The BEST Hydroboost Power Brake System on the Market.

Our Price:


NEW! WILD HORSES new MOAB Hydroboost power brake system takes the early Bronco Hydroboost kit to the ultimate level. We left no stone unturned in the design of this system. It can be used as a stand-alone kit or in conjunction with any of the front and rear drum or disc brake options we offer. High-end precision components make up the MOAB starting with the billet firewall mounting bracket set (zero fender modifications required) followed by a brand new booster. Next we attach a new Wilwood Tandem Aluminum master cylinder. Stainless steel hard lines and a prop valve drop bracket tie the adjustable proportioning valve into the side of the master cylinder. From there we use stainless steel braided, precision-made, flexible hoses which go into our custom stainless steel frame bracket. The frame bracket holds the flexible hoses in the perfect location to allow installation into the existing stock hard lines on the frame with no adapters.

Choose 66 / 76-77 or 67-75 Bronco
If you have a 1966 Bronco with the original single reservoir master cylinder or the 1976-1977 you will need some additional stainless hard lines. Be sure to choose the correct year for your application.

After installing a Blueprint 408 I realized this new engine does not make enough vacuum to run my brake booster. After talking to several friends the Hyroboost was the only way to go! I ordered it. Installed it per the directions and WOW! I can darn near stand my Bronco on its nose! Super awesome product from the best guys in the business for bronco parts!

I struggled to get even marginal braking with 32s and a vacuum booster. The brakes were weak even after going to disks on all four corners. It always felt like I had a little air in the lines even though I had bled them over and over. This kit CHANGED EVERYTHING. It is a night and day difference. The install was pretty straight forward, It took me an afternoon lazy wrenching to get it put on. Now my 74 bronco stops so well that the brakes on my brand new vehicles pale in comparison.

this thing is awsome

Just finished installing this on my 76 Bronco. Directions were well done easy to follow. Good pictures to help answer questions. I have had poor breaking with my last 2 engines due to high compression. This system works great. Took me about 6 hours total to install. Needed to make a small adjustment to the proportioning valve and you need to make sure you get all the air from the power steering system or you will get a bad pedal feel while the motor is running. Every part fit great the system was well thought out. I would buy this again in a second.
