Not much braking power? How long do brake pads last? Find the answers here!

Summary: Many truck‑trailer drivers, when faced with ineffective brakes, will check the brake pads—this is beyond question. However, many people wonder: if the new brake pads start to lose effectiveness after only a short time, what could be the cause? And secondly, does this mean the braking performance isn’t up to par? There are several factors at play: 1. Whether the brake fluid is still within its recommended service life. Most truck‑trailer manuals advise regular replacement of the brake fluid. While this recommendation may seem somewhat conservative, it’s intended to ensure the driver’s safety. Over time, the performance of brake fluid degrades, which can reduce braking efficiency. Another key reason is that if air gets into the brake system—

Many truck drivers, when faced with ineffective brakes, will check the brake pads—this is beyond question. However, many people wonder: if the newly replaced brake pads lose their effectiveness after only a short time, what could be the cause? And secondly, does this indicate that the braking performance is not up to par? There are several factors at play here:

　　1. Is the brake fluid within its recommended service life? Many trailer manuals specify regular brake‑fluid changes. While this recommendation may seem conservative, it prioritizes the driver’s safety. Over time, brake fluid degrades, which can diminish its performance and reduce braking effectiveness. Moreover, even a small amount of air in the brake system can significantly impair braking performance.

 

　　2. Are the trailer brake pads up to standard? When the brake pads wear down to a certain extent, braking performance will deteriorate significantly, at which point they should be replaced. Moreover, even a tiny crack in the brake pads can directly compromise braking effectiveness.

 

　　3. Road conditions. In icy, snowy, or rainy weather, roads become extremely slippery, significantly increasing braking distances. Additionally, surfaces covered with sand, gravel, or excessive dust can also reduce braking performance. Braking effectiveness also varies between asphalt and concrete; under the same conditions, asphalt provides better stopping power than concrete.

 

　　Because trailer drivers apply the brakes at varying frequencies, it’s difficult to establish a fixed schedule for replacing brake pads. The proper approach is to assess the wear of your light‑truck brake pads during routine inspections, rather than replacing them strictly by time—always check their condition. If you frequently drive long distances, take a quick look when you stop: as long as there’s at least 5 millimeters of pad material remaining at the rivet opening, there’s no cause for concern. But if the pad thickness reaches the critical threshold, replace the brake pads immediately.

 

　　For long-haul trailer applications, Sait has specially developed drum brake pad formulations tailored to various travel distances, ensuring that wear performance meets customers’ basic requirements. These include the Yellow‑Mox low‑end series for up to 100,000 kilometers, the Golden Shield mid‑range formulation for around 150,000 kilometers, and the Tian Shield high‑end formulation for over 200,000 kilometers—ideal for rugged mountainous terrain and the top choice when replacing brake pads.
