Discover Why Brake Pads and Discs Last Longer in Electric Cars, Understand the Role of Regeneration and How This Technology Reduces Costs and Environmental Impacts.

The arrival of electric cars brought not just cleaner and more efficient engines. The way these vehicles use brake pads and discs has transformed the automotive maintenance experience.

Unlike combustion models, where mechanical friction is responsible for most of the deceleration, electric vehicles rely on energy regeneration. This technology increases range, spares the brake system, and ensures a longer lifespan for the components.

Electric Cars and Cost Savings at the Workshop

One of the major attractions of electric vehicles is the reduction in maintenance costs. The absence of a combustion engine eliminates the need for services such as oil changes, filters, and belts. But the benefit goes beyond that. Brake pads and discs, which traditionally require frequent replacements in conventional vehicles, have significantly greater durability in electric models.

The Secret Lies in Regeneration

The electric motor is not just for moving the car. When the driver decelerates or steps on the brake, the motor acts as a generator, recharging the battery and creating a natural resistance to movement. This process, called regeneration, slows down the vehicle even before engaging the mechanical brake system.

According to Carlos Augusto Roma, technical director of ABVE (Brazilian Electric Vehicle Association), “this process, called regeneration, already strongly decelerates the vehicle, reducing the need to use the mechanical brake system, made up of discs and pads.”

Less Heat, More Durability

The reduced use of the mechanical system decreases heat generation, one of the main factors contributing to wear on discs and pads. This not only prolongs lifespan but also reduces the risk of overheating during successive braking.

Roma compares it with the reality of conventional vehicles: “In a combustion vehicle, almost all deceleration comes from the friction between the pad and disc. This generates heat and wear, requiring replacement on average every 40,000 kilometers depending on use. It is common for EVs to run 80,000, 100,000 or even 150,000 km before the first pad replacement.”

Intelligent Integration Between Mechanical and Regenerative Braking

In many electric cars, the transition between regeneration and hydraulic braking is electronically controlled.

The system applies as much regeneration as possible and only engages the mechanical system when truly necessary. This means that the pads are activated, most of the time, only in emergency situations or during very intense braking.

Environmental Impact and Cost Savings for the Driver

In addition to cost savings, the greater durability of discs and pads brings environmental benefits.

As friction is lower, the emission of fine particles and pollutants released during braking also decreases. In other words, electric cars contribute not only to combating air pollution but also to reducing waste generated by maintenance.

Even with this extra durability, there is one point of attention: the fluid in the hydraulic system. Over time, it absorbs moisture from the air, which can compromise braking efficiency and cause corrosion.

For this reason, manufacturers recommend that the fluid be replaced at regular intervals, according to the vehicle’s manual, even if the pads and discs are in perfect condition.

Environmental Impact and Cost Savings for the Driver

While in Brazil a 10-story building takes 2 years to complete, in China a company stacks pre-fabricated modules and raises the entire building in just 28 hours and 45 minutes.

Egypt wants to draw 10 million cubic meters of water from the Nile per day into the desert, irrigate a new agricultural frontier, and build a city where there is currently only sand.

BRICS is preparing a payment system inspired by the Brazilian PIX that will allow direct transactions between countries using national digital currencies without relying on the dollar or Western banks as intermediaries.

Ethiopia has banned gasoline and diesel cars, placed over a hundred silent electric buses on the streets of Addis Ababa, and now aims for half a million electric vehicles by 2030, all powered by Africa’s largest dam and a courage that few countries have shown.

A view from space, an image made by NASA shows the impressive Richat Structure, a geological formation located in the Sahara Desert, also known as the “Eye of the Sahara.”

Created to cling to ships like a lamprey, the new U.S. underwater drone sleeps on the ocean floor, launches torpedoes, and recharges itself with the current.

Solar-powered ice factory in the Amazon that eliminated a 5-hour trip to Manaus, prevents the loss of up to two-thirds of the fish, and now ensures income for more than 30 riverside families.

NASA identifies rare organic molecules on Mars with Curiosity and reinforces that the planet once had an environment favorable to life

Apes also play make-believe, a study with bonobos points out, and reveals similarities with humans

Cheaper than expected and with a cut of up to 50% in taxes, the Golf GTI may arrive in Brazil at a reduced price after the EU-Mercosur agreement and Volkswagen’s strategy that promises to turn the tide by 2041.

A type of soil that occupies only 3% of the Earth can release more carbon than all the forests on the planet, and scientists warn that the degradation of peatlands can transform this silent reservoir into a global climate bomb.

While you sleep, an artificial intelligence trained with 600,000 hours of sleep can predict 130 diseases — including Parkinson’s and cancer — years before the first symptoms.
