Is the master higher or lower than any of the calipers? If it's lower, you need to bleed backwards, if it's higher, just fill the master, crack the bleeders, and sit for about 5 minutes, and it should be OK, you may have to take the front's off, and lay them down. I mounted my reservoir on the panel above the motorplate, and hosed down to the master. Where my reservoir is, it is higher than any of the calipers! Bob
