Hi Bud, I am sure it is because the servo'd brake version has dual circuit brakes and if one circuit packs up the brake lights do not work because of the lack of brake pressure on that circuit to work the switch, so the the other switch still works on the other circuit so no one smacks your rear end. (Nasty)If you are quick changing the swith you should not need to rebleed the brakes as it should not loose to much fluid, As for the ignition switch you have to remove the column and i seem to remember there are two grub screws holding the switch in place from the underside.
