4-Layer Backplate Technology
ProRev pads are engineered from the ground up for commercial vehicle duty cycles — not adapted from passenger car formulas.
The 4-Layer Cast Iron Backplate System
Cast Iron Backplate
Precision-machined cast iron provides dimensional stability under extreme thermal cycling — no warping, no flex.
Adhesive Underlayer
High-temperature bonding compound eliminates mechanical fasteners that can loosen under vibration.
Copper-Free Friction Material
Proprietary CF23 formula delivers consistent friction coefficient across the full operating temperature range.
Chamfer & Slot Pattern
Precision chamfers and slots reduce initial bite harshness, channel heat, and prevent glazing during high-frequency stop cycles.

Engineered for Commercial Duty Cycles
Thermal Stability
Cast iron backplate maintains geometry from −40°F cold starts to 1,200°F sustained braking. No delamination, no hot spots.
Noise & Vibration Control
Precision chamfer geometry and slot patterns reduce brake squeal by up to 40% compared to stamped steel backplate designs.
Extended Service Life
CF23 friction formula is optimized for the stop-and-go duty cycles of transit buses and refuse vehicles — not highway passenger cars.
