The ultimate failsafe brakes for underground mining vehicles.

ABT Failsafe Brakes Benefits

Improved safety

The extremely low wear rate of the ABT Failsafe brakes means the service and park brakes perform properly EVERY time. The ‘spring applied hydraulic release’ ensures that the park brake is always FULLY applied, eliminating the potential for partial application of the park brake, a significant risk for ‘uncontrolled vehicle movements’. The park brake is electronically interlocked to ensure the park brake is applied every time the engine is turned off or a door is opened. If there is a component failure in the brake system, the park brake is AUTOMATICALLY and FULLY applied, completely eliminating vehicle runaway.

Low maintenance

Minimal maintenance is required as all key brake system components are now enclosed and protected in an oil-filled housing. The REDUCTION in maintenance costs and vehicle downtime quickly absorbs the initial capital outlay.


As the brake caliper, rotor and brake pads are fully sealed in an oil-filled housing, ABT Failsafe brakes component temperatures are reduced and completely PROTECTED from contamination. This results in super reliable service and park brakes as there is no deterioration of the critical brake system components. And as the park brake is applied fully every time through the ‘spring applied hydraulic release’, vehicles are RELIABLY restrained every time, eliminating the need for vehicle chocking.

Environmentally sound

As ABT Failsafe brakes are fully SEALED, airborne particle emissions are totally eliminated, delivering occupational health and safety benefits to personnel and broad environmental benefits.

Wheel End Assembly

  • A fully enclosed wet brake assembly that replaces the standard brake rotor (or drum) and brake caliper assembly
  • Can be fitted to the rear brakes only or to all four wheel ends
  • Includes a ‘spring applied hydraulic release’ system. Hydraulic pressure is used to overcome the force of disc springs contained within the rear wheel end brake assembly. When the hydraulic pressure is released, the park brake applies automatically.

Emma Pump Module

  • An electrically operated hydraulic pump module that is used to pressurize the park brake system that is integrated into the rear wheel end brakes. The hydraulic pressure is used to release the park brake.

ABT Control Box

  • A dash mounted control box used to control the application of the park brake. The control box also applies the park brake if one of the safety interlocks is activated such as the door opening or the key is turned off.

Parking Brake

Service Brake

  • The vehicles standard brake pedal, master cylinder, and load proportioning valve
  • Operation of the service brake is transparent to the driver

Park and Emergency Brake

  • The vehicle’s original park brake lever, cables and park brake are completely removed
  • Operation of the park brake is controlled by an E-Stop button on the vehicle’s dash. The E-Stop button is simply depressed to apply the park brake. The park brake is released by resetting the E-Stop button.
