It is well-known that automobile transport as well as industry are the main sources of air pollution. In addition to exhaust gases, the flow of traffic releases a cloud of dust, consisting of over 60% of micro- and ultramicroscopic particles with radius of 10.0–0.25 µm, which are formed due to wheel abrasion (caused by the road grip of a tyre) and the use of the brake blocks (in braking).
The products formed in the process of wearing of the wheel brake pads are also the sources of the mass of fine dispersed particles over an urban highway.
The authors analyse and evaluate ecological characteristics of drum and disk wheel brakes of vehicles.
