Landcruiser SAHR Brake systems

AUSCO and ABT SIBS brakes are types of sealed, wet disc brakes designed for extreme applications like mining, heavy industry, and rugged terrain. While they are not standard on road-going Toyota LandCruisers, they are often retrofitted to LandCruiser 70 Series and similar models for underground mining or heavy-duty off-road applications.

Here's a breakdown of both systems:

🔧 1. AUSCO Brakes (Wet Disc Brakes)

• AUSCO is a manufacturer known for sealed wet disc braking systems.

• Commonly used on modified LandCruisers for mining and industrial use.

Key Features:

• Sealed system – protects from dust, water, and debris, ideal for mining or muddy environments.

• Multiple oil-cooled discs inside a sealed housing.

• Long lifespan, low maintenance, and high performance in dirty or wet conditions.

• Typically used in underground mining-spec LandCruisers.

• Enhanced park brake capability for steep underground ramps.

🛠 2. ABT SIBS (Sealed Integrated Braking System)

• ABT (Australian Brake Technology) developed the SIBS specifically for mining and off-road fleet safety.

• Integrated into the wheel hub, combining service and park brake functions in one sealed unit.

Key Features:

• Oil-cooled, sealed multi-disc design.

• Provides service braking, emergency, and park brake functions in a single unit.

• Extremely durable with low maintenance.

• Built to withstand harsh mining environments.

• Often includes fail-safe and emergency brake activation systems.

🧰 Why Use These Brakes on a LandCruiser?

• OEM brakes on LandCruisers are not designed for continuous braking on steep declines or dusty, wet environments.

• Mining environments require fail-safe braking systems that operate in case of hydraulic failure.

• AUSCO or ABT SIBS provide extended durability and increased braking reliability.

🚙 Common Applications:

• Toyota LandCruiser 70 Series (e.g., 76, 78, 79 models) used in:

  • Underground mining

  • Remote exploration

  • Heavy off-road use
