Several years ago, my grandson, who was stationed at camp LeJeune at the time, was helping his friend repair the brakes on his truck, a Dodge Ram, IIRC. They had used up a huge amount of brake fluid bleeding the system, and still had very marginal braking. He called me to ask for some advice. One of the first questions I asked was about the location of the bleeder screws on the front calipers. It turned out they had installed the new calipers upside down- - - - -left caliper on the right side, etc. and the bleeders were on the bottom instead of the top. They swapped them left to right and solved the problem!
