Marks 4WD Hydraulic Brake Booster Upgrade - Toyota LandCruiser 70 Series (ABS Models)

Description

Ultimate Stopping Power. 40m Shorter Braking. Engineered Reliability.

Transform the braking performance of your VDJ 70 Series with the Marks 4WD Hydro Brake Upgrade. Designed to replace the inadequate factory vacuum booster, this kit utilizes proven AC Delco hydraulic units—the same technology used in heavy-duty US trucks for decades. By doubling your braking line pressure from 1,000 PSI to 2,000 PSI, this system delivers a more responsive pedal and drastic reductions in stopping distances, especially for heavy-duty touring and GVM-upgraded vehicles.

The Performance Difference

In real-world testing on a 3,780kg LandCruiser 79 Series Dual Cab (braking from 100km/h):

• Standard Factory Vacuum: 98 Metres
• Marks 4WD Hydraulic Booster: 58 Metres

That is a 40-metre saving in emergency stopping distance.

Key Advantages

• Reduced Pedal Effort: Easier, more comfortable braking under all conditions.
• Increased Stopping Power: Safely manage heavy loads, larger tires, and towing.
• Direct Bolt-In Fit: Each AC Delco unit is precision-machined by Marks 4WD for your specific model.
• Factory Feel: Integrates seamlessly with your existing power steering pump without affecting steering feel or operation.
• Engineered to Comply: Fully tested to meet VSB14/ADR standards with documentation provided for certification.

Kit Includes

• Genuine AC Delco Hydroboost unit (Modified for direct fit).
• High-pressure hydraulic hoses and all required hose clamps.
• Full hardware kit including bolts and washers.

Important Vehicle Requirements

• Brake Lines: Because line pressure increases to 2,000 PSI, we highly recommend upgrading to Marks 4WD ADR-approved stainless steel braided brake lines to replace old factory rubber hoses.
