Some Nissan Quest owners report experiencing smoking brakes even after replacing the drum, cylinder, and shoe components. This issue is often attributed to excessive heat generated from friction, which can result from hard braking, downhill driving, or malfunctioning calipers or wheel cylinders. Additionally, some owners note that new brake components may smoke during their initial break-in period as protective coatings burn off, although this should diminish over time. Improper bedding of new brakes can also lead to smoke, particularly if subjected to hard braking or steep descents. Furthermore, issues such as a stuck wheel cylinder, often caused by debris or corrosion, can keep brake shoes pressed against the drum, resulting in excessive friction. Lastly, malfunctioning brake systems or brake fluid problems can contribute to overheating and smoking brakes. It is essential for owners to identify and resolve the root cause of smoking brakes to ensure safety and optimal braking performance.
