What to Do When Your Car Breaks Down on the Highway

What does parking brake mean?

Parking brake is commonly known as handbrake. Its function is to provide resistance to the car when parking, preventing the car from rolling. The parking brake, also known as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. The force of the parking brake is much smaller than that of the service brake, just enough to ensure the car does not roll when parked on a slope. There are different types of parking brakes, such as the mechanical mechanisms operated by hand or foot as mentioned above. In addition, high-end cars are gradually adopting electronically controlled parking systems, commonly known as electronic handbrakes. The electronic parking brake system integrates the temporary braking during driving with the long-term braking after parking, and achieves parking braking through electronic control. The electronic handbrake is a technology that realizes parking braking through electronic control, and its working principle is the same as that of the mechanical handbrake, both of which achieve parking braking control through the friction generated between the brake disc and the brake pad.

What brand is radial tire?

radial refers to radial tires, with the international code R, and is not a brand. Radial tires: Radial tires were patented by Michelin in 1946. They are composed of two or three layers of steel belts cross-placed and adhered to the cord body. The carcass cords of radial tires run from one bead to the other, similar to the Earth's meridians, hence the name radial tires. Currently, most passenger car tires are radial tires. Advantages: Radial tires have many advantages over bias-ply tires, which is why they are the current standard in tire construction. Their advantages include: larger contact area, better adhesion, less tread slippage, lower unit pressure on the ground, lower rolling resistance, longer service life, thicker tread with a hard belt layer, and better puncture resistance.

What does the exclamation light in a car mean?

Car exclamation light is a conventional fault indicator light, which may light up due to the following reasons: 1. Overheating of the dry dual-clutch transmission clutch; 2. Intervention or malfunction of the fuel cut-off system; 3. Parking sensor failure; 4. External light failure; 5. Engine oil pressure sensor failure. The car fault light indicates that there is a virtual fault in the system, which can be cleared with an instrument to turn off the light. There may also be a soft fault in the system that needs to be checked and eliminated, but the soft fault at this time does not affect the starting of the car. It is recommended that the owner go to a repair shop to read the fault code with an instrument and clear the code.

What is a Dual Clutch?

Dual clutch refers to a dual-clutch transmission (DCT), which operates with two sets of clutches working simultaneously. One set manages the odd-numbered gears, while the other manages the even-numbered gears. The power transmission is achieved through two clutches connecting two input shafts, with adjacent gears alternately meshing with the gears on the two input shafts. By coordinating the control of the two clutches, it can change the transmission ratio without interrupting power, thereby reducing shift time and effectively improving shift quality. Different manufacturers have different names for dual-clutch transmissions: Volkswagen calls it DSG, Audi calls it Stronic, and Porsche calls it PDK. The advantages of dual-clutch transmissions include: fast shifting speed, low production cost, compact size, and low fuel consumption.

How to Completely Replace Antifreeze?

Method for completely replacing antifreeze: 1. Unscrew the radiator cap, open the radiator drain valve (usually located at the bottom of the car), and drain the antifreeze; 2. Clean the cooling system by continuously injecting clean water into the engine cooling system. During the flushing process, keep the engine idling to maintain the circulation of clean water inside until clear water flows out from the radiator; 3. Stop injecting clean water, wait for the water to drain completely, then close the drain valve; 4. Fill with new antifreeze until the liquid level is between the max and min marks; 5. Close the cap, start the car, and let the engine idle for two to three minutes. The cooling system will expel internal air, causing the antifreeze level to drop slightly. At this point, top up the antifreeze again.
