Info

Dual feed master cylinder with 2 bolt flange style mount. Use with Speedway brake pedal assemblies. This cylinder is similar to those used on mid-70's Fords (Mustang, Fairlane/LTD, etc. with disc front/drum rear).

  • Mounting Bolt Holes:  3/8" or 10mm 
  • 7 1/4" long without the pushrod, add 2" for the pushrod
  • 3" wide from the outside of the reservoir to the edge of the outlets
  • Mounting flange is 4" wide
  • Master cylinder is also 3-7/16" tall without a cap
  • Included push rod is threaded 3/8"-24 (fine thread).
  • If you need a yoke for the pedal hook-up, use this Forged Steel Yoke.
  • Push rod boot included.

Uses 3/8"-24 female inverted flare outlets. If plumbing with AN 3 lines, you will need two each of these AN to IFM Adapters.

Notes

  1. Tech Tip: The bigger the master cylinder is, the more fluid you get, but you'll have less pressure at the caliper.
  2. There is no longer a loop on the end of the push rod for this master cylinder. It is now threaded 3/8"-24 (fine) male. If you need a yoke for pedal hook-up, use 910-02973.
Some parts are not legal for use in California or other states with similar laws/regulations
