However in special situations, harsh and aggressive environments, there was a need for more durable and more powerful brakes. The biggest advantage of wet multidisc brakes is that they can be used in big variety of conditions, from extremely cold to the extremely hot, from very clean to very dusty environment and so on. Because of their very responsible part in heavy machinery design, wet multi-disc brakes presents a very attractive and hard task as for mechanical engineer as for researchers all around the world. This paper presents a practical approach to wet multi-disc brake design improvement. Namely, the most of present wet multi-disc brakes uses a radial placed compression springs for brake activation. This solution leads to lots of difficulties during brakes manufacturing and brakes maintenance. At this paper is presented concept of compression springs replacement with belleville springs. Concept is proven by hand and FEM calculations. At the end of the paper conclusion and further research directions are given.
