Street or Track Aluminum Master Cylinder Conversion Kit 

Aluminum bodied brake master cylinder with see through reservoir eliminates having to remove the cap (and introduce air and contaminants) to check fluid level.

  • Aluminum master cylinder with see through reservoir.

  • Master cylinder installation instructions & plumbing guide.


  • 1965-73 Mustangs and other Fords with the same bolt spacing (no modification to stock firewall needed). Body measures 7-11/16ths long.

Customer Reviews

Author: Mark Sellers (silverbluestang66@yahoo.com)
I have a 1966 Mustang that spends most of its time open tracking. I just replaced my old MC with this new 1" bore.
I have 12" discs up front and the stock 10" x 2" drums at the rear, this new MC works GREAT!! I have more adjustability due to the piston activating the brakes at the start of the stroke. Combined with my adjustable rod, I can fine tune the height of the brake pedal to the height of the gas pedal. Makes heel & toe downshifts much easier.

Great product!!
