Brake rotors wear because during use, brake pads are pushed against them while the rotors are turning. It's the friction between the moving part and the staationary part that slows the vehicle down. Pads wear too, usually quicker. Brake rotors wear due to use, they are considered a service item.
Brake rotors wear just as brake pads do and when they wear down beyond minimum specs they become unsafe. Good brakes are a # 1 priority.
Bad rotors
As long as your rotors are not warped, or you have not let the brake pads wear to the point they defaced the rotors, there is no need to change them. Just install new brake pads. Rotors can last the life of the car.
You need to check the following brake rotors for warping Pads for uneven wear wheel bearings for wear steering control arms and ball joints may be worn out
Wearever brake pads are sold at Parts America and Advance Auto Parts. They are made by Wagner, hope this helps. I'm not sure that they are made by Wagner. Foster makes the Wearever rotors. But Wagner is owned by Federal Mogul and I'm pretty sure they are not the manufacturer of wearever pads.
Brake rotors are subject to a lot of heat and wear. After a period of time, they warp and have to be "turned". turning the rotors actually makes them thinner so they won't last as long as they did. Everytime they are turned, the thinner they get. There is a point where they are too thin to safely use. That point is stamped on the rotors and it is illegal for someone to turn past them that point. Rotors are not expensive and your brakes are the most important part of your car. I wouldn't skimp on my brakes.
usually it will to the brake pads wear a little or it could be your rotors
To stop bicycle disc brakes from squeaking, try cleaning the rotors and brake pads with rubbing alcohol or a specific disc brake cleaner. Also, check for any contamination or wear on the brake pads and rotors, and adjust the brake calipers if needed. If the issue persists, consider replacing the brake pads or rotors.
Rotating rotors can improve a vehicle's performance by enhancing braking efficiency and reducing wear on brake pads.
Brakes shudder due to uneven wear or warping of brake rotors. This can be resolved by resurfacing or replacing the rotors, and ensuring proper installation and maintenance of the brake system.
You either have a bad brake caliper or the brake hose is bad.
