If the bleeder is on the bottom, u have the wrong caliper on there!! What yr Ex do u have? I recently did my rears and the computer at advance auto parts pulled up the wrong parts. I have an early build 2000 and the calipers r mounted to the left of the rotor on both sides. Which means it is actually the same caliper for each side. The computer pulled up different part numbers bc ford changed the calipers mid-year and r mounted toward the rear on both sides. Hope this helps!!
