Thanks for the feedback. Mintex brake lubricant was used.(ceratec)
I've ordered some mintex rubber anti squeal shims & some new spring clips. But can not source any pins.
Mintex tell me that their FIT shims are not required for the MLB52 pads.
Ceratec, is supposed to be better than old fashioned copperslip & is safe on brake rubber, like dust seals on rear cyls
Personally I prefer genuine Ferodo pads, very good 'fit' and never had issues with squeal
