Who has a KH sbp "non-power" disc in front
I have nonpower 4-piston KH discs on one A-body currently and on several A-bodies over the years. Your choice of master cylinder will have a big effect on pedal travel and feel. My preference is for a 1" bore, but these are getting hard to find since they were used only through 1970. '71-'72 got 1-1/32" for power and manual. Starting in 1973, options were 15/16" (with power booster) or 1-1/32" (without). The larger the bore, the shorter the pedal travel but the "harder" will be the pedal. The smaller the bore, the "easier" will be the pedal but the longer the pedal travel. Make sure to use a new (not "remanufactured" junk) master cylinder such as Raybestos MC36426, and choose your brake pads carefully; if the pad compound you use is too hard (semi-metallic, etc.) you'll have a very hard pedal. I like regular organic pads on this system.
