I have front and rear chevy disks. With the full float conversion they work amazing. I did it because at the time they were really cheap to do. Rock auto had calipers for 12 bucks with pads. Thats the only reason I did it. Now I have power 4 wheel disk brakes. Love them, but still don't have a good E brake. If I had the real rear 11" drums with the e brake stuff, I would install them.
