Hydraulic Brake Booster Upgrade Kit to suit VDJ76, 78, 79 Toyota LandCruisers – 08/2019 on (ABS)

The Marks 4WD kit utilises the AC Delco hydraulic brake booster units sourced from AC Delco in the USA. Our workshop then completely strips down and machines each unit for a direct bolt-in fit to the particular vehicle model.

This style of hydraulic unit has been used in braking systems for decades in most Ford and Chevrolet heavy-duty vehicles where they are well proven for reliability and performance.

The hydraulic brake booster unit connects in line with your existing power steering pump without affecting the operation or feel of the factory steering.

As the line pressure in the braking system is increased when using the hydraulic unit from around 1,000 PSI up to around 2,000 PSI, we recommend replacing your old factory rubber brake lines with our Marks 4WD ADR approved stainless steel braided brake lines.

Our engineers have fully tested the braking system on the vehicles to ensure they meet current Australian vehicle standards enabling us to provide the necessary documentation to assist with having the unit approved on your 4WD.

The test results braking from 100km/h demonstrates why the upgrade is an important addition to your vehicle. (Note: Results will vary with tyre dimensions, vehicle model and modifications)
