I can't seem to find the technical description in my service manual right now but this is from car and driver "There are safety improvements on the 2001 Ranger as well. Larger front rotors help stop two-wheel-drive models, and four-wheel ABS is now standard equipment across the line, acting in concert with electronic brake-force distribution, which provides dynamic pressure proportioning between the front and rear wheels."
