Due to the imperfect design of the brake lever transmission, uneven brake shoe wear occurred, which led to:

• increased rolling resistance and excessive fuel consumption;
• loss of braking efficiency;
• premature replacement of brake shoes (service life was reduced by a factor of 3);
• wheel damage, increased repair costs, and disposal expenses.

An engineering-based modification of the triangle linkage kinematics was implemented, eliminating the harmful torque. The system was enhanced with a guiding mechanism that equalizes the gaps between the brake shoes and the wheels when the brake is released. The solution was tested in a pilot on 10 wagons, confirming its scalability.

• wedge-shaped (klinodual) wear eliminated;
• brake shoe lifespan increased from 70,000 km to 210,000 km;
• reduced repair and replacement costs;
• reduced diesel fuel and electricity consumption;
• improved operational safety.

• ₴727,725 in savings per wagon over the estimated service life (22 years).
• ₴62.7 billion — potential savings for the entire fleet of freight wagons (over 86,000 units).
• ₴4,155 per wagon annually — the effect of reduced harmful emissions and fuel consumption in diesel locomotive traction (environmental efficiency component).
