If your brakes fail while driving, what is the appropriate first step to take?

When brakes fail while driving, the appropriate first step is to shift into a lower gear and use the emergency brake. This response helps to slow down the vehicle effectively. Shifting into a lower gear aids in reducing speed through engine braking, which is a crucial technique in managing a situation where the primary braking system has failed.

Using the emergency brake, often referred to as the parking brake, is also vital as it is designed to apply braking force independent of the standard brake system. Engaging the emergency brake gradually is essential in avoiding skidding or locking up the rear wheels, which can lead to loss of control. This combination of actions can help bring the vehicle to a controlled stop in a safer manner.

In contrast, pulling over immediately might not be the safest choice if you are still moving and require immediate action to reduce your speed. Accelerating to gain speed is dangerous since it would increase momentum, making it harder to stop the vehicle. Sounding the horn to alert other drivers does not address the immediate issue of losing braking capability and would be less effective in preventing an accident compared to the actions of downshifting and using the emergency brake.
