Which master cylinder do i use for my 70 maverick? The car came with 4 drums but I have changed over to 4 disks, stock maverick fronts and lincoln versailles 9 inch rear with disks. Do I just use one for front disk and rear drum?
Use a master cylinder for car that came with 4 wheel disc. This way you get enough fluid to the rear calipers to puch the pistons out. It take more fluid to operate a caliper than a wheel cylinder. Master cylinders for disc brake cars usually have a larger bore diameter so they push more fluid towards the wheels as you press down the pedal. Try a versailles master cylinder or even a SN95 Mustang master cylinder.
I used a '91 Ranger/Explorer master cylinder with a 1" bore for my 4-disc setup. (They also have a 15/16" bore; I chose the bigger one because I have a booster.) It works great. You'll need to change out the flare nuts on your lines or get adapters because the fittings on the MC are metric.
