Front driver side rotor grinded to ****! What's causing it? Well, it never ends... I pulled into my apartment complex today, and felt/heard a grinding noise coming from the brakes. I got out and looked at the rotor and this is what I saw. What the hell could do this much damage? It was only that 1 rotor.

Looks like your caliper isnt releasing. Could be caused by several things. This happened on my 96 Formula. The Pontiac dealer replaced the caliper. It was covered under the warranty. Take yours apart and make sure you lube all moving parts.

Have you replaced the pads recently? Did you replace the rotors or get them turned. Usually a very good idea to do so every time you change frictional parts. Same goes for changing the fly wheel when you replace the clutch. Lenghthens the life drastically.
Personaly I would take off the caliper and inspect the pad. Pad could be broken or could be down to the metal. I'm guessing the pad is toast b/c it looks bad accross the whole surface. Hard to tell unless you can see the other side of the pad.
One of my calipers siezed so I had to use a torch to get the slider pin out (this is what applies pressure to the opposite pad). Bought new pin's and boots for like 15 bucks at Autozone. It didn't do much to the rotor, but it was loud as hell. When I did this I also bought new rotors, pads, and guide plates.

either your caliper guide pins or piston have frozen or the brake pads have simply worn down.
also that should of been making noise a long time ago before it got that bad.

thats right you have a steel tab on your brake pad that will squeek like the most annoying noise you have ever heard. This happend to my friends Camaro and the caliper was seized. What happens is that the caliper pushed the center cylinder in and the springs over the bolts pull the pressure off the rotor (not an instant thing) this happens over a short time span of 3-5 minutes. It looks as though your caliper was not backing off the pressure and the more you used it the tighter it got and I would not be suprised if the car was not pulling that direction. Change the caliper completely or change the front pads but push the fluid back and forth thru the master cylinder a few times and then install the new pads.. then watch it like a chicken hawk for about 2 weeks and if the pad is worn down again then change the caliper. Sometimes this works and sometimes not but beats spending the $200 for a new caliper when all you had to do was work the flow of fluid.

another possibility is that you could of broken off the tab that creates that squealing noise. maybe your car is too loud for you to of heard it or something?
i've also seen aftermarket brake pads that didn't come with them.

Mine looked like that after my pads wore down. My car is way to loud for me to hear the wear bars, but I felt the grinding. Get the brakemotive set up, best bang for the buck. I have the front rotors with Hawk HPS pads and couldn't be happier. Very strong brakes that don't fade when hot.

Damn slash... That looks like you drove 20 miles with bald pads with the brakes applied the whole way. Make sure the slide pin is operating properly and the caliper is releasing. Good thing is calipers aren't very expensive if you don't want to rebuild them

the steel halo around the caliper was prolly hitting the rotor, due to very worn pads. the rotors are hardened steel only thing that can do this type of damage is a harder steel, the halo that your caliper bolts too is that harder steel. the caliper is aluminum (very soft metal) and the backing plate of the brake pads themselves are a softer steel, so those will not do that type of damage to the rotor. im willing to bet the halo is rubbing on the rotor.
