Production battery EVs tout regenerative braking and "one pedal driving" as a prominent feature. Regenerative braking utilizes the vehicle's electric motor to slow the car down. While this is great for energy reuse and saving brake consumables, the factory fill brake fluid is not up to the task of spirited driving. Given the massive amount of friction necessary to slow down the weight of a modern EV, it is easy to overheat the OEM fluid leading to loss of pedal feel or, worse yet, serious brake failure.
