The water gets into the brakes and when you stop there is less friction.
Stopping distances increase on wet roads because water reduces the friction between the tires and the road surface. This lowers the vehicle's ability to grip the road, resulting in longer distances needed to come to a complete stop. Additionally, water can cause hydroplaning, where the tires lose contact with the road surface, further impacting braking effectiveness.
Two reasons. The wet road has a lower coefficient of friction that the dry one. It is more slippery. The same goes for the brakes. If they are wet, they will be less effective because of the same reason. A higher amount of friction wastes more energy, in this case momentum, causing a loss of speed. http://en.wikipedia.org/wiki/Friction
Driving on tires with no tread poses significant risks, including reduced traction, increased risk of hydroplaning on wet roads, longer stopping distances, and a higher likelihood of losing control of the vehicle, especially in adverse weather conditions. It is important to regularly check and replace tires to ensure safe driving.
It has long been known that a decrease in tyre tread depth can lead to the deterioration of a tyre's performance during cornering, and straight line braking in the wet. A tyre is unable to deal with the same volume of water on the road at lower tread depths, which means that the tyre is unable to transmit traction and braking forces as effectively. Previous studies had confirmed this relationship, however there was a need for independent testing to quantify the effects on typical cars found on today's roads. In 2003, the British Rubber Manufacturers Association (BRMA) commissioned MIRA to study the effects of tread depth on stopping distances. The study was carried out on MIRA's test track in Nuneaton, and 5 different tread depths were tested - 6.7mm, 4.1mm, 2.6mm, 1.6mm (the legal minimum) and 0.9mm. Vehicles were mounted with equipment to record time, speed, and distance. The tests were carried out on two different surfaces at the testing track, hot rolled asphalt and smooth concrete. In order to ensure the accuracy of the results, the tests were repeated several times. The stopping distance was recorded at each of these tread depths and the points plotted on a graph of stopping distance versus tread depth. A line was drawn through the points to show the trend between stopping distance and tread depth, from which information could be taken.
Speed: As speed increases, braking distance increases because the vehicle has more kinetic energy that needs to be dissipated in order to come to a stop. Traction: Higher traction allows the tires to grip the road better, reducing braking distance. Lower traction conditions, such as wet or icy roads, can increase braking distance due to reduced grip. Gravity: Gravity affects braking distance by influencing the weight and load distribution of the vehicle. Heavier vehicles may have longer braking distances as it takes more force to slow them down compared to lighter vehicles.

Increased stopping distance-danger of hydroplaning
The stopping distance at 25 mph can vary based on factors like road conditions and vehicle type, but a general rule of thumb is that it takes about 59 feet to stop. This includes the reaction distance (approximately 19 feet) and the braking distance (about 40 feet). Always remember that stopping distances can be longer on wet or icy roads.
The normal stopping distance can increase by up to two times when driving in the rain. This is due to reduced traction on wet roads, which can lead to longer stopping distances and increased risk of accidents. It is important to adjust your driving behavior, increase following distance, and slow down in rainy conditions to stay safe on the road.
The highway code typically includes information that is relevant to the majority of driving situations. Stopping distances greater than 70mph are less common and may be considered atypical. Additionally, including stopping distances above 70mph may give the impression that driving at those speeds is safe, which is not necessarily the case. It is always important for drivers to adjust their speed and maintain a safe stopping distance based on the road conditions and their vehicle's capabilities.
Stopping on snow and ice may require up to ten times more distance than normal conditions due to reduced tire traction. It is important to drive cautiously and leave plenty of space between your vehicle and others to allow for increased stopping distances. Using winter tires or chains can also help improve traction on snowy and icy roads.

Engine braking is not recommended in certain situations because it can cause excessive wear and tear on the engine and transmission components. This can lead to increased maintenance costs and potential damage to the vehicle over time. Additionally, using engine braking on slippery or icy roads can cause the wheels to lock up and result in a loss of control.

Breaking on wet roads is more difficult than on dry roads because water reduces the friction between the tires and the road surface. This decrease in friction makes it harder for the tires to grip the road, resulting in longer stopping distances and increased risk of skidding. Additionally, water can mix with oil and other fluids on the road, further reducing traction.
