Brakes: Frequently Asked Questions
Brakes are one of the most important and complex parts in your vehicles. From pads and rotors to calipers and linings, brakes consist of many parts that need to be regularly changed in order to ensure proper stopping effect. Below is a list of frequently asked questions about brakes.

When should I change my brakes?

There is no general rule of thumb, as brake wear varies from driver to driver. Generally, you should have your brakes inspected at least once a year, but some manufacturers suggest a routine inspection at every oil change. Your pads should be more than 2/32 of an inch; however, if you hear grinding or feel pulsing, it may be time for a brake change. Also, if hydraulic brake fluid levels are low, this is also an indicator that brakes need changed.

Pads, rotors, calipers, and linings: What’s the difference?

When people say it is time for a brake change, they are usually referring to the pads. These come in contact with the rotors to create friction, and often wear down over time. Rotors may have to be replaced if they warp or rust. Calipers are activated by the brake pedal, and they squeeze the rotors and pads together. Finally, the lining is actually the surface of the pad that comes in contact with the surface of the rotor.

What is brake fluid and when should I change it?

Brakes are partially hydraulic systems, meaning they use (brake) fluid to activate systems. When you press the pedal, it manipulates the pressure and fluid movement to squeeze calipers, creating friction and bringing your car to a stop. You should check brake fluid at least twice a year. Generally it does not need changed or filled – if it is nearly empty, you may need new pads.

Regular brake maintenance can extend the life of your car and prevent accidents. Although nobody likes to spend money, changing your brakes can save you money in the long run. You should always have brakes inspected as often as possible, and pay attention to rust, pitting, and warping. Even if you don’t drive often, letting your car sit for a long period of time may require you to get new brakes.
