For those on a tight budget - I put a set of BrakeBest Select semi-metallic pads and BrakeBest rotors from O'Reilly's on my '94 Explorer last August or Sept. I like them so much I put the equivalent parts on my Sport Trac a couple of weeks ago. $33.99 for the pads, $46.99 for each rotor
Tip concerning rotors - check both sides of each rotor! The outer sides of both rotors on my Sport Trac looked and felt fine. The back sides had chunks missing like the surface had flaked off in places. The inner pads were worn down more than the outer ones, too.
