Why does the X-Trail make abnormal noises when shifting to D gear and stepping on the brake?

[VanSabrina]

The reasons for abnormal noises when the X-Trail is shifted to D gear and the brake is applied are as follows: Severe brake pad wear: Abnormal braking noises at low speeds are likely due to severe brake pad wear. The warning indicator may emit sharp abnormal sounds to prompt replacement. Alternatively, the brake disc or brake drum may be excessively worn, and if too thin, could also produce abnormal noises. Another possibility is that the brake pads have just been replaced and are not properly fitted to the contact surface of the brake disc or drum, leading to point or line contact and resulting in abnormal noises. Engine aging: If the vehicle has been in use for a long time, the rubber of the engine mount cushions may have aged due to high-temperature fatigue, easily causing resonance. In severe cases, there may also be bumping or friction noises. Protective plate deformation: Deformation of the engine protective plate or improper installation can cause engine resonance. This situation is relatively common and easy to resolve.
