What do you think, what noises indicate problems in the brake system of a car?

✔️ The whistle of new pads, which lasts more than a week, speaks of their marriage.
Contact the service station for a groove or replacement service;

✔️If the old pads creak when braking, they are worn out.
You need to change either them or the brake discs;

✔️Hits from behind.
Difficult to diagnose, but usually it's the rear brake drums;

Either cheap brake pads or a brake pad wear indicator has hit the brake disc;

✔️ Knocking or screeching.
If the car has been parked on the street for a long time, this may be caused by rusty brake discs;

✔️ Scraping sound.
Perhaps a stone has fallen on the brake pad or caliper.
