What Causes the Noise When Starting a GAC Trumpchi?

[MorganLee]

GAC Trumpchi starting with noise is due to brake noise, especially for new cars or newly replaced brake pads. The brake discs and pads need to break in, and noise is quite common. Brake Principle: The working principle of brakes mainly comes from friction. By utilizing the friction between the brake pads and brake discs (or drums), as well as between the tires and the ground, the kinetic energy of the moving vehicle is converted into heat energy through friction, bringing the car to a stop. A good and efficient braking system must provide stable, sufficient, and controllable braking force, along with excellent hydraulic transmission and heat dissipation capabilities. This ensures that the force applied by the driver on the brake pedal is effectively transmitted to the master cylinder and each wheel cylinder, while avoiding hydraulic failure and brake fade caused by excessive heat. Maintenance Methods: Under normal driving conditions, inspect the brake shoes every 5,000 kilometers. Not only should the remaining thickness be checked, but also the wear state of the shoes, whether the wear on both sides is even, and whether they return freely. Any abnormal conditions must be addressed immediately.
