2010 model year vehicles are exempt from OBD inspection. OBD (On-Board Diagnostics) is an automotive self-diagnostic system with the following functions: 1. Locating and describing faults in specific components to facilitate repairs; 2. Alerting when faults cause excessive emissions, indicating increased environmental pollution. OBD systems include: 1. EGR; 2. Engine; 3. Particulate filter; 4. Catalytic converter; 5. Oxygen sensor; 6. Emission control system; 7. Fuel system. OBD working principle: When emission-related faults occur, the ECU records fault information and corresponding codes, then notifies the driver through illumination of the malfunction indicator lamp or check engine light.

What damage can driving with the handbrake on cause?

Driving with the handbrake on can cause the following damages: 1. Accelerated wear of the brake discs and hardening of the brake pads due to overheating, leading to reduced braking performance; 2. Excessive wear of the handbrake's brake pads, resulting in damage to the drive shaft; 3. Locking of the rear wheels and snapping of the brake cables, which may cause skidding or rollover. The function of the car handbrake is to provide braking when parking on flat or inclined surfaces, preventing the vehicle from moving automatically when unattended. The principle of the car handbrake is to connect to the rear brake shoes via a steel cable to apply braking force. Precautions for using the handbrake while driving: 1. Do not pull it too tightly; 2. Avoid using the handbrake for prolonged parking on slopes; 3. Do not engage the handbrake after washing the car in snowy or icy conditions.

Must Brake Pads Be Replaced at a 4S Shop?

Brake pads do not necessarily need to be replaced at a 4S shop. The steps for replacing brake pads are as follows: 1. Open the engine compartment to check the brake fluid level to prevent overflow during the replacement process; 2. Remove the wheel where the brake is located; 3. Unscrew the bolts of the brake caliper and remove the brake pads; 4. Install the new brake pads, tighten the guide bolts, and complete the replacement. Types of brake pads include: semi-metallic brake pads, non-metallic brake pads, carbon fiber brake pads, and ceramic fiber brake pads. The working principle of brake pads is to convert the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and the brake drum, as well as between the tires and the ground, thereby bringing the vehicle to a stop.

Which One is the Brake in a Manual Transmission?

In a manual transmission, the leftmost pedal is the clutch, the middle one is the brake, and the rightmost is the accelerator. Only manual transmissions have a clutch pedal; automatic transmissions do not. In an automatic transmission: the left pedal is the brake, and the right is the accelerator. Precautions for car operation are as follows: 1. When shifting gears while driving: Press and release the clutch pedal quickly, avoiding partial engagement, as this can accelerate wear on the clutch disc. 2. During normal driving: Do not rest your left foot on the clutch pedal for extended periods, as this can lead to rapid wear of the clutch disc. 3. When braking: If the speed after braking is not very low and the car does not need to shift gears, do not press the clutch pedal.
