German automaker Mercedes Benz is at the forefront of a revolutionary endeavor - reinventing electric vehicle brakes. In the realm of modern cars, disk brakes are commonly used, relying on calipers, brake pads, hydraulic fluid, and pistons to slow down wheels through friction. However, electric vehicles present a unique challenge as they are heavier and have greater torque. This has led to the development of a new type of brake specifically designed for electric cars.

Mercedes-Benz's 'In-Drive Brakes': A Game Changer

The Mercedes-Benz 'in-drive brakes' are currently in the development stage at the R&D department in Sindelfingen, Germany. Unlike conventional disk brakes, this new system resembles modified clutch plates and is integrated into the drivetrain, functioning similar to a transmission brake. It features a circular brake pad directly connected to the electric motor's output shaft and forced against a stationary water-cooled ring. This enclosed system eliminates the need for a traditional caliper with attached control arms and brake pads.Mercedes engineers have been meticulous in their design, devising a hidden compartment to hold brake dust. This not only reduces the need for frequent servicing but also potentially saves EV owners thousands in repairs and replacements. In contrast, regular electric vehicle brakes typically need to be replaced every two to five years, depending on usage, and require more constant maintenance.The new electric vehicle brakes will also play a crucial role in reducing pollution from brake dust. This fine powdery residue can damage wheels and be a significant pollutant in urban areas with heavy stop-and-go traffic. By storing the brake dust in a hidden compartment that doesn't need to be emptied, the risk of brake dust-caused wheel damage is minimized, and brake dust pollution is reduced.While the new EV brake is still in development, its integrated nature holds great promise. It could help customers reduce maintenance and repair costs and carmakers reduce manufacturing costs by minimizing raw material usage. If it reaches production, it could be a game changer for the nascent electric vehicle industry.As these new brakes are commercialized and adopted by startups like NIO Inc. (NYSE: NIO), the electric vehicle landscape is likely to take a new trajectory. This could make electric vehicles more affordable and appealing to buyers, further driving the growth of the electric vehicle market.
