Front brake question
Trigger:
There is a bush in the alloy arm that can be replaced to match the pin.
Another trick is loosen off the two top bolts and squeeze it down with a G clamp then, tighten the two top bolts.

Thanks Simon, that thread is really useful. If necessary, I'll try the shim solution.
If that fails it'll have to be a new bush in the arm.

You know i had forgotten about that bulletin! Old age or Guiness , not sure which!

...for the first time in a year or so I had 2 pints of Guinness for lunch. Dear god I’d forgotten how good it is...

Tayside... you cost me a couple of hours work today!
Anyways, was changing the K2’s pads over to semi-sintered, and took a harder look at the caliper ‘nod’... which in truth was now concerning. The ‘nod’ was radial, and all due the pin slop in the top / bottom carrier.
Engineers look away now, but I fixed it by using lengths of feeler gauge cut to match the pin circumference and inserted into the carrier. To take the split pin I simply used a punch once the holes were lined up...
FYI the feeler gauge thicknesses needed were 9 & 10 thous; implying the carrier holes are about 20 thou oversized. (The pin is new). (Odd jobs shim-washers went back in)
There is no play in the caliper now, and I have bought myself a bit of time whilst I either source a new carrier or quality engineering to fabricate an insert.
Cheers,
Simon
