What causes the squeaking sound when braking a cold Nissan Teana?

The reasons for the squeaking sound when braking a cold Nissan Teana are: 1. Abnormal noise from the car's brake vacuum booster, which does not affect driving safety. If the noise is too loud, the brake vacuum booster needs to be replaced; 2. Issues with the alternator belt connection. Mainly, the belt is harder when cold, and the surfaces of the brake disc and brake pads also change, causing noise when starting. The noise usually disappears after the car warms up. The Nissan Teana is a mid-size car launched by Dongfeng Nissan, with dimensions of 4901mm in length, 1850mm in width, and 1450mm in height, and a wheelbase of 2825mm. It is equipped with a 2.0L naturally aspirated engine or a 2.0T turbocharged engine, paired with a CVT continuously variable transmission or a CVT continuously variable transmission (simulating 8 gears).
As a long-time Nissan Teana owner, I often encounter squeaky brakes during cold starts, especially on damp autumn/winter mornings. This primarily happens because moisture or slight rust accumulates on the brake discs and pads overnight. The initial friction when braking causes that annoying sound, which typically disappears after a few minutes of driving as the brakes warm up. While this is quite common and not an immediate cause for alarm, it shouldn't be completely ignored either. Last year, my car squeaked continuously for two weeks, and it turned out the brake pads were nearly worn out and needed replacement - delaying this could have affected braking performance. Now whenever I hear the noise, I first test-drive briefly to see if it's temporary; if persistent, I immediately visit the dealership for inspection. Remember to rinse wheel inner surfaces during regular car washes to minimize this issue. The Teana is generally reliable, but addressing minor issues promptly ensures peace of mind.
