Low-speed brake vibration is primarily caused by wear and tear on the brake discs and friction pads. The specific reasons for low-speed brake shaking are as follows: 1. There may be metal debris, sand, or other foreign objects between the brake pads and brake discs, which create noise when rubbing against each other during braking. To address this issue, you can try firmly pressing the brakes in a safe area. As long as it doesn't affect normal braking performance, there's no need to worry. 2. Newly replaced or modified brake pads may initially have a harder material composition than the brake discs, making them more prone to noise. This situation also doesn't require concern, as the noise will gradually diminish with normal use over time. 3. If regular maintenance is neglected for an extended period, causing the brake system to malfunction, it may directly rub against the protective metal plates on the brake pads. This can produce particularly sharp metal friction sounds or even sparks, necessitating immediate replacement in such cases. 4. There are various reasons for low-speed gear vehicle occurrences, depending on the vehicle model and condition. First, let's rule out the semi-engaged clutch state in manual transmissions, which can be resolved by applying more throttle or promptly depressing the clutch pedal—this is a normal phenomenon. 5. Additionally, issues with the vehicle itself, such as excessive carbon buildup causing the low-speed engine to run unevenly and produce vibrations, or long-overdue spark plug replacements leading to excessive oil sludge, misfires, and abnormal ignition, can also result in shaking.
