Guys, I have a very big problem with my brakes, I bought new shimano mt200 brakes and installed everything normally, nothing bothers me, there are no problems with the brakes, the brakes work well, but the back one makes a loud screeching noise when I brake suddenly, and that annoys me, and it means that I clean everything and tried with alcohol and sandpaper and the same thing again, but until I brake slowly, it doesn't screech.
