Grow old disgracfully
Check that the piston in the caliper is not siesed & that caliper can slide on the mounting bolt failing that is it the corect M/Clyd. for the caliper

In my opinion the pads from mikes seem to get a little better with use. I'm currently facing a similar problem with my bobber. I am running a Harley rear master cylinder with dot 5 brake fluid and a stock xs caliper and rotor and my rears suck! But the are getting better have about 100 or so miles on them. Make sure the brakes are bleed well. Best of luck I will keep you posted if I figure anything out

Too small of a hose would be A possibility. That's a good point! Anybody else experiencing these problems?

No mention of a front brake?
, i would rather have a front brake only than a rear brake only. Rear brakes make a nasty noise when applied hard. Thats the sound of hitting that stopped vehicle in front of you. Keep it on one wheel. Mitch

I had stock OEM calipers on my 78SE, and the braking was acceptable. Through the years I've had a few encounters with things jumping out in front of me (such as deer), which required emergency application of both brakes. I decided I didn't want to have a collision with any forest critters, so I now use Brembo 4 piston calipers on front and rear. The braking power is much increased as compared to stock. Really big safety factor!

Its the caps lock that is fucking your build!!!!!
I don't know if this is your problem or not but I once found a brand new brake line fitting with casting flash (trash) that was blocking most of the opening. Took me weeks to figure it out and about 3 minutes with a tiny file to fix.
Since then I always look for casting flash in new parts before I put them on.
