What causes the burnt smell after driving a few hundred meters without releasing the handbrake?

[VonChase]

Driving without releasing the handbrake causes a burnt smell because the unengaged handbrake accelerates wear on the brake discs and overheats the brake pads, making them harden. The handbrake cable may also stretch, reducing braking performance and producing the burnt odor. The hazards of driving without releasing the handbrake are as follows: Severe wear on the braking system: Forgetting to release the handbrake in an automatic transmission vehicle causes severe wear on the braking system. It can also rapidly increase the temperature of the automatic transmission fluid, leading to fluid degradation. Impact on the engine: Additionally, it leads to premature wear of the clutch plates inside the transmission. The faster the speed when driving without releasing the handbrake, the greater the damage to the braking components, and it may also cause some tire damage. In severe cases, it can even affect the engine.
