Mechanical Retention Displaces Adhesive Bonding Across New Platforms
Hooked, barbed and interlocking plate surfaces are replacing pure adhesive bonding on new brake platforms, and copper-free friction chemistry is the reason. The replacement formulations behave differently at the bonding interface, and adhesive that performed for decades began producing delamination claims under hard thermal cycling. A mechanically retained plate holds friction material through shear forces that defeat any adhesive bond, and it removes an entire warranty failure mode from the system. Retention plates cost roughly 2.4 times a flat stamped equivalent, and original equipment engineers increasingly accept that on liability grounds alone.
