good evening , i have a 69 mercury cougar with disk brakes in the front and drum brakes in the rear . I would like to convert the rear to disk as well . I am good with a wrench but i have never done a brake conversion before . I did some searching on this site and a few links mention that he brake pedal needs to be replaced on some conversions. Would that be the case for me as well seeing as i already have disk in the front. What i would like to know is whats the conversion kit most use? Also is there any videos that any of you guys recommend on doing this. Finally how straight forward of a job is this ...definitely don't want to open a can of worms . The main reason i want to do the conversion is because i am tired of the drum cylinders in the rear wheels leaking after a year or so . Thanks in advance
