Abstract: The present invention provides industrial spring applied caliper braking systems which include a friction disc, a spring applied thruster and a caliper base comprising a friction facing. The caliper base is selectively activated by the spring applied thruster to apply said friction facing to the friction disc, and deactivated upon the application of a minimum pressure to release said friction facing from said friction disc. The braking system further includes a roller guide assembly including a roller guide arm, a high temperature roller wheel disposed on a distal end portion of the roller guide arm. The caliper base and roller guide assembly are mounted to a floating bracket assembly for allowing the caliper base and the roller guide assembly to slide orthogonally to a center line of the friction disc in response to at least thermal expansion driven axial float of said friction disc.
