Parking brake refers to the handbrake, while service brake refers to the foot brake. The differences between service brake and parking brake are as follows: 1. The parking brake is the handbrake, mainly distinguished from emergency braking, which refers to immediately applying braking measures upon discovering an emergency situation to bring the vehicle to a stop in the shortest possible time. Engine braking utilizes the engine's resistance to implement braking, such as during long downhill descents where prolonged use of the foot brake could overheat and damage the brake pads. In such cases, shifting to a lower gear and coasting at idle speed can help control the vehicle's speed using the engine's resistance. 2. The brake is the foot brake. Brakes are divided into service brakes (foot brake) and parking brakes (handbrake). During driving, the service brake (foot brake) is generally used to slow down or stop the vehicle while moving forward, not just to keep the car stationary. The parking brake is only used when the service brake fails. Once the vehicle is stationary, the parking brake (handbrake) should be applied to prevent the vehicle from rolling forward or backward. 3. After parking, in addition to using the parking brake, it is recommended to shift into first gear when parked on an uphill slope (to prevent rolling backward) and into reverse gear when parked on a downhill slope (to prevent rolling forward).

What Are the Reasons for a Car Not Starting After Rain?

The reasons for a car not starting after rain include faults in the wiring, fuel lines, and battery. Below are the relevant explanations: 1. Wiring and Fuel Lines: Since most of the vehicle's wiring and pipelines are concentrated in the engine compartment, if the vehicle is driven through water, it is inevitable that the internal wiring and pipelines will get splashed with water. Over time, this can easily lead to short circuits in the wiring and blockages in the fuel lines, with the most direct fault being the car not starting. 2. Battery: At low temperatures, the battery's output power decreases due to increased viscosity of the electrolyte, reduced permeability, and increased resistance, making it difficult for the starter to crank the engine to the minimum starting speed, thus affecting engine startup. Additionally, the low terminal voltage of the battery results in weak sparks from the spark plugs, and the increased resistance between electrodes due to the dense mixture makes it difficult to ignite the mixture, which is another reason for the engine's difficulty in starting.

Can a newly purchased car be driven on the highway?

Newly purchased cars can be driven on the highway. Safety first, a valid driver's license is required. Below are relevant details about driving a new car on the highway: 1. Driving recommendations: During the break-in period, you can drive on the highway, but it's advisable not to exceed 100 km/h. Also, avoid driving continuously for too long; generally, it's best not to exceed 2 hours. Occasionally vary your speed rather than maintaining a constant speed, as too uniform driving conditions are not conducive to the break-in process. 2. Highway driving conditions: New drivers can drive alone on the highway only after holding a driver's license for at least one year. Those who have held a license for less than a year must be accompanied by someone who has held a license for at least 3 years when driving on the highway.
