well these are working perfectly now got some new elastomers in then i noticed the steerer was loose :? the 2 bolts in the crown were only touching the steerer as there was 2 broken bolts stuck in there already :evil:
so i drilled them out and tapped the holes and fitted 2 new bolts
the caliper was blead and works fine now too so just a set of bearings to buy and fit and i can use them
