There are several reasons that can cause car brake failure, including lack of necessary maintenance of the braking system, severe overloading, and improper operation leading to mechanical failure. Lack of necessary maintenance of the braking system: too many impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, excessively dirty brake fluid or mixing different types of brake fluid causing air resistance when heated, leakage in the brake master cylinder or wheel cylinders, or air leakage in the air reservoir or pipe connections. Severe overloading: under the effect of gravitational acceleration, the vehicle's motion inertia increases, directly leading to brake failure. Improper operation leading to mechanical failure: for example, prolonged downhill driving can cause the brake pads to generate heat through friction, carbonization of the brake drum, and complete failure of the braking function. Correct measures to take after car brake failure: promptly identify the issue and decelerate to stop, avoiding continued high-speed driving; use the handbrake appropriately to control the vehicle, avoiding pulling it all the way or too quickly. Shift to a lower gear appropriately to control the speed.

What does it mean to check the engine emission control system?

Checking the engine emission control system indicates that there is a component issue with the vehicle's engine, and the engine warning light illuminates to alert the owner to inspect the engine components. The engine emission system fault light, commonly referred to as the engine fault light, will illuminate on the dashboard when the ECU detects and reads a fault code. The engine can refer to both the power generation device and the entire machine including the power unit (such as gasoline engines, aircraft engines). Its types include internal combustion engines (e.g., gasoline engines), external combustion engines (e.g., Stirling engines, steam engines), gas turbines (used in racing cars), electric motors, and more.

What kind of engine oil is best for GAC Trumpchi GS3?

Trumpchi GS3 uses 5W30 engine oil, which has good low-temperature fluidity, can be used in various weather conditions, and has excellent lubrication capabilities. It is the most commonly used type of engine oil in the market. The viscosity of engine oil changes with temperature, so special attention is needed to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in Trumpchi GS3 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back to the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until no more oil flows out. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain; Use a specialized wrench to remove the oil filter; Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add new engine oil through the oil filler cap on the engine valve cover. Generally, fill up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the dipstick to check that the engine oil level is within the standard range.
