currently running EBC HH pads

It's not "lacking" much in braking, the problem is no matter how many times I bleed (and others have tried) the brakes drag badly. At best you can spin the wheel on a stand 1.5 times, usually much less

 

Does your caliper look like this? You see how these pads are worn uneven? It's because the caliper is flexing because the slider bushings are worn (red circle). The same thing happens to SV calipers. I would disassemble the caliper, clean and polish the pistons, inspect the seals, make sure the slider bushings are not worn out, and clean the slider pins and make sure they are greased. Things that could cause dragging: stuck pistons, stuck slider, misalignment. Also, this may sound crazy but we had issues with piston drag using the small 15ml reservoir. When we installed a larger reservoir (30 or 45 ml cant remember) brake drag went away. The only thing I can think of is the extra volume of the reservoir assisted with the fluid retracting

 

Thanks Cop, I haven't noticed weird pad wear but I'll check. I've pumped the pistons as far out as possible to clean without completely removing them, probably need to take them all the way apart.
