Normally the question is what will fit on Mavericks from other cars. This is the opposite. Will front disc brakes from a '75 Maverick fit on a '66 Falcon?
disc brakes Yes, and it has to be done as a package setup. Spindles, prop valve, outer tie rod ends, and master cylinder. Drum brake MC and prop valves are very different. It's an easy swap. Did it on my son's 72 grabber.
I am running a drum brake master cylinder and proportioning valve on my '72. I have exactly 9,665 miles on the car since I rebuilt the front end and installed the disc brakes. The car is a daily driver, sees sometimes quick stops in rain on a regular basis, and my brother drove it over 100 miles in snow a few months ago. No problems what so ever, the car stops excellent. My dad ran a manual drum master cylinder and proportioning valve on his '71 Comet also, with 4 wheel disc brakes. The car ran low 12's in the quarter mile and was driven on the street regularly (more then once in down poor rain) without problems.
