Common sense about car brake system maintenance

Whether driving or not, everyone knows that the vehicle braking system is a system that ensures a vehicle can decelerate or even stop at any time according to the driver's wishes. It is directly related to the personal safety of passengers.
Below, please see the summary of the automotive braking system, 5 must-know common sense:
1. If the ABS warning light on the instrument panel lights up, please go to the 4S store for inspection and processing as soon as possible to avoid affecting driving safety and delaying the journey.
2. After starting, release the brake, and hear the friction sound between the brake pads and the brake disc. This is a normal phenomenon.
After the engine starts, the driver will step on the brake before shifting gears. After the gear is engaged, release the brake and the vehicle starts to drive. At this time, the brake pads and brake discs have already been engaged at normal temperature, but they have not produced much friction. After the vehicle is engaged, a forward or backward driving force will be generated. At this time, release the brake pedal, and the brake pads and brake discs will produce a sound similar to "gugu". This sound will be more obvious after washing the car if the brake disc is wet.
Recently, the advertisement "can't stop at all" has been circulating in every corner of the Internet, but it is not suitable for the braking system of a vehicle. The vehicle braking system is a system that ensures a vehicle can decelerate or even stop at any time according to the driver's wishes.
3. The handbrake cable will lengthen after being used for a period of time: This is a normal phenomenon. The handbrake cable is composed of multiple groups of metal wires, which have a certain ductility after being subjected to force. After being used for a period of time, it will be longer than the length when it was new, and it will not affect parking braking.
4. Brake disc rust: The main component of the brake disc is iron. If the vehicle is not used for a long time, a certain amount of rust will appear on the surface of the disc, but during the driving process, the work of the braking system will eliminate the rust and will not affect normal use.
5. The brake disc heats up after use: Normal phenomenon. Braking is achieved by the friction between the brake disc and the brake pads, which is the process of converting kinetic energy into heat energy, so heat will be generated. Do not touch the brake disc with your hands after parking to avoid burns.
