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.
