I just put new pads and rotors on in the front, and i noticed that after i finished driving for about 20 minutes, the right rim was very hot, and smelled as if something was burning. The left seemed perfectly fine.
Is this caused to a sticky slider?

If this helps, someone stole two of my lug nuts and i didnt notice, and i drove down the road and 15 seconds later my car started thumping and jumping around and i didnt know what it was, and when i realized someone took my lugnuts, i put new ones on. but when i did that i seen that my rim looked warped and where the studs go through the rim to sit on that car, the studs seemed to mess that area up a bit. but the rim went back on just fine, and thats when i noticed the smell and warmth.

Is my caliper broke?

 

Your caliper pins may be stuck or your caliper piston is stuck too far out. Did you push the piston all the way back into its bore, and did it move smoothly or did it bind up?

Take the caliper off and see if the pins slide freely in the bracket.

 

did you remember to grease the sliders and to wipe down the pads and rotors with BPC before you drove with them ?.

 

one of the pins that holds the pad to the rotor is broke so its hoding one pad in place and not the other...
and no i forgot to use brake cleaner...

so i should remove the caliper and push the sliders back and see if they slide freely back and forth? if they do then what? if they dont??

 

Lol.....

You need both pins. If one broke, then it might be something youd mention when trying to trouble shoot brakes.

The pins need to move freely. There need to be 2 pins.

If they don't move freely, free them, wire wheel or replace them. Regrease them with high temp lubricating grease (not anti sieze), and re assemble them.
