5 tips for the brake system of HM14-D concrete mixer truck

1. If the ABS warning light of HM14-D concrete mixer truck lights up, please check and deal with the service station as soon as possible to avoid affecting driving safety and delay time.

2. Release the brake after starting, and hear the friction between the brake pad and the brake disc which is normal phenomenon.

After the engine is started, the driver will step on the brakes before the gear is engaged. When the gear is engaged, the brakes will be released and the brakes will start to run. At this time, the brake pads and brake discs have been combined under normal temperature conditions, but they have not produced much. The friction will produce a forward or backward driving force when concrete mixer vehicle is in gear. When the brake pedal is released, the brake pads and the brake disc will produce a sound similar to “gugu”. This sound is more pronounced if the brake disc is wet after the cab is cleaned. The service brake system is a system that ensures that the vehicle can decelerate or even stop at any time according to the driver’s wishes.

3, after using a period of time, the hand brake track will be long, which is the normal phenomenon. The handbrake cable is composed of multiple sets of wires. It has a certain ductility after being stressed. After a period of use, it will have a certain elongation compared with the length of the new concrete boom truck, and will not have any impact on the parking brake. .

4. Brake disc rust: The main component of the brake disc is iron. If the mixer will not be used for a long time, and the surface of the disc will produce a certain amount of rust. However, when the car is running through the brake system, it will eliminate the rust, which does not affect normal use.

5. Heat phenomenon after use of the brake disc: it is the normal phenomenon. The brake is achieved by friction between the brake disc and the brake pad. It is a process of converting kinetic energy into heat energy, so heat is generated.
