Another somewhat unexpected benefit was the huge increase in factory braking between a ’94 1⁄2-ton, and a ’103⁄4-ton truck. Not only are the rotors on the new axles bigger, but both front and rear brake calipers are dual-piston units with larger pads providing more stopping force. This will make a huge difference in stopping a heavy trailer. Shown here from top to bottom are the new front caliper, the ’94 front single-piston caliper, and the new rear caliper. Note the rear caliper is the same size as the old front caliper, and it is a dual-piston unit to boot.
