25. Si los frenos se mojan...a) Se estropean y hay que cambiar las pastillas.b) El vehículo frena a menor distancia.c) Pueden perder temporalmente la eficacia.

Analyzing the Options

1. Option a: Se estropean y hay que cambiar las pastillas.

   • This option suggests that wet brakes will inevitably get damaged and require replacement. However, wet conditions do not necessarily lead to immediate or permanent damage to brake pads.

2. Option b: El vehículo frena a menor distancia.

   • This option implies that when brakes are wet, the vehicle will stop in a shorter distance. This is generally incorrect, as wet brakes actually reduce braking efficiency due to a decrease in friction.

3. Option c: Pueden perder temporalmente la eficacia.

   • This option correctly states that wet brakes can lose their effectiveness temporarily. When brake components are wet, they may not grip as effectively, leading to longer stopping distances until the brakes dry out or regain proper function.

Conclusion

The most accurate answer is c) Pueden perder temporalmente la eficacia. When brakes are wet, it is common for them to become less effective, which can affect the vehicle's ability to stop safely until they dry or the conditions improve. It’s essential for drivers to be aware of this change in brake performance when driving in wet conditions.
