Is it safe to drive if the rear wheel smells burnt and the hub is very hot?
1 Answers
The causes of a burnt smell from the rear wheel and an overheated hub include worn hub bearings, insufficient bearing lubrication, and abnormal brake caliper retraction. Specific reasons are as follows: Worn Hub Bearings: If the hub bearings are installed too tightly or abnormally worn, it can cause the car's hub to overheat, and in severe cases, the bearings may burn out. Insufficient Bearing Lubrication: If the temperature is too high, the grease inside the bearings will melt and leak out, affecting braking performance and causing the hub to overheat. Abnormal Brake Caliper Retraction: If the brake caliper does not retract properly, it can cause the brake pads to lock, keeping them in constant friction with the brake disc. This results in brake drag, leading to increased temperatures in both the brake drum and the hub.
