I just installed a ford 8.8 with disc brakes out of a 98 explorer
the question I have is due you need to change anything with the
master cylinder for the disc brake conversion, I have been getting
a scraping sound sometimes, it sounds like the pads rubbing on
the rotors. any help would be great.
thanks.

Sounds like you need to remove the residual pressure valve for the old drums. It's located in the master cylinder in the hole that the rear line screws into. It keeps 2-3psi in the line going to the rear.
