Took off early sunday mornig from south of Boston to hit the white mountains up in NH. We picked up a couple of friend that had never been up ther before and headed off. coming out of the tunnel in town the brake light came on and i lost lots of brake presure. We stoped to take a look and found a small leek in the metal line tha runs along the rear dif. topped off the brake fluid and headed off. Man do the turists love that old man in the mountain stuff. Made it there and back ok and everybody had a good day.
