When the bleed screw is loosened, antifreeze is added to the engine’s cooling system and the increase in fluid pressure displaces air through the opened bleed screw. When liquid begins to flow out, all air has been removed from the system and the bleed screw is closed.
Can you bleed brakes without using bleeder screw?
Yes, of course, it is very possible to do this if the bleeder screws of your vehicle are rusty and crusty. You can either use a pressure or gravity bleed method to achieve this. It is a simple process. You can start at the brake that is nearer to the master cylinder.

If what you meant was bleeding the brakes at the calipers to remove air from the system, you should bleed the brakes with the car off.

How much does it cost to tighten a bleeder screw?
One word of warning here – Don’t tighten your bleeder screw with a ratchet. The recommended torque figures for bleeder screws are between 6 lbs-ft to 10 lbs-ft (8 – 13 N-m). You could generate that much torque through a standard 8″ long ratchet if you put two fingers on the handle and gave it a gentle squeeze.
