Hey gang. Quick question for you guys. I recently changed my back rotor and brake pads. Everything went smooth, got it all installed, bike tire on and when I went to ride it, that thing was all over the road. Back in floating everywhere. It was next to impossible to hold a line on the road. From what I can tell, the axle is in straight, and belt tension is where it should be 3/8 to 1/2 play with a 10lb tug! It wasnt like this before and its like I am fighting it the whole time I ride! I did check my air pressure in my back tire and it is really low. 13lbs of pressure. Could this be the problem. Its pouring down rain right now and supposed to snow tomorrow so I havent tried increasing the air pressure yet! Any other ideas why this thing is all over the road? Thanks guys in advance for all your help. These are very imformative forums! Shady1324!!
