The automotive brake pad alarm line is an important device used in the braking system, which serves to alert the driver when the brake pads are worn to a certain extent. This article will focus on exploring the working principle and maintenance methods of the automotive brake pad alarm line, in order to improve the understanding and maintenance level of the braking system for car owners.
The working principle of the brake pad alarm line is that when the brake pad wears out for a certain period of time and reaches the "limit" set by the brake pad, the natural circuit is "broken" by grinding, and then it is also eroded to the ECU and the alarm light is turned on. The brake pad alarm reminds the owner to replace the brake pads in a timely manner. Extended information: Brake alarm line: The brake alarm line is generally composed of steel plates, adhesive insulation layers, and friction blocks. The steel plates need to be coated to prevent rust. During the coating process, the SMT-4 furnace temperature tracker is used to detect the temperature distribution during the coating process to ensure quality. The insulation layer is composed of non heat transfer materials, with the purpose of insulation. The friction block is composed of friction materials and adhesives, which are squeezed onto the brake disc or drum during braking to generate friction, thereby achieving the goal of vehicle deceleration and braking.
The service life of automotive brake pad alarm lines is closely related to their material quality and normal use. Generally speaking, the maintenance methods for automotive brake pad alarm lines mainly include the following aspects:
Regular inspection: Check if the wear detection wire is in contact with the brake disc to avoid wire damage or damage, which may cause the alarm to fail.
Maintenance: Drivers should regularly check the wear of brake pads and the condition of drums and axles, and pay attention to regular replacement and maintenance.
Attention to driving: Avoid excessive use of brakes during prolonged high-speed driving conditions, and reduce unnecessary loads on the vehicle.
The car brake pad alarm line plays a very important role in the braking system. Its working principle is achieved through an induction circuit, and the alarm sound can help the driver replace the brake in a timely manner
