funny brakes after 4wd swap

[Jimbo92]

I just recently installed a 4wd front axle in my 92 explorer. my 92 was not equiped with front abs but it apeared that the new 4wd front was. will this affect my braking. The pedal goes pretty far to the floor but idk if i need to blead them or if it is b/c of the axle.

Sounds like you got air in there. Bleed them the abs sensors won't make any difference to the hardness of the peddle.
