Which of the following is a consequence of wet brakes?

Wet brakes can become weak due to the presence of water, which reduces the friction needed for effective braking. When brakes become wet, the moisture can interfere with the brake lining material and diminish its ability to grip the brake drum or rotor effectively. This reduced friction results in a longer stopping distance and can even lead to brake failure if the moisture accumulates significantly.

The other choices highlight incorrect assumptions about wet brakes. For instance, improved brake performance is not a characteristic of wet brakes; rather, they worsen performance. Additionally, wet brakes do not work consistently because their efficacy is compromised when moisture is present. Lastly, the idea that brakes will get hotter and stronger is also misleading, as moisture generally results in less effective braking rather than an enhancement in brake power.
