What is the reason for severe heat in the left rear wheel of a Santana?
2 Answers
Here are the reasons for severe heat in the left rear wheel of a Santana: 1. Friction: Prolonged friction between the tire and the ground generates heat, which is conducted to the wheel hub, causing its temperature to rise. 2. Braking: Extended braking causes the brake pads to generate high temperatures, which are then conducted to the wheel hub, leading to increased temperature. Below is additional information related to tire pressure: 1. Function of low-pressure tires: Low-pressure tires are mainly used for private cars. 2. Function of high-pressure tires: High-pressure tires are primarily used for large trucks or passenger vehicles. 3. Tire pressure: The recommended tire pressure for high-speed driving is 2.5 kilograms per cubic centimeter.
I've been driving a Santana for many years, and it's quite common to encounter overheating in the left rear wheel. Usually, it's due to issues with the braking system, such as a stuck brake caliper that fails to release, causing the brake disc to continuously rub against the brake pads and generate heat. Alternatively, the bearing lubricant may have dried up, leading to excessive friction and rapid temperature rise during rotation. Low tire pressure can also cause the tire to overwork and heat up easily. Sometimes, uneven distribution of brake fluid results in excessive pressure on one side. If not addressed promptly, the wheel hub may deform or even cause a tire blowout, which is quite dangerous. After parking, I often touch the wheel hub to check its temperature—if it's noticeably hotter than the other wheels, caution is needed. Regular checks on the flexibility of the brake caliper, any abnormal noises from the bearings, and maintaining proper tire pressure can prevent this issue. If detected, head to a repair shop immediately for inspection—don't delay until it becomes a bigger problem.
