My rear brakes were defiantly binding as they stank and I can see score marks on these new discs. I took them apart yesterday and the sliders go in and out with no problems. The pads and shimms had no grease on them at all and the rear pads have about 2mm left. While I had the pads out and cleaned the shimms and surrounding areas both rear discs spin freely with only a slight scratching noise from the passanger side when a certain part of the disc goes around. Both Pistons were out about half inch and took quite a bit of force to get the back in. * should they go in easily? If the calipers are seezed I'd rather replace the whole assembly as I don't have the tools to replace the piston & seals. While getting the calipers changed I may as well change the brake lines for braided and the fluid at the same time. Is there a Honda specific brake fluid or is there better out there?
