Disc brake kit off of my Tera60....has EBC rotors and green stuff pads with about 100 miles on them. They are ford 8.8 disc brakes with the ebrake inside the rotor. Teraflex's site says their Tera60 axles use the large ford 9" housing ends, so they say they will fit 9" and 8.8" housings?.... $399 new from teraflex with standard rotors/pads. EBC rotors; $170 pair (summit), and pads; $65 set (summit). Pads and rotors are haven't been on long.
