It's Tuesday and sunny today, I woke up about 4:30 this morning, and then we drive to Shenyang airport, and we flew to Datong.
We rented a car to the customer side, and the customer said there was noise when the temperature of the rotor was high, he drived his car about 15 KMs and we listened the noise exactly, so we asked the customer to take down the break pads, and we found there ware some lighted places, so we use abrasive paper to grind these areas, and then we reassembled the pads, and drove again, and the noise didn't happened again.
And then we went to the second customer, he said his car had noise and shake issues, when we check the appearance of the pad and rotor, we found the assembled method was wrong, and we trained the operator how to assembly the pads, and we solved this issue also.
It was very busy today, and we had lunch about 3:30 this afternoon.
