The handbrake fault code is a warning for the electronic handbrake system maintenance. The main causes include lack of necessary maintenance, improper operation, and severe overload. Lack of necessary maintenance: Too much impurity in the brake master cylinder, poor sealing, failure of the vacuum booster pump, dirty brake fluid or mixed use of several types of brake fluid causing air resistance after heating, leakage in the brake master cylinder or wheel cylinder, leakage in the air reservoir or pipe connections. Improper operation: Long downhill driving can cause the brake pads to generate heat through friction, carbonization of the brake drum, and complete failure of the braking function. Severe overload: Under the effect of gravitational acceleration, the vehicle's motion inertia increases, directly leading to brake failure.

Does the Radiator Need Cleaning?

The radiator needs cleaning. If left uncleaned for a long time, it can easily develop rust and scale, which significantly reduces the cooling system's heat dissipation efficiency and may cause the radiator to boil over. In severe cases, it can damage the engine. Cleaning steps: 1. Ensure the engine is cooled down and turned off; 2. Remove the radiator cap, making sure the engine is cool; 3. Open the drain plug at the bottom of the radiator to let the coolant flow into a bucket; 4. Close the drain plug and fill the radiator with water; 5. Start the engine, turn on the heater control system, add cooling system cleaner, and let the engine idle for 30 minutes; 6. Turn off the engine, let it cool for 5 minutes, then drain the liquid from the radiator; 7.

What are the reasons for the surge in failure rate of GAC Trumpchi GM6?

The reasons for the surge in failure rate of GAC Trumpchi GM6 are as follows: Weak power: All models of Trumpchi M6 are equipped with a 1.5T turbocharged engine, paired with a 6-speed manual or 7-speed wet dual-clutch transmission, delivering a maximum horsepower of 169 and a peak torque of 265 Nm. Although the power parameters seem decent, the vehicle actually feels sluggish during acceleration, and the power reserve for high-speed overtaking is slightly insufficient. Gear shifting possible after engine shutdown, posing serious safety hazards: The gear lever locking design of Trumpchi GM6 has obvious defects. The issue manifests as the gear lever easily disengaging from its original position when lightly shaken up and down after parking and turning off the engine. If in doubt, one can test this with an actual vehicle. Such a defect carries severe safety risks. For instance, if a child accidentally moves the gear lever from 'P' to 'N', causing the vehicle to roll, the consequences would be unimaginable.
