A defect in the braking system can interfere with a vehicle's ability to:

Explanation:
Brakes are what let you slow down and come to a stop. If there’s a defect in the braking system, you can’t reliably turn pedal input into the friction needed to reduce wheel speed. That means your ability to slow down or stop is reduced, which shows up as a soft or sinking pedal, longer stopping distances, or the vehicle pulling to one side when you brake. Since the brakes’ sole job is to decelerate and stop the vehicle, a brake defect directly affects slowing or stopping. Steering, accelerating, and shifting gears rely on other systems, so they aren’t the primary issue caused by a brake defect. If you notice brake problems, slow down safely and seek repair promptly.
