Why does the Tacqua make a rattling noise when braking at startup?

[AubreyMarie]

Tacqua may make a rattling noise when braking at startup due to worn brake pads that need timely replacement. Brake pads are consumable parts that gradually wear thinner during vehicle use. When the friction layer is nearly depleted, an alarm device—the brake pad's limit iron piece—located at the edge of the pad will scrape against the brake disc, producing a sharp metallic friction sound as a warning to the driver to replace the brake pads. Below is an introduction to brake pedal operation: 1. Introduction to brake pedal operation: Brake pedal operation in vehicles is categorized into slow braking (predictive braking), emergency braking, combined braking, and intermittent braking. Generally, when performing slow or emergency braking, the clutch pedal should be fully depressed before the wheels lock or the vehicle stops to prevent engine stalling and facilitate speed adjustment. 2. Mastering braking timing and force: Typically, avoid stomping the brake pedal to lock the wheels immediately. Instead, first press the brake pedal with force adjusted based on need—quick and firm for higher speeds, gentle and steady for lower speeds—then adjust pressure according to the situation.
