KUNZ UTT - Universal Torque Tool for Brakes

Key Tasks

  • Precise, CMM-compliant torquing of aircraft brake fasteners
  • Electronic torque and angle control for repeatable, documented results
  • Enables single-operator torquing of aircraft brakes – reduces personnel requirements
  • Compatible with KUNZ BBS and all major aircraft brake systems via dedicated torque adapters

Overview

The KUNZ UTT Universal Torque Tool for Brakes is a specialised electronic torquing solution designed for the precise assembly and disassembly of aircraft brake systems. It ensures accurate tightening of all critical fasteners in strict accordance with the aircraft manufacturer's CMM, contributing to safe and reliable brake performance.

With electronic torque and angle control, digital readout and full data logging, the UTT for Brakes delivers consistent, repeatable and fully documented results on every cycle. Its ergonomic design makes it possible for a single operator to apply the high torque forces required for brake assembly without physical strain, reducing fatigue and the risk of errors.

The UTT for Brakes is fully compatible with the KUNZ BBS Brake Build-Up Stand and supports all major aircraft brake systems via a range of dedicated torque adapters.

Main Benefits

  • Electronic torque and angle control – precise, repeatable and CMM-compliant results every time
  • Full data logging for complete process traceability and documentation
  • Enables single-operator brake torquing – reduces personnel costs
  • Ergonomic design eliminates operator fatigue during high-torque applications
  • Compatible with KUNZ BBS and third-party brake assembly stands
  • Supports all major aircraft brake systems via dedicated torque adapters
  • Reduces maintenance errors and improves compliance with CMM requirements

Precision Torquing for Aircraft Brake Systems

The KUNZ UTT for Brakes is a state-of-the-art tool for accurate and reliable torque application on aircraft brake assemblies. Every fastener is tightened to the exact specification required by the CMM, enhancing both safety and performance.

The built-in software guides the operator step by step through the correct torque sequence, preventing errors and ensuring full traceability. Work orders can be retrieved via barcode scanner or RFID card, and all torque data integrates with the KUNZ Wheel & Brake Shop Software for seamless end-to-end documentation.

The Perfect Match: KUNZ UTT for Brakes + KUNZ BBS

For maximum efficiency and precision, the KUNZ UTT for Brakes performs best when used in combination with the KUNZ BBS Brake Build-Up Stand. Together, they provide a complete, integrated brake assembly and disassembly workstation – ensuring accurate torque application, reduced maintenance time and enhanced overall safety.

This pairing allows a single technician to achieve consistent, reliable results across multiple brake types, simply by swapping the appropriate torque adapter on the BBS base plate.

KUNZ Wheel & Brake Shop Software Integration:

All torque data recorded by the KUNZ UTT for Brakes can be exported to and managed within the KUNZ Wheel & Brake Shop Software, providing a complete and auditable documentation trail for every brake assembly operation.

Remote Maintenance Support:

KUNZ offers remote maintenance support for fast technical assistance and software updates, minimising system downtime.
