The brake pads or brake shoes are worn and rubbing against the rotor or drum, Disc brakes use brake pads and brake drums use brake shoes. Need to get them replaced before they cause too much damage or you will wind up with repairs or replacement of the rotors or drums also.
A grinding noise when braking can occur when the brake pads are going bad. You are hearing the brake grinding on the metal discs.
Check the brake pads on that wheel, it sounds like you have metal on metal if the grinding is only when you are stoping or right after you release the brake and start rolling
You possibly have warped brake rotors on the front. Or Bad Wheel Bearings.
Pads or shoes worn out. Take it to a brake place.
Common signs of wear and tear on a bicycle brake line include fraying or kinking of the cable, reduced braking performance, squeaking or grinding noises when braking, and difficulty in applying consistent pressure to the brake lever.
Warped rotor and worn out brake pads.
The grinding noise is the brakes pads proably the noise is in the front. The front brake pads are easy to replace and is a do it yourself sort of thing. My guess is your brake light is coming on because of this condition. I assume your brake light has been coming on for a little while now.
Some common brake noises that can indicate issues with a vehicle's braking system include squealing, grinding, and clicking sounds. Squealing noises may indicate worn brake pads, while grinding noises could signal metal-on-metal contact and the need for immediate attention. Clicking noises may suggest a problem with the brake calipers or hardware. It is important to address any unusual brake noises promptly to ensure the safety and proper functioning of the vehicle's braking system.
Brake linings worn? Wheel bearing?
Signs of a worn brake rotor include vibrations or pulsations when braking, squealing or grinding noises, and uneven wear on the rotor surface. A brake rotor should be replaced if it is too thin, has deep grooves or scoring, or if it is warped and causing braking issues. It is recommended to replace a worn brake rotor as soon as these signs are noticed to ensure safe braking performance.
It depends on where the grinding noise is coming from. Most of the time the grinding is coming from the brakes and the brake pads need to be replaced. If they've been grinding for a while, the rotors will need to be resurfaced or replaced. Other possibilities for grinding are worn axle bearings, or a problem with the clutch. If the clutch goes out, there will be a grinding noise when you try to shift gears.
Common signs of a bent brake rotor include vibrations or pulsations while braking, squealing or grinding noises, and uneven wear on the brake pads. A bent brake rotor can affect the performance of a vehicle by causing uneven braking, reduced braking efficiency, and potentially dangerous handling issues. It is important to address this issue promptly to ensure the safety and proper functioning of the vehicle.
