ProTec Extra Duty 23,000-LB axle rated rigid-molded material is a rugged, dense, heavy duty premium block. TFX23 offers the ideal friction performance with excellent lining and drum wear rates across all operating temperature ranges. ProTec’s unique blend of insulating fibers, bonding resins and advanced graphites transfer heat away from the lining/ drum interface, thus extending wear life while minimizing brake fade and noise. TFX23 delivers cost savings expected by today’s demanding fleet customers.

Recommended applications include tri-axle dump truck, tandem axle refuse, cement mixers, logging, mining, and other cycle-duty heavy haulers.

Compares with Marathon FLOE/HS and Abex 685. All linings are produced in ISO-9001, V2008 quality control standards.
