Countless old Jeeps have the factory brake master cylinder mounted to the frame, and while that is not necessarily the ideal placement, many Jeep nuts want to keep the factory through-the-floor-pedals in place. Several years back we mounted a larger-than-stock master cylinder to the inside of our Willys’ driver-side framerail. Years of wheeling and driving the old Jeep caused the master cylinder to start acting funny. We made this bracket out of some 3⁄16-inch plate. A little time with an 11⁄2-inch hole saw, a unibit, a chop saw, and our reliable Hobart 175 MIG welder will ensure the Wilwood master cylinder will now have a secure, flex-free, home in front of the brake pedal on the framerail.
