Do you feel the lever is spongy for the initial pull or only the second or third application? Possibly a bad wheel bearing or sticking rotor button making the rotor push the pads into the caliper.
The first pull they work great. After that they go spongy.
Gonna try tapping on the bars a little while bleeding the next time to see if I can get any more air to go up to the mc. I've been bleeding to calipers first then moving to the mc.
