Kobelts 5027-A air applied caliper disc brake is built primarily of bronze and stainless steel. It is using a double diaphram design for accurate control. Also is it providing a solid, long-lasting braking solution for even the harshest environments. This brake is well suited for service braking applications on winches, pleasure craft and other light duty applications.

The 5027-A air brake comes in several different mounting configurations, matched well to Kobelt’s 2″ (51 mm) x 4″ (102 mm) ventilated discs. With a minimum of  28″ (711 mm) diameter and a maximum disc diameter of 75″ (1.905 mm).

All Kobelt brakes feature a shoe design. These allow the brake pads to be easily and quickly changed while leaving the caliper in place.

All Kobelt caliper brakes can be fitted with either air applied, hydraulic applied, spring applied with air released or spring applied with hydraulic released actuators depending on the required service.


The foundation plate to support the brake caliper must be designed to withstand the maximum braking forces generated by the brake caliper. It must also be flat to ISO tolerance grade IT8 and square to the brake disc. A brake pedestal must be designed to allow the mounting bolts to be inserted from underneath. The rotating element should have bearings sufficient to carry the weight of the disc. It also resist the additional stress when the disc brake is applied. The spigot that centers the brake disc must not be designed in such a way that it impedes the thermal expansion of the disc.
Any guarding around the brakes must provide enough room to allow full extension of the brake
actuators plus full pad wear adjustment.

The piping to the brakes must be adequately sized to ensure rapid response times in all weather conditions. The piping must be selected to safely withstand the pressures required to operate the brakes.

For all Kobelt brakes are repair kits available.
