Ok, so after yesterday's 'cross race, I needed to clean all the mud and grit from my brakes. So I disassembled them as far as I could by removing the brake from the post and the pads from the brake. Cleaned that mess up, so far so good.
But, there's still grit inside the pivoting point of the actual brake itself. Not sure of the technical part name, but there are two pieces of hardware that rotate inside the brake pivot point. One is the bracket that holds the adjustment screw, and the other holds the spring.
I'd like to be able to take those hardware pieces apart to clean and re-grease. It looks like maybe there's a retaining clip deep inside the pivot that I can't access. Possibly a special tool is needed OR the brake just wasn't designed to be maintained at that level.
Anyway, any thoughts or suggestions are appreciated.
