Changing brake pads and rotors

前轮的刹车片和刹车盘好换，后的需要汽车诊断电脑收回电子手刹电机才能更换，

You jack the car up, remove the wheel, remove the caliper, remove the rotor, clean things up a bit, put the new rotor on, remove the pads from the caliper, clean it up, verify caliper operation, replace rubber seals if necessary, grease up the slides, grease the back of the pad, put the new pads in, put the caliper back, put the wheel back, lower the car, repeat 3 more times. There is likely a video on YouTube.
