March 4th – The front brake was feeling funny again, it had some initial resistance – like a click – when applied. I’d had it before but couldn’t recall the cause.
Turned out I discovered it riding to work when I lost braking power on the same brake. The pads were so worn, the return leaf spring was being pushed out of place by the disc surface.causing the click.
The pistons were opened back out with a wedge tool for the purpose and new pads dropped in. Braking harmony restored!
