Ugh, just take it to a mechanic man! No offense but you nor your uncle sound like you have enough knowledge or experience to be messing with brakes based on your postings here.
If you really insist on fixing this problem yourself, go buy the Haynes repair manual for your truck and throughly read through the caliper, rotor and brake pad replacement sections. Then go back and start completely over. It sounds to me like the "rubber tubes" you mention were either not installed in the right place or are the wrong parts for your truck.
If this problem is something as simple as you used the wrong parts or installed something incorrectly, a shop usually wont charge too much to do a basic brake job and fix whatever little mistakes you may have made. Being at fault in a serious accident because you butchered your brake job will cost you alot more.....
