about those two things. First is the thickness. A new rotor is nice and thick. It can absorb a lot of heat and dissipate it effectively. Over time, the rotor will wear away slightly. If it wears away too much, there is not enough metal to take care of this heat transfer and the vehicle will not brake as well. In fact, each rotor is stamped with the minimum thickness the rotor must have. When the ... read more
