Joylynn,
I always enjoy your intrepid attitude taking on these projects. The 2nd picture in your last post it appears the rotors are scoring or gouging in towards the hub. The first picture does not look bad. However remember that the pad clamp down on both sides of the rotors so there are four contact surface, 2 per wheel; so we are only seeing two in the pictures. Hard to be sure there is not further damage unseen.
In the old days the rotors (or disks) would be turned (cut) to a smooth surface for a small fee. the cost, hassle, and liability to workers has made that a rare practice in auto parts houses. Now they just sell you new rotors. Rotors "should be" smooth flat surfaces for the brake pads to be most effective. In a pinch I have thrown new pads on old rotors, but the cost (doing it yourself) is not worth doing the job a second time or prematurely. Also brakes are important. Why take chances.
Someone mentioned sticking calipers. A very good point. make sure the calipers are free to move as designed. However, don't step on the brakes with the caliper off the rotor. You might end up needing new parts as the pistons extend too far without resistance. If you have not seen it done yet, use a c clamp or other clamp on the inside/inboard pad to press it steady and gently back into the caliper. Then reattach the caliper over the rotor and have someone gently apply the brakes. You should see the pads come together on either side of the rotor smoothly and evenly. Then you will know they are not sticking.
Brakes are super simple to do once you get the hang of the procedures, except for this one little issue. Shims and clips. When you remove your pads from the calipers a lot of dust, road debris and possibly some metal "wafers" will fall out. Save these. remember/mark where they came from the best you can. Same with 'clips' These parts are there to help install the new pads into the calipers and keep them in place and in the appropriate plane. It is often overlooked. If they don't go back in the same, your pads may produce noise on the road. If you can't, or are not sure, it is not a safety issue per se. Your brakes will still work. They just may wear more quickly or make noise. But if you can get them back in the way they were, you will be happier.
Wear tabs were mentioned earlier. I just wanted to make clear the pads have metal tabs on the ends that stick out towards the rotors. As the pad material wears down, the tabs will start making contact with the rotors. This is designed to give you an audible que the pads are worn and will need to be replaced. The metal is softer than the rotor material, so they don't result in the scoring seen on rotors. It just sounds bad and may make one think their pads are completely worn.
Remember this with ramps as opposed to jack stands, how do you lift the tire off the ramp to remove the wheel? ramps are good for giving oneself a bit more room under the car for repairs like oil changes. They don't help if you have to pull a tire that is on the ramp. Get good jackstands and use them every time, all the time. don't rely on a jack. A jack is a hydraulic lift. That lift relies on little rubber o-rings to allow the fluid pressure to lift an object. If you are under a car and the rubber oring fails, the full weight of the vehicle is coming down on you. Don't bet your life on a 5 cent o-ring.
Have a good weekend, and take the advise "start early. go slow. document everything."
