I just took my rear tire off of my mountain bike that has hydraulic disc brakes (elixer5). When I put the wheel back on and started pedaling it made a clicking sound.
At first I thought it was the spokes rubbing up against something (that's what it sounded like, some metal sound). I took the tire off again and took a good look at the disc brake pads, I saw a skinny metal "r" shaped thingy leaning out in the slot where the disc would fit.
Is this where the clicking is coming from and if so how do I fix it? Please ask for any more information I couldn't think of for more clarification.
