Front Disc Brake Conversion Kit Ford Dana 44 1971-76 Bronco
Ft. Disc Brake Conversion Kit, Dana 44, 1971-76 Bronco
Our Price: $1,299.95

Are you tired of front brakes that fade after repeated use and go away completely when wet? If so, then this conversion kit is the one for you! We developed this kit for 1971-75 Broncos and F-150s with a ball joint Dana 44 front axles originally equipped with drum brakes; it will not fit Dana 30s.

Ours is the only kit on the market that allows you to walk into your local parts store with the simplicity of asking for replacement parts for a 1977 Ford Bronco! No trying to figure out what mix mash of parts the kit is made up of!

Our kit contains: steering knuckles which are drilled 3/4" straight through [this gives you the option of running heim steer or stock style tie rod over or under (using the included machined sleeves)]; caliper mounting brackets; rebuilt calipers; brake pads; brake hoses; hubs; rotors; brake hose bolts; and new spindles with the studs already pressed in.

While other kits used weaker, stamped steel caliper mounting brackets. We use nodular cast iron, which is actually heavier duty than Ford's original disc brakes! Proportioning valves and ball joints are sold separately below. You may need these when installing disc brakes. This kit will work only with the early style wheel to wheel tie rod original to 66-75 Broncos & 71-75 F150's, not inverted Y tie rods (as found stock on the 1976-77).

Power Brake Booster Kit, 1966-77 Early Classic Bronco
Power Brake Booster Kit, 1966-77 Bronco
Our Price: $435.95
Sale Price: $395.00
You save $40.95!

Specifically designed for your Early Bronco, our system brings the Bronco’s hydraulic brake system up to modern standards. This kit includes a brand new (not rebuilt) 8” dual diaphragm vacuum booster to provide better power brakes without having to modify the inner fender well. The bracket is designed like the OEM 1976-77 bracket for optimum reliability and linkage alignment. This system includes everything you need: a mounting bracket with all the hardware and the bell crank assembly; the brake booster; the correct master cylinder for your application; stainless braided hoses that go from the master cylinder to the proportioning valve; a master cylinder bleeder kit; a brake light warning wire; and a proportioning valve with bleeder protection tool. We’ve included everything you’ll need except the brake fluid! Our stainless braided hoses feature a smaller inner diameter over stock rubber hoses (creates more line pressure) and won’t swell. This means increased performance and improved brake feel. Plus, there is NO fabricating hard lines to make it all work!

For the best pedal feel and response, we offer two different master cylinders: one for drum/drum or disc/disc (driver side ports) and one for disc/drum (passenger side ports.) Specify which setup you have when ordering. If you upgrade to front/rear discs at any time, you can simply swap to the other master cylinder and proportioning valve (also sold separately for this reason.)

Stainless Braided Hoses, EB, Stock to 6" lift lines cables
Stainless Braided Hoses, EB, Stock to 6" lift
Our Price: $79.95

Lifted Broncos with lots of travel need longer brake lines to get the most from the suspension.These custom lines are stainless steel and DOT approved for street use as well as being longer to accommodate suspension travel. (Beware, many replacement lines are not DOT approved!) These lines won 't swell under pressure like rubber ones can.Smaller inside diameter increases pressure, which improves pedal feel and brake response. We have these specially made so you don't have to guess when it comes to the safety and soundness of your brakes. These are the lines that go to the differentials, not the caliper lines! Fits stock to 6" lifted 66*-77 Broncos. Note:*66 &67 may need to be adapted to fit front hose. Product appearance may vary from photograph but still fit and function as intended. more info
