I'm trying to fit Brembo HPK supersport discs (5.5mm thickness) to my S1000RR. Being a standard base model bike, it previously had the thinner standard discs.
I'm having trouble getting enough spread in the calliper pistons with new pads to fit the new discs in. With both callipers off the bike, If i spread one calliper out enough, it's pushes the pistons in the other one closed. If i have one fitted on the bike.. i can't spread the pistons far enough in the calliper that's not fitted.
Do i need to let some pressure out of the system to allow enough clearance, what am i missing here?
