Oil Change turned into 100,000-mile Service Party | Brakes | ABS | Tire Rotation | Fluid - Lexus RX

I started with an innocent oil change... but somehow ended up throwing a full-blown 100k-mile service party. I'd call it a delightful series of automotive adventures!

After I raise the car to do an oil change, I take off the wheels for a front brake job; now I have taken off the front wheels, I remove the rear tires as well for a tire rotation; and once all wheels are off, let's do a brake bleeding; if I am to perform brake bleeding, why not bleed and purge air from the ABS as well?
