Fat Fender Garage is pleased to offer our Wilwood Master Cylinder kit for your 1967-1979 Ford 1/2 ton trucks as well as 78/79 Broncos. We use Wilwood brake solutions on our project trucks because it’s the best and we’re now offering this kit for the DIY guys.

Have you upgraded to disk brakes up front? Disks out back? Have you installed larger wheels and tires? Coyote swapped your truck or upgraded your power-plant? Increased your horsepower and finding it harder to stop your truck? Allow us to present you with our new bolt-in solution!



  • Wilwood tandem master cylinder with a 1″ bore. Machined from high-pressure die castings, each master cylinder weighs only 3lbs, a 75% weight savings over most cast iron OE type master cylinders.
  • 8″ Tuff Stuff dual diaphragm booster that provides room for your Coyote motor. It will also clean up your firewall if you are upgrading from the original stock booster on your truck.
  • Fat Fender Garage custom designed push-rod that makes this kit work with your stock brake pedal assembly.
  • Fat Fender Garage firewall plate and grommet to seal off the opening.
  • Fat Fender Garage mounting brackets. Many of you told us that you needed mounting brackets because your truck did not come with them, or they are missing. We now include them with our kit.

Great Parts! Specfic for FFG and Porter built frames.

Good quality parts, just they won't work with a QA-1 suspension upgrade with a stock frame. Booster sits on top of last ignition coil drivers side. Would have to remove vacuum booster in order to change plugs or ignition coil. This is if you are installing a Coyote 5.0 engine.

Lacking instructions

There were instructions on how to bench bleed the master cylinder and proportional valve instructions, but there weren’t any assembly instructions for the brackets to the fire wall and to the master cylinder. Or instructions how to adjust and torque the master cylinder clearance. I had to search the internet to find pictures of the assembly. Also the brackets were in a plastic bag and rusty. I also had to grind the lower angle brackets to get them to fit. I have wanted a Wilwood master cylinder for years, but I’m very disappointed with the rusty parts and lacking instructions. Systems as important as brakes should not be lacking instructions. However, I’m very impressed with FFG and the fast delivery of the kit. Jim Bowman, Indianapolis, IN.
