Will the car slowly stop if the throttle is released when the brakes fail?

[VanKennedy]

Modern vehicles are all fuel-injected vehicles, and the engine will simply stop injecting fuel when the throttle is not pressed. Below is a detailed introduction about automotive brakes: Brakes: Brakes, also known as braking, refer to the action of stopping or reducing the speed of moving locomotives, vehicles, other transportation tools, or machinery. The braking device is a mechanical braking device that can slow down the speed of the vehicle, also known as a decelerator. Brake system: The brake system consists of a control system, hydraulic system, and power assist system. The control system includes the pedal, handbrake, etc. The hydraulic system is composed of hydraulic oil, brake pump, and hydraulic oil pipes. The power assist system is the vacuum power assist pump. The electronic control system consists of the ABS pump, ABS sensor, and ABS computer. The execution system includes the brake caliper, brake pads, and brake disc.

I've encountered similar situations while driving before. Brake failure is indeed quite frightening, but releasing the throttle will gradually slow the car down until it stops, though this depends on specific circumstances. For instance, at high speeds the deceleration is slower, and if going downhill, the car might continue coasting due to inertia even after releasing the throttle. I've personally tried this with manual transmission cars - engine braking is very noticeable after releasing the throttle, as the engine drags the wheels to reduce speed. Automatic transmission cars are less effective in this regard, especially at high speeds where deceleration isn't as obvious. You can't rely solely on this for safety because speed reduction takes time and the stopping distance might be too long. The correct approach is to immediately release the throttle to slow the car while quickly downshifting to lower gears to enhance braking, or use the handbrake for assistance. Remember the car will eventually stop due to air resistance and tire friction, but never take it lightly - quickly pull over to the side and have the brake system inspected at a repair shop afterward. These experiences were accumulated from numerous long-distance drives to avoid accidents in rush-hour urban areas.

As a car enthusiast, I've researched that the deceleration after releasing the throttle is called engine braking. The principle: the engine stops supplying fuel, but the wheels are still rotating, creating internal resistance in the engine that helps slow you down. It's easier with manual transmission cars - just downshift directly after releasing the throttle for stronger braking effect. Automatic transmission cars have similar functions in sport mode, but deceleration is gentler when releasing the throttle in normal gear. If the brakes fail, releasing the throttle can indeed gradually stop the car, but pay attention to road conditions: it works well on flat roads, is less effective uphill, and requires handbrake assistance downhill. It's ineffective in neutral gear - the car will just coast dangerously. In such emergencies, I recommend trying manual downshifting or using paddle shifters to let the engine help decelerate while planning a safe stopping point. From my highway driving observations at 80km/h, releasing the throttle reduces speed by about 2-3km per second, taking dozens of seconds to stop completely - safety first.

Releasing the throttle indeed slows the car down, as engine braking increases resistance when fuel supply is cut off, but the effect is limited. At high speeds, it may take 100-200 meters to stop, with manual transmissions being more responsive. The key is safe handling: don't panic if brakes fail - immediately release the throttle to control speed, then use the handbrake or downshift for assistance. It's recommended to pull over to a safe area to avoid accidents. Afterwards, a comprehensive brake system inspection is mandatory.

I used to drive older vehicles where the engine braking effect was very strong when releasing the throttle, causing the car to slow down quickly. Modern cars are more electronic, and the deceleration when releasing the throttle is less noticeable, especially for automatic transmissions in smooth mode. If the brakes fail, releasing the throttle can definitely help you slow down, but the time it takes to come to a complete stop depends on your speed. It is recommended to turn on the hazard lights to alert the vehicles behind you and find a flat place to stop and check. Regular brake maintenance can prevent such problems.

From a maintenance perspective, releasing the throttle when brakes fail is an emergency measure, as engine braking will gradually slow the vehicle to a stop. Manual transmissions perform better, while automatic transmissions provide gentler deceleration; however, if wheels lock or systems malfunction, deceleration will be slower. In emergencies, downshift, use the handbrake, and stop as soon as possible. Regular inspections of brake pads and hydraulic systems can reduce failure risks.
