Will rust on the brake pads affect it?

In today's society, cars have become a common sight on the roads as they serve as a vital mode of transportation for people. However, owning a car is still a luxury that many ordinary families cannot afford. Hence, those fortunate enough to own a vehicle are extremely cautious and attentive when it comes to maintenance. While car owners primarily focus on safety features and significant components, they often neglect the significance of smaller accessories like brake pads. Despite their unassuming appearance, these accessories play a crucial role in ensuring the car's optimal performance and safety.

There is no specific timeframe for brake pad replacement as it varies depending on various factors. When you take your car to a 4S shop for maintenance, the management staff might recommend replacing the brake pads without even inspecting them, which can be considered highly irresponsible. Unlike oil and filter element replacements, which have fixed intervals, other maintenance items require examination to determine whether replacement is necessary. Typically, brake pads are replaced between 30,000 and 80,000 kilometers, but the actual mileage can differ significantly. If you frequently use your brakes, it's advisable to replace them earlier, while frequent driving at lower speeds may delay the replacement. Additionally, the type of brake pads used also plays a role, as softer pads may require replacement sooner.

If you have your vehicle's maintenance done at a 4S shop or repair shop, then the technician will usually only check the thickness of the brake pads during each maintenance check. However, this may not provide enough predictive ability for the next maintenance check. In this case, it is important to replace the brake pads when needed. However, if you maintain your car yourself, there are some things to keep in mind. Firstly, you should look at the mileage of your car. If it is less than 30,000 kilometers, you can inspect it yourself by using a flashlight to check the thickness of the brake pads. If it is more than 30,000 kilometers, you may need to inspect it more closely by taking off the tires. Each wheel has two brake pads - one on the outside and one on the inside. While most cars have similar wear on the inner and outer brake pads, some cars can be different. With these factors in mind, it is important to regularly monitor the wear of your brake pads to ensure your own safety and that of others on the road.

Once the tire is removed, both the inner and outer brake pads become clearly visible, allowing for a more accurate assessment. It is crucial to view them directly rather than at an angle from the outside, as this can lead to inaccurate thickness readings, especially for those with limited experience. Generally, it is recommended to replace the brake pads when they wear down to 3 mm. In the case that there is still 5 mm thickness remaining after removal, it would be advisable to inspect them during the next maintenance session. However, if there is still a substantial 1 cm thickness, it is evident that the brake pads are still considerably thick, eliminating the need for disassembly in the near future. It's worth noting the presence of a warning disc that comes into play when the brake pad is worn down to its limit. At this point, the brake pad will come into conflict with the brake, resulting in a distinct and potentially sharp sound. It is important to be mindful of any unusual sounds produced by the thin brake pad and respond promptly by gently applying the brakes.
