Is there any impact if the foot brake is not released for several kilometers?

As long as you don't frequently drive with the foot brake engaged, the impact is minimal and there's no need to worry too much. Below is a related introduction to the classification of braking systems: 1. Service brake: This is the braking device that stops or reduces the speed of a moving vehicle. It achieves braking through intense friction between the brake pads and the brake drum. The handbrake, on the other hand, is a parking device and should not be used for braking during driving unless in emergency situations. 2. Throttle control braking: When deceleration is needed, maintain the gear in 3rd, fully release the throttle. At this point, the engine tends to idle, creating a resistance in the transmission system that acts on the wheels to slow down the vehicle. 3. Exhaust brake: High-power diesel engines have a butterfly valve at the connection between the exhaust manifold and the exhaust pipe. When in gear, operating the electromagnetic switch closes this valve, causing the engine to stall and thus achieving a braking effect. It automatically opens when the throttle is pressed again. This method is simple in structure but can damage the engine. Currently, it is commonly used in heavy trucks and large buses.
Driving several kilometers with the parking brake engaged can have significant consequences. The brakes remain under resistance, causing excessive friction between the brake pads and rotors, leading to severe wear or even warping. With decades of driving experience, I've often seen beginners forget this, resulting in overheated brakes emitting foul odors—extreme cases may even cause them to glow red and fail, compromising driving safety. Fuel consumption also increases because you need to press the accelerator harder to overcome the resistance. Upon arriving at your destination, it's best to immediately stop and check the brake area for unusual smells or excessive heat, then test if the brakes function normally. Newer cars with electronic parking brakes may have warning alarms, but older models require extra vigilance. Developing the habit of confirming the brake is released before driving is wise—it prevents unnecessary repair costs.
