The clear container with the black and yellow cap at the top-left of the photograph is your brake fluid reservoir.

To pass an MOT your battery must be properly secured. If the strap is supposed to be securing it, it will fail. If there's something else securing it (e.g. A clamp at the bottom) then it won't fail for an insecure battery.

Windshield washer fluid.

If you have passed your test then you should know what the brake and clutch fluid reservoir is as you should be checking it weekly.

As said if the battery is not secured by a clamp at the bottom it will fail for being insecure.

Brake Fluid reservoir. Read your handbook!

  • Will water flood the inside of a car? Say that you drop an empty car into a deep pool of water (deeper than the height of the car), will the inside of the car flood? I know it is a stupid question, but I sort of want to know the answer to that question. I have seen land rovers ford some rivers and they seem fine even when the water was up to the vehicle's hood.

  • How to figure out if an engine can fit inside a car? How can i tell which engines fit in which cars.

For example i could build up a 90's camaro then brop it in an older car, example-69 mustang
