Is it harmful to drive 5 kilometers with the handbrake on?

The most immediate hazards include accelerated wear of the brake discs, hardening of the brake pads due to overheating, and elongation of the handbrake cable. This leads to a decline in braking performance and can sometimes produce a burning smell. In severe cases, smoke may emerge from the rear of the vehicle. Prolonged driving with the handbrake engaged may also cause the brake caliper to seize, brake fluid to leak, or the brake fluid temperature to rise excessively, resulting in a complete loss of braking function. Here are some key points about why you should not drive with the handbrake on: 1. Stay vigilant while driving: If you notice that you've been driving with the handbrake engaged and detect a strong burning smell or see smoke from the rear, immediately reduce speed, apply the brakes, and release the handbrake. Do not continue driving. Pull over to the side of the road, allow the vehicle to cool down, and carefully inspect for any other abnormalities. Never simply release the handbrake and continue driving while the vehicle is still overheated. 2. Regular inspections: The handbrake is frequently used during vehicle operation. However, it is not a "foolproof safety feature"—its effectiveness diminishes with repeated use. Often, even when the handbrake is engaged, system failure or improper use can render it ineffective, potentially leading to accidents. Drivers must pay close attention and should regularly maintain and inspect their vehicle's handbrake.
A friend of mine had this experience - he drove 5 kilometers with the handbrake on. Honestly, this is no small matter. The braking system suffers continuous friction, causing the brake pads to overheat, deform, and wear out faster, and may even burn the tire treads. At the time, he smelled something burning and immediately stopped to check, finding the rear wheels scorching hot. The repair cost over a thousand yuan to replace the parts. What's more troublesome is if the braking performance declines during emergency stops next time, that could be dangerous. I suggest you drive to a repair shop immediately for a comprehensive inspection of the brake discs, pads, and tires - don't wait until the problem worsens and affects safety. Make it a habit to confirm the dashboard lights are off before starting the car.
As someone who knows cars well, I must say driving 5 kilometers with the handbrake on is absolutely problematic. Brake components already operate under high pressure, and prolonged friction will cause rapid temperature rise, damaging the lifespan of disc or drum brakes. You might notice abnormal tire wear or weakened braking performance - these warning signs shouldn't be ignored. I recommend doing a simple self-check when you have time: after parking, feel if the rear wheel hubs are hot and listen for any dragging noises. If you notice anything unusual, get professional inspection immediately to prevent more serious engine or drivetrain issues. Safety comes first, and regular checks can also save you a fortune in repair costs.
