Brakes suck

Hello, I went riding my dual sport bike today. I did not stay out very long because my brakes sucked bad. I pulled the bike back in the garage to look it over good. I found the brake pads still have plenty of meat left, but I found air in the rear brake line and the front brake line was contaminated. So I bleed both the front and the rear brake lines and the brakes work much better now. I also noticed that my bike has a lot of bolts that are too short. So I made several trips to ace hardware to buy bolts that where the proper length. I think I will start putting lock tight on all the bolts because, I found some bolts where loose.
