    [VIDEO] How to Properly Size and Select a Caliper Disc Brake

    Posted by Troy Branham on Mar 7 ,2018

    Looking for a caliper disc brake for your braking application? There are also a number of cost-effective and efficient brake and disc combinations that should be considered. From active pneumatic and active hydraulic to lever mechanical actuated and spring applied brakes, you can customize your application with the perfect product.

    Each application type requires a different type of caliper disc brakes and features, so we’ll help you narrow down what product you’ll need based on the application you’re using it for.

    Dynamic Stopping

    In order to calculate the amount of torque required for a dynamic stopping application, first you’ll have to collect the following application variables: weight of rotation mass, radius gyration dependent on the shape of the mass, RPM, and stopping time. By combining these variables, you’ll be able to compute the torque that your application is going to need.

    Next, examine the available brake models and the resulting tangential force they provide. Multiply the tangential force with the braking radius for desired disc diameter, and that will tell you if the brake and disc combination has the required torque for your application.

    Frequent Stopping

    Because of the more consistent wear and tear of regular stopping, you should examine the energy generation and heat dissipation to make sure that the brake disc combination can adequately dissipate the heat. Also, look into the friction pad wear life and make sure that the friction material lining and the service life is adequate for your application.

    Static Holding

    Comparatively, these applications are easy, because we just need to know the amount of torque to be held. From there, you simply select a brake and disc combination that matches that amount.


    The purpose of the brakes in these applications is to provide a constant torque to rotating mass to apply tension in material on that roll. Similar to a frequent stopping application, since they are continuous duty, we want to make sure that we calculate the energy generation and the heat dissipation.

    There is a lot to consider, depending on the application that you’ll need a caliper brake for. To view more details, please download the caliper disc brake quick sizing guide, or contact us for assistance.
