What are some symptoms of brake failure?

Symptoms of brake failure include a spongy brake pedal, longer stopping distances, and unusual noises. A spongy brake pedal indicates that there may be air in the brake lines, a fluid leak, or worn-out brake components, all of which can lead to ineffective braking. Longer stopping distances can result from failing brakes, as the vehicle will struggle to reduce its speed adequately. Unusual noises, such as grinding or squealing when applying the brakes, can suggest that brake pads are worn out or that there are issues with other brake components that need immediate attention.

The other options describe issues unrelated to brake failure. For instance, skidding and loss of power relate more to traction or engine performance problems rather than specifically to brake functionality. Steering wheel vibration can indicate alignment issues or tire problems, while airbag deployment is related to crash safety systems rather than braking. Excessive fuel consumption, battery issues, and throttle failure are indicative of engine or electrical problems and do not correlate with symptoms arising from brake issues. Understanding the specific symptoms related to braking systems is crucial for safe vehicle operation and effective maintenance.
