it is harder because there is less friction with lubrication -which is what water is -and you need friction for the breaks to work
Yes. There is less frictional force between the car tyres and a wet road surface than with a dry road surface.
Stopping distances are increased on wet roads because water reduces the friction between the tires and the road surface, making it harder for the tires to grip and stop the car effectively when the brakes are applied. This reduced grip means it takes longer for the car to come to a complete stop compared to dry road conditions.
it is your tires
yes
When the road is very wet, the tires lose contact with the road..
Less traction on a wet road so the stopping distance increases.
Stopping distance
the belts on your car get wet
A car is harder to steer when it rains as the wet surface effects its traction and maneuvering. The tires also respond differently in wet conditions.

At 20 miles per hour it takes about 60 feet to stop on wet pavement. At sixty miles per hour it takes at least 300 feet to stop.
