Determination of the shear strength of brake linings

Universal testing machine inspekt table 250 kN

Testing system

The inspekt table 250 kN tensile testing machine can be used to test the shear strength of brake linings. A special version of the testing machine was developed for this testing task and its equipment can be individually adapted to customer requirements:

  • Safety door for safe testing
  • Specialized shearing device
  • Hydraulic unit
  • Testing tools for precise adaptation to the carrier plate & friction lining

Test procedure

  • The brake lining is clamped in a special holder for testing shear forces
  • The adhesive connection between the backing plate and friction lining is subjected to a defined shear force (test force from the side and from above).
  • The measurement is carried out until the adhesive joint fails.

Relevance of the test

The demands placed on brake pads are constantly increasing - higher vehicle masses and more powerful engines require improved braking performance. The quality of the adhesive bond between the brake pad and backing plate is crucial for safety, performance and comfort. The knowledge gained in the shear test can be used in research and development as well as for quality control.
