SIBS Polymer Brakes

What are SIBS® Polymer brakes?

Branded under the name ‘Terra Dura’, the new SIBS® Polymer brake represents a substantial step forward in sealed braking technology. While still delivering our trademark quality and durability, the Terra Dura brake’s features and more attractive price point broadens the range of vehicles and conditions for which they are suited.

Key components include:

  • Revolutionary light weight casings made of glass reinforced polymer, making them 40% lighter than SIBS®4 brakes
  • High performance monobloc radial mount callipers
  • Completely enclosed, dry disc brakes that can withstand heavy duty braking temperatures
  • Simplified design has reduced prices, making them affordable to both industrial and retail markets
  • Compact design allowing the brakes to fit inside standard wheel rims
