What is the foot brake?
2 Answers
Foot brake is the service brake. The following is a related introduction to the classification of braking systems: 1. Service brake: It is a braking device that stops or reduces the speed of a running car. It completes braking through the intense friction between the brake pads and the brake drum. The handbrake is a parking device and should not be used for braking during driving except in emergency situations. 2. Throttle control braking: When deceleration is needed, maintain the gear in 3rd, fully release the throttle. At this time, the engine tends to idle, thus creating a resistance to the transmission system, acting on the wheels to slow down the vehicle. 3. Exhaust brake: There is a butterfly valve at the connection between the exhaust manifold and the exhaust pipe of high-power diesel engines. When in gear, operate the electromagnetic switch to close it, causing the engine to stall and achieve the braking effect. It will automatically open when the throttle is pressed again. The structure is simple but harmful to the engine. It is currently widely used in heavy trucks and buses.
I've been driving for nearly twenty years, and the foot brake is what we commonly use as the brake pedal while driving. Every time I see a red light or a car ahead, my right foot naturally presses down to slow the car. It transmits braking force through the hydraulic system to the brake calipers on all four wheels, causing the brake pads to clamp onto the brake discs, which slows the car down. This is completely different from the handbrake, which is pulled up after parking to prevent the car from rolling. The foot brake is the main tool for controlling speed while driving. You should avoid slamming on it too hard in daily use, as it can easily cause rear-end collisions, and be especially gentle when braking in rainy weather. If the pedal feels soft when pressed, it's crucial to check the brake lines or the brake pump immediately.
