The R80G/S so-called front brake... possible fixes?

[Solo Lobo]

The 4 pot K caliper mounting lugs have to be machined to 10.5 mm -

fairly straightforward job.

After repeated measures, I see that you are correct. If I machine the lower caliper ear to 10.5mm, it will work with the lower fork leg boss, but I will still need to make an adapter as the upper caliper mount doesn't allign with the upper fork leg boss....
