More than likely your brake pads are worn down to the backing plate and need to be replaced.
They are equipped with a "telltale" warning that shrieks when the brakes are applied, with the brake pads are too low and need replacing.
Probably scoured or warped rotors.
Inspect the brake pads. They are probably worn out and need replacing.
When there are any issues with your brakes it is best to take your car in to a certified mechanic. Brakes can knock for several reasons, including the calipers, brake pads, and bearings.
this is usually the indicator that you need new brakes so dont worry just get them replaced problem solved
When the brake pads are worn the rivets will actually touch the brake rotor when the brakes are applied. The brakes should be changed immediately.
Most times, the squeaking and rubbing noises are caused by brake pad wear, but you say the brakes are fine. Otherwise, if by constant rotation speed you mean the squeaking/rubbing noise is present even when the brakes are not applied, you might want to get the wheel bearing inspected
sounds like you need pads cheap fix
depending on the year it might be a bad bearing, ball joint or spindle. have a mechanic check it out
Kinetic friction is the force that stops a train when the brakes are applied
Roaring, purring, grunting, snarling and hissing.
