Studebaker Master Cylinder Replacements For Turner Bracket

Note the bore sizes. A minimum of a 1.0" bore is required on all Stude cars, no matter what the brake configuration. A 1.0" bore will yield a 3-5" throw and good braking. A 1 1/8" bore will give a 2-4" throw and stiffer brakes.

Drum/Drum, Disk/drum and disk/disk systems ALL react differently, depending on the master cylinder and whether or not you use a booster. DO YOUR HOMEWORK on the hydraulics and have a safe trip.
