After more than a century of pursuing traditional practices largely dictated by the dominance of internal combustion engines, the automotive industry finds itself in a period of unprecedented transformation. This shift is largely driven by the widespread adoption of electric vehicles (EVs), which have prompted innovations across every automotive sector. Notably, advancements in vehicle braking systems are at the forefront of this evolution, as the pursuit of enhanced performance and safety meets the imperative of minimising environmental impact.
Regenerative and friction braking in EVs
Electric vehicles use regenerative braking alongside conventional friction (hydraulic) braking mechanisms. Regenerative braking, made possible by the advent of vehicle electrification, harnesses the electric motor to recuperate a significant portion of the kinetic energy dissipated during braking – a substantial leap forward in terms of sustainability. Through regenerative deceleration, electric vehicles effectively convert the electric motor into a generator during braking manoeuvres. While the potential for energy recuperation in EVs is subject to certain limitations, regenerative braking plays a pivotal role in deceleration, reducing reliance on traditional friction brakes. However, the integration of regenerative braking presents accompanying challenges. While advantageous, regenerative braking alone is insufficient to halt a vehicle and prevent collisions, underlining the continued necessity of conventional friction braking systems. Consequently, vehicles equipped with regenerative braking systems are also equipped with friction brakes for scenarios where the former may be insufficient or inactive.
Brembo’s EV-focused aftermarket solutions
The prevalence of regenerative braking systems in EVs has led to a shift in how braking is actioned, with a significant proportion now executed by the electric motor itself. Consequently, hydraulic braking systems are implemented less often. While this reduction minimises wear on the hydraulic brake components, it also makes them susceptible to corrosive deterioration, posing risks to both the durability and efficacy of the braking system. In response to these challenges, Brembo, a leading Italian brake manufacturer, has introduced the Brembo Beyond product line – a comprehensive range of aftermarket solutions designed to enhance the driving dynamics of the growing electric mobility segment, while prioritising sustainability.
Comprising specially coated discs and innovative brake pads tailored for popular electric car models, the Brembo Beyond EV Kit epitomises the company’s dedication to harnessing cutting-edge materials and technologies to deliver both superior performance and longevity. Notably, the incorporation of a special, copper-free friction material with a galvanised backing plate reduces both dust and noise during braking – contributing to an extended lifespan and enhanced sustainability. In addition, a special surface treatment on the disc prevents oxidation problems up to 60,000 miles and beyond.
In the workshop
As the automotive landscape undergoes a paradigm shift, workshops are already anticipating and adapting to the unique challenges posed by electric vehicles. With distinct design and maintenance requirements, electric vehicle braking systems require particular, specialised knowledge and expertise.
Key considerations for technicians
Pad and disc replacements: Due to the regenerative braking system, the intervals between pad and disc replacements in EVs are typically extended. However, technicians should remain vigilant for signs of oxidation, particularly in vehicles operating in harsh weather conditions where brakes are used less frequently.
Brake fluid replacement: While traditional replacement intervals are generally recommended for EVs, low viscosity fluids are preferred to ensure optimal performance, especially in vehicles equipped with advanced braking and traction control systems.
EV brake pads: Given the reduced ambient noise of electric vehicles, minimising any brake noise, vibration, and harshness (NVH) is paramount. Special attention should be paid to brake pads and discs to prevent excessive corrosion. This will ensure consistent, reliable braking performance even after prolonged periods of inactivity.
Despite the challenges posed by the transition to electrification, the automotive industry stands to reap substantial benefits in terms of performance and sustainability. Brembo's unwavering commitment to innovation and the environment underlines its pivotal role in driving this transformation forward, as exemplified by the Brembo Beyond product line and its contribution to a greener, more efficient future.
