So, you're using a single six piston caliper, and one rotor, with the stock 11/16 master cylinder? I thought that we "HAD" to use the 5/8? If this is true, it sure would save some money not having to buy a new master cylinder.

I'm running a single Jaybrake 6 piston caliper with the stock rotor and master cylinder. Works great. I know others will disagree with me, but I really don't feel like I lost any braking power over the stock calipers.

Im running dual pm 6 pistons on my street glide. After about 1 quart of brake fluid,approx.60 bleeds with and without vac bleeder,I put my stocks back on,and went to pm. Found out they changed o-ring manufact. and put to thick of o-rings in! It took about 4 pumps to get brakes! They put new o-rings in,and now they work great! One suggestion to pm,use a larger bleeder screw,more like factory ones,those pm units strip easy!

That surprises me. If your braking is greatly reduced, why are you continuing to use it?

I am running a single six piston PM caliper on the front of my bike and a 4 piston PM on the rear. They are chrome (ooohhh). I bought the bike used with them on but am quite happy with them as I have compared them to my wife's stockers on her 05 sporty and there is no comparison. When I ride the sportster I have to grab the brakes a couple of minutes before I want to stop it seems. The PM's provide excellent stopping power on my fatboy, even with the extreme weight of the bike. I would highly recommend this mod. I find brakes to be on of the most important items on a bike along with the tires. In fact the PM's are the thing that really swayed me to buy the bike I have.
