Hello – with my Audi Q2 the brakes squeak when I drive backwards and tap the brake slightly. (e.g. when driving out of the garage, or park out. The noise is so terrible that you would like to stop immediately. The brake pads have been checked and the discs are also ok. Brake behaviour is quite normal. Vehicle is first registration 07/2020 Someone an idea what that can be? Thank you for your tips.
