First the actuating arm slipped off the little push-rod on the rear, rendering the rear brake useless. Got that fixed, but noticed that the front was requiring constant adjustment on the barrel. Trying to stay on top of that, then this morning the rear brake disappeared completely. I stopped in the rain, late for work, thinking that the arm had slipped off again. When I watched the caliper while squeezing the brake, I saw little bubbles appearing from the top of the reservoir. What the heck??? Continued my commute with front brakes only, and by the time I got to the office the front brake was barely working again and hardly slowing the bike down. No brakes is OK on my fixed gear, not on my rain bike!

Sketch-balls! It is frustrating. I had not done any research until now, but this thread explains a few things. Guess I will be calling TRP...
