Only put some on the pad backs and top off pistons, as the pads wear the pistons will come away from the seals so shouldn't touch the seals.
The pistons were dry before hand is this normal?
Bike is a 53 plate and done 4000m's
After a ride they feel much better no pad dragging as the pistons return

but it was freezing!!!
