What is the reason for the brake shoe alarm

Causes and solutions of brake shoe alarm:

1. Lack of brake fluid. Check whether there is no oil in the brake oil pot, if there is no oil, add brake oil.

2. The brake pads are worn to the limit. Disassemble the tire, check the thickness of the brake pads with a gauge, and replace the brake pads if necessary.

3. The circuit is short circuited. Use a multimeter to measure the four-wheel brake pad alarm circuit, the circuit of the brake oil level sensor, and the circuit of the handbrake switch for short circuit. If the circuit is short circuit, the sensor needs to be replaced and the circuit should be repaired.
