After my off a couple of weeks ago, I still haven't got a brake pedal found. I took the bike in to have a new front tyre put on a few days ago and when I picked it up, I had a brake!
Hole drilled in the lever and the bolt shoved through with a nut each side of the lever and what looks like a rubber sleeve around the bolt.
Obviously not a permenant fix, but it's good 'til I find a cheap pedal.
