15°C, light SW breeze, strong sun & dry.

First ride after breaking a rib or two. On the last DofE, I tripped over a black guy line in fading light.
Strange mechanical problem; I had no front brake. I thought at first the long stopping distance weas due to oil on the brake disc, I’d given the bike a minor service earlier. However, on closer inspectiong, I’d adjusted the front caliper as far as it would go, and the pads still didn’t touch the disc. Then, I took the wheel out. Now I could see it, one of the pads was missing, and the other – very thin. There is quite a puzzle.
Now I think, the pads had become so thin that one had fallen out during a previous service (probably on re-assembly), ort maybe when putting the bike in the car.
