rubbing sound in rt front tire coincides w/ tire rotation. Goes away when I so much as touch the brake pedal. I need brake pads but could the calip be sticking?? I got up to 50 today and it smelled like burning w/ slight white smoke. Also, temperature gauge that never worked before now spikes to hot for no reason ( I Have heat) and at the same time the low gas gauge comes on when I have plenty of gas. When the car stops moving the gauges return to normal. Mostly concerned about the tire as I need to take a two hour trip on sunday....
