Hey guys, Sorry for so many posts and Q's... I'm thirting for MTB tech, and you guys are a watering hole of good info. Here is my deal. On my Giant Rincon it's got discs F&R. Last night I played around with them and clenaed the pads with brake parts cleaner, adjusted the cable and such. While there I noticed two things. 1- the lever arm has a very very small allen set screw that was kinda lose on the F&R. So I snugged that up. 2- the larger outside allen that looks to hold the lever arm on was lose also F&R. so I snugged these both up on the F&R. I can't believe how much better my brakes are. I've been complaining about the brakes on this bike since new. The rear brake would never lock the tire up which I found odd. But after making thos adjustments feels like I put a set of Bremebo's on it!! 10x's better. can't believe it. But I also noticed on the back side of the calipers there is one larger allen deal. Seems to adjust the inside brake pad or something. You can't tighten it up bc it locks up the pad. How/what is this adjustment?
