Either the piston isn't retracting as it should, ir the whole caliper is failing to move as it should, causing the pad to drag and wear both pad and rotor.
The rotor takes the spark generated by the ignition coil and distributes it to each spark plug wire as it rotates on a shaft inside the distributor cap. It is subject to constant spinning and voltages that will wear it out in time. A bad distributor could cause premature wear.
Yes, brake pads touching the rotor can cause damage to the braking system by creating excessive heat, wear on the pads and rotor, and potentially leading to brake failure.
To wear....
The bearings inside a motor are typically located at both ends of the rotor shaft. They support the rotor, allowing it to spin smoothly while minimizing friction and wear. Depending on the motor design, there may be additional bearings or bushings within the motor to provide further stability and support for the rotor. Proper lubrication of these bearings is essential for efficient motor operation and longevity.
Normal wear on the bearings inside.
A bad rotor would not necessarily cause a bad vibration as it would most likely create a noise and wear your break pads down unevenly. It could be as simple as an unbalanced tire or a warped rim. Also if your tires are choppy then a vibration can become noticeable. Also a bad bearing or axle could cause vibration (however, it would be noticeable at a lower speed).
First I would have the rear rotors removed to inspect the emergency brake shoe's and rotor for wear. Sometimes people are known to drive with the emergency brake engaged which will wear the shoe and rotor. If they are still within specs, there is an adjustment on the shoe's
Common signs and symptoms of rotor wear in a vehicle's braking system include vibrations or pulsations when braking, squeaking or grinding noises, longer stopping distances, and uneven wear on the brake pads. It is important to address rotor wear promptly to ensure safe driving conditions.
Yes, a rotor can get bent by hitting a curb, especially if the impact is strong enough. When a vehicle strikes a curb, the sudden force can cause misalignment or deformation of various components, including the brake rotor. This may lead to issues such as vibration while braking or uneven wear on brake pads. It's advisable to have the rotor and related components inspected after such an impact.
Your brake caliper may be rubbing on the rotor due to misalignment or wear and tear on the brake components. This can cause friction and lead to braking issues. It is important to have a professional inspect and repair the brake system to ensure safe driving.
You need to have a 4 wheel alignment.
Poor tire alignment will cause wearing on the inside edges of rear and even front tires.
