Enhance the braking performance of your HZJ80 and HDJ80 Toyota LandCruisers (ABS & non-ABS) with our top-tier Hydraulic Brake Booster Upgrade Kit. This kit features high-quality AC Delco hydraulic brake booster units sourced from the USA. Each unit is meticulously stripped down and machined for a perfect, direct bolt-in fit to your specific vehicle model.

Proven Reliability and Performance

This style of hydraulic unit has been a staple in the braking systems of Ford and Chevrolet heavy-duty vehicles for decades, offering unmatched reliability and performance.

Seamless Integration

Our hydraulic brake booster unit integrates smoothly with your existing power steering pump, maintaining the factory steering's operation and feel. By increasing the line pressure in the braking system from around 1,000 PSI to approximately 2,000 PSI, this upgrade significantly enhances braking efficiency. We recommend pairing it with ADR-approved stainless steel braided brake lines for optimal performance.
