What is the function of a car handbrake?

The function of the handbrake is to prevent the car from automatically sliding when unattended, avoiding traffic accidents. The following is a related introduction about the handbrake: 1. Introduction: The professional term for the handbrake is auxiliary brake. Unlike the principle of the brake, it uses a steel wire cable connected to the rear brake shoe to brake the car. Long-term use of the handbrake will cause plastic deformation of the steel wire. Since this deformation is irreversible, long-term use will reduce its effectiveness, and the travel of the handbrake will also increase. 2. Composition: It consists of a brake lever, cable, brake mechanism, and return spring, acting on the drive shaft or rear wheel brake to achieve vehicle stability.

It is mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises can even predict potential catastrophic damage to the engine. Therefore, when abnormal engine noises occur, timely repairs should be conducted to prevent further damage. Transmission Abnormal Noises: If there is a "rustling" sound inside the transmission while driving, which disappears when the clutch or accelerator is pressed, and a whistling-like sound occurs during gear shifting, it may indicate transmission issues. If the transmission noise is significant, it is recommended to send the vehicle to a professional repair shop to identify and replace the faulty component.

Do all 4 ignition coils need to be replaced when one fails?

No, only the damaged one needs replacement. Here's relevant information about automotive ignition coils: 1. Working principle: The automotive high-voltage coil (commonly called ignition coil) is one of the core components in gasoline engine ignition systems. To ignite the air-fuel mixture in engine cylinders, ignition energy is required, and the ignition coil serves as the medium to provide this energy, ultimately delivering spark through the spark plug. 2. Precautions: Avoid exposing ignition coils to moisture or excessive heat. Don't turn on the ignition switch when the engine isn't running. Regularly inspect and clean ignition coils to prevent short circuits. There's no fixed replacement interval for ignition coils - they don't need replacement as long as they function properly, with a typical service life exceeding 100,000 kilometers.
