Brake questions

Something important to note that hasn't been brought up yet. If you have a 4 wheel drum '70 Dart you also have the small bolt pattern, 5x4". If you want to keep that bolt pattern, you have fewer options for front disk brakes. If you're going to upgrade to the large bolt pattern (5x4.5"), then you'll also need to convert the rear brakes and axles.

There are a couple of disk kits out there that allow you to keep the SBP, but even some of those kits won't work with the original small bolt pattern drum brake rims (the center register for those wheels is too small for some kits). So even if you use a SBP disk brake kit you may have to buy new wheels.

It also makes a difference what drum brakes you have now, the 9" drums and 10" drums have different spindles. So depending on which spindle you have your options will be a little different (if you keep your current spindles).

There are a ton of threads on FABO about disk brake conversions and the different kits available. First you should decide if you want to keep the SBP or upgrade to LBP, then do a search on disk brake conversions.
