The Four-Wheel Anti-lock Brake System (ABS) is an electronically oreeatpd, all wheel brake control system. Major components include the power brake booster, master cylinder, the wheel speed sensors, and the Hydraulic Control Unit (HCU) which contains the control module, a relay, and the pressure control valves. When anyone of these malfunction the ABS Light will come on. Reference:

you forgot the most inpartomt part man. I would hope that you torque the wheels on once the vehicle is lowered if not you will be sued one day for someones wheel/wheels falling off either from over torque or not enough torque. You could kill someone or from your video basicly inform someone that there is no need to torque your wheels. I didn't see a torque adapter on that gun and even if there was I still wouldn't be impressed. The only way to torque is with a proper calibrated torque wrench.

You can replace pads wihtout bleeding brakes. I would not recommend anyone wihtout professional experience to remove a brake hose, release a bleeder valve or bleed brakes. At the very least have someone who has done it a few times before help you. If you get it wrong best case scenario you smash up your vehicle. Remove the brake master cylinder cap and press the piston back with a C clamp. If it does not go back caliper is bad, replace it, then you will have to bleed brakes.
