Brake Pads: The most common cause of grinding noises when braking is worn-out brake pads. When the brake pads wear down to a certain level, they can start to make a grinding or screeching noise.
Rotors: If the brake pads have been worn down to the point where they have made contact with the brake rotors, the rotors can become damaged and start to grind.
Brake Calipers: If the brake calipers are not properly lubricated or if the caliper pins are worn out, they can also start to make a grinding noise.
Wheel Bearings: In some cases, a grinding noise when braking can be caused by worn-out wheel bearings.
Solutions:
Replace Brake Pads: If the brake pads are worn down, they should be replaced as soon as possible.
Resurface or Replace Rotors: If the brake rotors have been damaged, they may need to be resurfaced or replaced.
Lubricate Brake Calipers: The brake calipers should be lubricated regularly to prevent them from making noise.
Replace Wheel Bearings: If the wheel bearings are worn out, they should be replaced as soon as possible.
