When braking capability is compromised, the first step is to try to restore brake pressure by pumping the brakes. This action helps build hydraulic pressure in the brake lines again and can bring the pedal back up if it’s soft or fading, allowing you to regain some braking control quickly. Downshifting to a lower gear can contribute to slowing you down through engine braking, but doing this immediately, especially in a vehicle with automatic transmission or at higher speeds, can be unstable or fail to stop you promptly. Steering toward the curb to stop is dangerous and should only be considered if you have no other option and cannot slow safely. Using hazard lights and calling for help is important for warning others and getting assistance, but it does not restore braking; it’s a support step, not the immediate action to regain control of the vehicle.
