Driving without engaging the handbrake can lead to: 1. The brake system indicator light on the dashboard remaining constantly illuminated; 2. The vehicle's brake system indicator light typically activates when the handbrake is engaged and turns off when it's released. Driving without disengaging the handbrake will cause the indicator light to stay on, and some models may also display a text warning message on the dashboard screen. The professional term for the handbrake is auxiliary brake, which operates differently from the main braking system. It uses a steel cable connected to the rear brake shoes to apply braking force to the vehicle. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use will reduce its effectiveness and increase the handbrake's travel distance.

What Causes Brake Noise at Low Speeds?

There are several main reasons why brakes may produce abnormal noises during low-speed driving: 1. Brake pad break-in: New cars or newly replaced brake pads require a break-in period for optimal performance. 2. Foreign particles: Sometimes small particles like sand can get between the brake pads and rotors, causing noise due to friction. This usually doesn't require repair - driving for a while can help dislodge these particles. 3. Brake system malfunction: If the noise is accompanied by brake failure, immediate inspection and repair are needed. Missing or damaged brake rotor mounting screws, or insufficient lubrication can also cause brake noise.

How Long Does It Take for the Engine Coolant Temperature to Rise After Starting the Car?

Generally, it takes about 15 minutes for the coolant temperature to rise. Here is some information about car coolant temperature: 1. The temperature of the engine coolant should not be too low; it is generally recommended to keep it above 90 degrees Celsius. 2. You should not drive immediately after starting the car because the idle speed is quite high when the engine is cold, and the lubrication is not yet optimal. Driving at this stage will inevitably increase the engine load and accelerate wear. 3. The correct approach is to let the vehicle warm up naturally at idle until the coolant temperature begins to rise, and then wait for the idle speed to return to normal levels before driving.

Transit cars are categorized into two types based on their operational nature: non-switching transit cars and switching transit cars. Below is a detailed introduction about them: 1. Non-switching transit cars: Operational freight cars that are not detached in transit trains at technical stations and operational freight cars on suspended trains. 2. Switching transit cars: Transit cars that do not belong to non-switching transit cars. 3. Notes: When taking transit cars, it is important to reserve the time difference for transfers and pay attention to the intermediate stations for switching.
