A symptom of excessive brake disc run-out is a pulsating or vibration felt in the brake pedal when braking. This can occur due to uneven wear or warping of the brake discs, leading to inconsistent contact with the brake pads. Additionally, drivers may notice a squeaking or grinding noise during braking, indicating a potential issue with the braking system.
worn thin
With rear drum brake:-The brake drum may be out of round or may have a rust spot in it. -The brake drum may be cracked.With rear disc brake:-The brake disc may have extreme lateral runout or be mounted improperly. -The brake disc may be cracked. This would be dangerous-Combination of soft brake pads and a directional finish on the disc surface. A directional finish may go away with use and take the noise with it.Regardless of brake type:A brake disc or drum mounted to a bent hub flange or bent axle shaft can cause this noise.
A disc brake rotor with excessive run out is a warped rotor which causes a pulsation in the brake pedal when the brakes are applied. A certain amount of run out is acceptable.

The rotor is the disc in the disc brake system.
In case of cost..drum brake is better than disc brake.
Lateral Runout and Thickness Variation. I have this question on today's class too, I found it.
Converting a rim brake wheel to a disc brake system involves replacing the wheel hub with a disc brake-compatible hub, installing a disc brake rotor, and attaching a disc brake caliper to the frame or fork. This process may require specific tools and expertise, so it is recommended to consult a professional bike mechanic for assistance.
There are many purposes to using a disc brake. Disc brakes are mainly used in industrial drills because the disc brake stops the drill gently so it doesn't overheat.
Brake disc failure can be caused by several factors, including excessive heat from prolonged braking, which can lead to warping or cracking. Poor-quality materials or manufacturing defects may also contribute to premature wear or failure. Additionally, corrosion from road salts or moisture can weaken the disc, while improper installation or maintenance can exacerbate these issues. Regular inspections and adhering to manufacturer guidelines can help prevent brake disc failure.
The disc brake caliper is attached to the steering knuckle or spindle.
