Car brake pad induction line action
The main function of the brake pad induction line is to monitor the wear of the brake pads, and trigger an alarm signal when the brake pads are worn to a certain extent, reminding the driver to replace the brake pads . Specifically, the brake sensing wire, through the design of the circuit and spring steel, will cut the sensing wire when the brake pad reaches the wear limit, which triggers the red alarm light on the instrument panel .
Working principle
The working principle of the brake sensor line is based on the wear condition of the brake disc. When the brake disc is worn to a preset critical point, the natural circuit of the induction wire is cut, and this physical change is then converted into an electrical signal and transmitted to the car's electronic control unit (ECU), which activates an alarm light to remind the driver .
Maintenance and replacement
Under normal circumstances, when the brake alarm light comes on, the driver will replace the brake pads and replace the induction line that has been cut off at the same time. However, if the brake pad has not been worn to the limit and replaced in advance, the induction line can not be replaced .
In addition, the installation and maintenance of the induction line also needs to pay attention to whether the pin is bent or welded well to ensure the accuracy of signal transmission .
The induction wire of the brake pad is broken and needs to be replaced with a new induction wire . A broken brake pad induction line usually means that a replacement operation is required. For owners of BMW 325 series, although you can choose to cut and reconnect the induction cord at the appropriate location, this practice may bring inconvenience, so it is recommended to go to a professional auto repair shop for treatment .
Replace the brake pad induction line steps
Clean the induction cable : Clean the induction cable and its surrounding area to ensure that it is free of dust and impurities.
Replace the new induction cable : install the new induction cable in place and fix it according to the previous position. The sleeve on the induction line can be moved, and it can be adjusted if it does not correspond to the buckle on the car body.
Tidy up the wiring harness : Tidy up the excess wiring harness and try to keep it away from the hub to reduce friction and wear .
Install the tire : put the tire back to the original position, start the vehicle for inspection, to ensure that the induction line is working normally .
The influence of induction line fracture on driving safety and preventive measures
fault light on : If the fault light is on, it means that the brake pads need to be replaced to ensure driving safety .
ABS on : If there is a problem with the sensor line, the ABS light will light up. At this time, it is necessary to check and replace the induction line .
Regular inspection and maintenance : Regular inspection of all components of the brake system, including induction wires, to ensure that they are in good condition. Use lubricants and maintenance tools to extend the life of the induction line .
