Brake Beam Guides

Vescolene Ultrared - material of choice for brake beam guides

Problems with metal brake beam guides

Excessive wear occurs between the brake beam and the guide causing the brake shoe to be applied unevenly to the wheel. Both the guide and the brake shoe wear unevenly leading to their premature replacement.

The benefits of Vescolene brake beam guides

  • increased life of brake shoe, guide and beam
  • uneven wear on brake beam guide and brake shoe eliminated
  • brake beam runs true with the correct angle of operation between the brake shoe and wheel maintained
  • optimum braking efficiency
  • smoother brake beam release eliminates brake shoe drag on wheel
  • maintenance and operational cost savings on brake shoes, wheel and track
