Our caliper brakes are made entirely of die cast silicone bronze with stainless steel hardware. The standard lining supplied is asbestos-free with a coefficient of friction between 0.45 and 0.55. All caliper brakes are available with shims between the shoe and the bearing to adapt to thinner discs. Most of our actuators are of the low-pressure type. The maximum pressure for fluid applied calipers (air or hydraulic) is 100 psi/0.7 MPa.
