What are the precautions after replacing brake pads?

Here are the precautions to take after replacing brake pads: 1. Observation: The thickness of a new brake pad (excluding the steel backing plate) is generally around 10mm. When the visible thickness of the brake pad is reduced to about 1/3 of its original thickness (approximately 3mm), the owner should increase the frequency of self-inspection and be prepared to replace them. Typically, when the thickness is less than about 1mm, immediate replacement is required. Each brake pad has a raised indicator on both sides, with a thickness of about 2-3mm, which is the minimum replacement limit for the brake disc. If the brake pad thickness is level with this indicator, experienced drivers advise replacing them immediately. 2. Listen for sounds: If a metallic scraping sound (like iron rubbing against iron) is heard when lightly applying the brakes, it is recommended to replace the brake pads immediately. This indicates that the limit indicators on both sides of the brake pads are directly rubbing against the brake disc, showing that the pads have exceeded their limit. In such cases, while replacing the brake pads, it is also necessary to inspect the brake discs. Often, by the time this sound occurs, the brake discs may already be damaged. Even after replacing the brake pads, the noise may persist, and in severe cases, the brake discs may need to be replaced as well. 3. Feel the braking force: As brake pads wear thin, the braking performance is affected. You may need to press the brake pedal deeper to achieve the same braking effect that was previously achieved with a lighter press. The initial braking effect may noticeably weaken. If you feel that your brakes have become softer or less effective, it's time to check if the brake pads need replacement.
I just got new brake pads installed and need to pay attention to the break-in period. The new brake pads have a coating on the surface, so the braking performance might feel slightly softer or produce some noise initially, which is completely normal. For the first 200 kilometers, I should avoid sudden braking or continuous hard braking to allow them to gradually conform. For safety, it's best not to drive too aggressively on highways—instead, find a quiet road to test the brakes a few times and get a feel for the pressure changes. Additionally, regularly check the brake discs for any signs of wear. If there's vibration or unusual noise during braking that doesn’t go away, I should take the car to the shop immediately. After all, safe driving is the top priority—don’t ignore these details to save time, as it could lead to brake disc damage or sudden malfunctions.
After installing new brake pads, I need to adjust my driving habits. Avoid aggressive starts and apply brakes gently to give them time to adapt. Initial squeaking sounds are normal and should subside within days. I also checked the brake fluid to ensure proper levels and no leaks. When washing the car, avoid high-pressure water jets near the wheels to prevent rust. Before long trips, I test the brakes a dozen times in my neighborhood to ensure reliability in emergencies. Most importantly, avoid speeding or sudden maneuvers during the break-in period to prevent premature wear. If braking distance increases, revisit the mechanic promptly to address minor issues before they escalate.
