Wear and noise problems in rail systems. Especially in urban inner rails systems are disturbing the environment. In
rail systems, many materials are used as brake material. Composite braking materials have been developed to eliminate these
adverse effects. In this study, the adhesive wear characteristics of the composite brake material used for braking of railway
vehicle tools at different loads were investigated. The tests was carried out on two different braking loads, 15N and 30N, with
composite sabo section as abrasive material and as abrasive surface with 220 mesh roughness. The total duration of each test is
15 seconds and the track taken is 10m. The counter-friction material has been renewed for every application. The amount of
water added in the aqueous media tests is fixed at 200 ml. At the end of the test, mass losses in aqueous and dry media were
investigated. In the conclusion is the following; Mass loss is less in aqueous media. However, similar studies have shown that
the productive frictional force decreases, especially at high speeds. Although not very effective in sudden braking, the inefficiency of mass loss caused by friction can be reduced by using the appropriate continuous braking during cruising.
