I'm rebuilding the rear M/C and brake caliper on the 00 426 YZF. It was locking up after riding for a while. Everything is apart and I'm ready to start reassembling with the new parts. It's going back together with new EBC red (x) brake pads. The EBC package says "do not fit original shim and insulator". Is that correct? So the backside of the pads contact the caliper body and piston directly with nothing in between?
