Miscellaneous Brake Information
• The caliper from either Lincoln will bolt on to the Mustang spindle although the piston is 73mm in
diameter, so it would not be well suited for the recommended brake setups above. If this caliper is
used, a 1" master cylinder from a '93 Mustang Cobra, 84-86 Mustang SVO or Bendix # 12669,
although this is not an ideal setup.
• Thunderbird Super Coupe 5-lug rear brakes have a 4.25" bolt circle where as the Mustang 5-lug
bolt pattern uses a 4.5" bolt circle. The IRS hubs need to be drilled to the Mustang pattern. FFR
supplies new studs with the IRS kit.
• If you desire a dual master cylinder set up (having individual master cylinders for the front and
rear), the following information will help with those installations:
There are several different versions on the market. Dual master cylinder units usually use a
balance bar to proportion the amount of line pressures from the front to rear, so no
proportioning valve is necessary. We have used a unit from CNC brakes (part # 241). This
unit uses the Mustang bolt pattern, so it will simply bolt to the FFR foot box. Use the
following table to determine each master cylinder required.

• To calculate piston area, use the following equation: πr
• If using calipers with more than one piston, calculate the area for each piston, and then add the
areas together. If the caliper has pistons on both sides of the rotor, disregard one side.
