This is a compilation kit-- Our proven front disc brake conversion kit, power brake booster kit, and all the other items you need to complete the install! Even an option to add rear discs at the same time! When it comes to strength and performance, we have you covered. The knuckles are stronger than the factory, don't kick in against the wheel like the '76-'77 knuckles, and the tie rod ends come pre-drilled for heim steer.
For those wanting to run OEM steering, we include adapter bushings. This kit is designed for all Ford open knuckle Drum brake Dana 44's. It is a whopper!!
The axle parts included in this kit are a Ford-based design. You can walk into any auto parts store and ask for 1976-'77 Ford Bronco disc brake parts when it's time to replace your wear items* or call us. The booster bracket, booster, master cylinder, and master cylinder to proportioning valve brake lines are aftermarket only. Please call us for replacements on those.

Great kit as alternative to the wilwood. Disc brakes a necessity for any lifted bronco and a great idea for any stock one. Kit comes with all parts to install the setup.
5/5 highly recommend.

Fantastic kit and worth every penny. The knuckles are quality and it’s nice that it’s Ford parts. Everything you need is included. Just buy it.

I have a 1973 Bronco with 1” suspension lift. The main reason I bought this kit was for the knuckles. You won’t be disappointed with these. Super beefy and appear well made. Also, I did not run into any issues with my tie rod contacting the lower track bar stud/castle nut. It’s close, but I think I’m good to go. Great upgrade!

the answer Don’t. when I decided to rebuild my axle and upgrade from the old drums I want something I can replace and fix when I have to and not worry about if its already worn out or has a defect I cant see under a bunch of rust. these are new, clean and everything fits like it should after a few hours I have both sides on and looks great.

The braking while under control is amazing. The fact that it is all Ford parts makes it perfect.
Tom Kennedy –
All parts received in a timely manner. Very happy with the heavier materials. Far better than the Chevy setups. Instructions are straight forward and easy to use.

Dealing with the staff at Duff was a great experience. There was a delay in getting the kit delivered put it was because of their strict quality control standards! Knuckle didn’t meet those standards and they delayed shipping until issue was corrected. I appreciate this quality for I want to offer my customers the best as well. Every thing fit properly, braided lines to the proportioning valve look sharp and eased the install. Functions very well and have great stopping power!
