HOW EURO 7 EMISSION STANDARDS AREAFFECTING BRAKE PADS FOR PASSENGERCARS, VANS, TRUCKS AND BUSES

Urban air pollution is caused not only by exhaust emissions but also by non-exhaust emissions (NEE). It is now acknowledged that a percentage of urban air pollution is attributed to NEE. Brake wear is one of the sources of NEE. When brakes are applied, the friction between the AUTOMOTIVE BRAKE PADS and disc generates tiny particles that are released into the atmosphere. Manufacturers may need to innovate in brake technology due to the impact of Euro 7 standards on NEE. These standards are likely to prompt further investigation and potential regulations.

Passenger cars and vans are increasingly using electric and hybrid technologies, which reduce brake wear. Regenerative braking systems use the vehicle's electric motor to slow it down, reducing the reliance on traditional friction brakes. Euro 7 emphasizes lower emissions, which will likely accelerate this shift. As a result, brake wear will decrease, leading to reduced NEE from these vehicles.

Trucks and buses pose a greater challenge due to their size and weight. They require robust braking systems that generate a larger amount of brake wear particles compared to passenger cars. Ferodo is exploring advanced materials for AUTO BRAKE PADS and discs that produce fewer emissions when worn down.

Electric trucks and buses are not as developed as passenger EVs. However, their growth will bring regenerative braking to larger vehicles. This would extend brake life and reduce NEE. Euro 7 could speed up the transition to electric commercial vehicles, indirectly benefiting the environment by reducing brake wear.

As the industry progresses with these innovations, Ferodo is monitoring brake wear emissions closely. Real-world, on top of laboratory and dynamometer testing, is providing accurate data on the effectiveness of new brake technologies in reducing NEE. This could result in further revisions to regulations, guiding in producing the most environmentally friendly brake systems.

The EU's commitment to reducing vehicular pollution is evident in the introduction of the Euro 7 emission standards. While exhaust emissions have been a focus for some time, non-exhaust emissions, even from brake wear, are now receiving attention. The automotive industry is poised for another significant transformation, with innovations in brake materials and wider adoption of regenerative braking systems. This will contribute to a cleaner and sustainable future for urban mobility.
