Bonding types

The friction material is generally glued onto the backing plate. In order to maximise the shear strength we use a variety of different bonding types, dependent on the weight and/or performance of the vehicle.

Spigot holes:


This is one the simplest bonding types. Following attachment to the backing plate, the friction material projects into the spigot hole, helping to increase the shear strength.

Crimping:


In this method small hooked spikes are machined onto the backing plate, in order to improve the attachment to the friction material and increase the shear strength.

Bolt version:


This process is patented by TMD. The backing plate is fitted with spun-welded brass bolts, specially designed to increase the shear strength.
