My suburban has announced it needs new brakes/rotors with lots of grinding. So I have new pads and new rotors and plan on doing the work myself. I am wondering about brake bleeding, etc. The brake pedal has been spongy as long as I can remember. I have never bled the brakes. I am hoping that new brakes/brake bleed will solve the spongy brake pedal. Wondering if you can give any guidance on the spongy pedal/brake bleed procedures for best results.

Brake bleeding is fairly simple. One good method is to get a large clear glass or plastic jar and put some brake fluid in the bottom not a lot is required, use a clear plastic hose that fits over the bleeder and place other end into jar with brake fluid. Open bleeder and pump pedal slow down, not all the way about 3/4 stroke and return to top, bubbles then fluid will start to come from brakes into jar, (with each stroke) the hose in the fluid will stop air being drawn up into the brakes, pump pedal slowly until fresh fluid is seen flowing in the hose. With the pedal down, lock off the bleeder and move on to the next wheel, do all four rear rear first then front, this method should work for you.
