So on my new 240 it had pretty worn pads and warped rotors I think, but the brakes worked fine and they didn't drag. Today, I decided it's time to swap new ones on. So I took the rotors and pads from my old 240. They didn't have much wear on them, and they were good.

Started with the back ones. Such a pita. First of all, couldnt get the piston back in, the bleeder valve was clogged, unclogged it, still couldnt get it in, so i detached the caliper and took it into the garage to work on it. Couldnt push it in, messed around a bit, took piston all the way out, realised it screws in so i screwed it all the way in, and assembled the brakes. Had little issues throughout the process, had to call it a day after getting just the rear ones assembled.

Took it out for a test drive. And the brakes drag. I raged. One thing I can't stand is dragging brakes. I had way way less coasting distance. It was dark by now so I couldnt work on them some more, but my passenger side brake area smokes after driving, the whole area is damn hot, even my rim. This was the side that I took off and into the garage.

Checked other side, and it doesnt smoke, and its not hot. But, the rotors i swapped on had rust on them, which had dripped down when it rained, it will come right off when braking. But only half of the rust wore away. The outer area of the rotors didnt wear away at all. Only maybe an inch of the rotor wore down to shinyness.

On a note, I messed with alot of random things on the caliper, and i probably caused this, but when i pull my ebrake, it only comes up to maybe half way, or a bit less. It used to come twice as much up as it does now. And when I was driving, after a while I was able to coast a bit more, it was more free, but I could still feel the dragging. And when I was driving, I could hear a rubbing noise from the wheel, not sure if it was both wheels, but i know the drivers side rear wheel has a rubbing noise, not a constant one, but a steady one, so i assume it goes with the rotation of the wheel.

I know it's alot to read, but if anyone can help me, and explain this, I will be so so so thankful

mainly the ebrake part, i think if i solve that i'll solve the problem

sounds like the ebrake cable is twisted or installed back on wrong to get it to drag. i always put on new pads no matter what rotors i install, just for the fact that the seat a certain way, then when changed need to reseat, so you will get uneven wear and the pads will wear out faster, not to mention just not work as well. i would pull them all apart, make sure the piston is not binding up when you screw it in and out, then reinstall. make sure to do it slow, nothing should take forcing, it will only go on easily the right way.
