Where to put the break fluid?

This is usually located under the hood on the driver's side of the car, toward the back of the engine compartment. Imagine where your brake pedal would end up if it went all the way through to the engine. The brake master cylinder is a small (about 6-by-2 inches), rectangular piece of metal with a plastic reservoir and a rubber cap on top, and small metal tubes leading from it.

The rectangle reservoir on the top of the master cylinder is where you fill. just take the top cap of the reservoir.

Please rate and god bless:)
