Bought it with a soft brake pedal. Vacuum holds when pumping brakes, replaced master cylinder and bled brakes, got better, but after reading on it turned out these have mushy pedal. VSC off light sometimes comes on when I start it, once I drive off, it goes away. Also, this has a button to change from 2 to 4wd, when in 4wd is it supposed to be this hard to move the car on a driveway when in 4wd mode and wheel turned? I scanned it and got these codes. I replaced the battery as it kept on dying, not sure of codes were from before or after battery replacement.

Please start a new question for the "button to change from 2 to 4wd, when in 4w" issue, we only handle one problem per thread. For the mushy brake pedal it sounds like one of the caliper slides is seized and the caliper is not "floating" as it should. If there could be more than one causing it, I would remove the wheel and back the pads off to check the caliper slide action. Here is a guide to help you:

Also, you may want to bleed the system with a CAN scanner to open the ABS valves. This video will show you how:

Please let us know what happens after you check the slides.

I just remembered there is also a vibration, a harsh one while driving, that could be a sticky caliper if am not mistaken.

Put all wheels in the air. One of the pins on the front is jammed, so took forever to get it out and I lubricated all 4 wheels, I will bleed again and see.

Unreal how the brake pedal feels after I lubricated all 8 pins. The front caliper has a plastic sleeve on the bottom pin and no matter what I did it won't go back in with it on the pin. So, I removed it and put it back to see. All good for now. Didn't even have to bleed it again. Are those plastic sleeves very important?

They might keep the caliper from rattling, if you load an image of what you are talking about, I can tell for sure, glad you got the problem solved.

Yep, that will help the caliper be quiet while not it use. Kind of like a dampener.
