Hydraulic Brake Booster Upgrade Kit to suit GU / Y61 Nissan Patrol (ABS) with a Duramax V8 Diesel engine
The Marks 4WD hydro brake upgrade 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 it is 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 vehicles’ braking systems to ensure they meet current Australian vehicle standards. This enables us to provide the necessary documentation to assist with having the unit approved for your 4WD.
