Well sometimes the back brakes stick and release on my truck. No kind of check light came on but the tire pressure monitor light. What part do I nned for this problem?

Maybe a bearing going?

it turns over and tries to start but will not. Thinking the ignition switch is bad. Any input is appreciated...

The middle right bucket seat belt retaining bolt came loose and is lost. Once I obtain a new one, how do I replace the retaining bolt?
