Description
Our Power Brake Booster Kit is the ideal solution for modernizing your Bronco’s hydraulic brake system. This comprehensive package provides everything necessary for an effective installation and improved stopping power. Key components include:
– New 8″ dual-diaphragm vacuum booster
– OEM-style mounting bracket for optimal reliability and linkage alignment
– Complete mounting hardware and bell crank assembly
– Aluminum master cylinder tailored to your specific application
– American-made DOT tested stainless braided hoses for master cylinder to proportioning valve connection
– Master cylinder bleeder kit
– Brake light warning wire
– Proportioning valve with integrated bleeder protection tool
The upgraded stainless braided hoses offer superior performance, with reduced inner diameter compared to stock rubber hoses, resulting in increased line pressure and improved brake feel. Importantly, no fabrication of hard lines is required for installation, facilitating a straightforward upgrade.
For optimal pedal feel and response, you can choose from two distinctly designed master cylinders:
– Drum/Drum or Disc/Disc (driver side ports)
– Disc/Drum (passenger side ports)
Ensure that you specify your current setup during ordering. If you decide to upgrade to a front/rear disc configuration at any point, a swap to the alternate master cylinder and proportioning valve (sold separately) is a seamless solution.

This kit is awesome, comes with everything you need to install a booster and is a must have if you plan to go up in tire size.

Super easy install and definitely one of the best upgrades or updates one can make to their early Bronco. Different kits for different applications make this one a “no brainer”. Because stopping is cool! Everything included for simple install. Definitely recommend this kit.

I was a little intimidated to take the step of installing booster brakes on my 71. I watched the videos and all in all it was fairly easy, This is one of the best upgrades Ive made yet.
