Brakes should be tested as you set off.
The brakes should not feel spongy or slack also the car should not pull to one side.
(remember they do wear out )
Any problems have the system checked.
Modern cars are fitted with a diagonally split dual circuit braking system. If one of the brake circuits fails, the other remains operative.
If a brake circuit fails, you will at first experience a softer feel to the brake pedal. You will then need to exert a greater force on the brake pedal and make allowance for increased stopping distances.
Have the braking system checked by an expert before continuing your journey (Call the AA).
Disc brakes
wet brake discs result in reduced braking efficiency.
after going through deep water try your brakes to remove any water.
Brake fluid.
