Hydroboost Brake Kits & Components
Upgrade braking performance with hydroboost brake systems designed for off-road vehicles, custom builds, and high-demand braking applications. Wide Open Design hydroboost kits use hydraulic power steering pressure to provide brake assist, delivering strong braking force without relying on engine vacuum.
Hydroboost is especially useful on rock crawlers, buggies, engine swaps, and vehicles with large tires where consistent brake assist and compact packaging matter. Choose from systems configured with OE-style, Wilwood, or compact Wilwood master cylinders, along with supporting components to complete the installation.
| Configuration | Best For | Builder Consideration |
|---|---|---|
| OE Master Cylinder | Straightforward builds and common replacement parts | Traditional master-cylinder configuration |
| Wilwood Master Cylinder | Performance-oriented custom builds | More flexibility when designing the braking system |
| Wilwood Compact Master Cylinder | Tight chassis and engine-bay packaging | Reduced packaging footprint for custom builds |
