    [VIDEO] Brake Pads and the Coefficient of Friction

    Posted by Troy Branham on Jul 7 ,2016

    What are the options available to you with friction materials when selecting your caliper disc brake? The main three attributes to consider when selecting that material are the material's wear rate, the coefficient of friction, and its energy capacity.

    W.C. Branham VP of Engineering and General Manager Chad Randleman explains the coefficient of friction in this edition of Solutions in Motion.

    The coefficient of friction is offered in a wide range from .21 up to .55.  

    With .21, on the low end, being suitable for tensioning and constant drag applications, where a low tangential force is required.  High coefficient materials are often suitable for static holding applications where you want to maximize the braking force.

    The different materials available range from organic, to semi-metallic, to sintered metal. all having different energy capacity limits: organic being the lowest, semi-metallic in the middle, and sintered metal in the highest range — so you always want to consider the energy dissipation required for your application.
