Should i use anti seize on bleeder screws?Asked by: Lisandro Orn

Actually, since the only reason to recommend against using anti-seize on the threads of this tiny part is because of the risk of getting the torque wrong, overdoing it and stripping the threads, and because this torque is so very small to start with, the risk of applying too much is made greater by the use of a ...View full answer
Likewise, people ask, What type of tool should be used for the bleeder screw?
The Brake Bleeder Wrench has a standard size of 5/16 in. x 3/8 in. This wrench is used for bleeding air from brake cylinders with bleeder screws.
Correspondingly, How tight should bleeder screws be?. Just tighten it by hand. It doesn't need to be super tight - just wrist tight is fine. Just turn it until it stops and apply a *little* bit of force to snug it down with a combo wrench. If you really need the torque wrench because your wrist feeling doesn't work... a small inch-lbs wrench is all you need.
Also asked, Can a bleeder screw go bad?
I guess it's possible that in the chroming process they got enough chrome in the hole that the bleeder can't seat properly, but bleeders usually don't go bad unless they get plugged up.
What does a bleeder screw do?
A bleed screw is a device used to create a temporary opening in an otherwise closed hydraulic system, which facilitates the removal of air or another substance from the system by way of pressure and density differences.
The most common cause of spongy brakes after bleeding, is contaminated brake fluid. Usual contaminates include air or moisture in the system. Most common causes, include: Brake bleeding technique.
Re: Brake bleeder screw size??
IIRC, the bleeder screws are 8mm/5/16". The screws holding the rear wheel cylinders (if drums) on may be a 10mm hex head.
A brake bleeder screw is as it sounds — a screw that enables bleeding. Its threads are tapered to fit snugly into the caliper, preventing fluid from bypassing it to get to the outside.

Q: Can you bleed brakes without using a bleeder screw? ... You can start at the brake that is nearer to the master cylinder. Ensure the master cylinder is at the maximum gauge. If you want to change the old fluid, remove the whole fluid from the master cylinder, and replace it with new fluid.
If the brake pedal height is normal, and does not get harder when you pump it a few times, then there is probably no air in the hydraulic system. If that is the case, driving it with a broken off bleeder that is not leaking fluid is not a safety issue.

3/16-inches by 5/16-inches is typically the perfect size. Once you start bleeding the brakes, the tubing will feed the fluid and trapped air bubbles into the jar for easy cleanup.
To do the job, you need either a brake bleeder wrench or a combination wrench that fits the bleeder nozzle on your vehicle, a can of the proper brake fluid, a clean glass jar, and a friend.
If you are trying to bleed the air out of your brake system, the answer is a resounding no. By simply allowing the brake fluid to move from a firewall mounted master cylinder reservoir to the brake calipers (or wheel cylinders) using gravity, the fluid is moving too slowly.
The master- cylinder cap should be removed during brake bleeding. The correct sequence of bleeds must be followed. Some cars require a different order than others, so you bleed the brake furthest away from the master cylinder.
Should the car be on when bleeding brakes? If you want to force the brake fluid out using the car's brake pedal, the car needs to be on with the engine running. Otherwise, you can do it without having to start the engine.
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. While 'pump' was the wrong word to use, the brake booster runs off the engine vacuum (it's a large diaphragm that multiplies brake force), and this should not be active.
The bleeding process basically involves applying brake pressure, slightly loosening the screw - about 1/4 of a turn - to raise the end of the screw and allow air and fluid to flow into the hole at the bottom, through the screw and out the hole at the top.
Bring the coolant level to the "Cold" mark. Replace the radiator cap. Locate the bleed screw and place a pan on the floor to catch the coolant that will come out through the screw. Turn the bleed screw 2 turns counterclockwise and attach the end of a 4 feet, clear hose to the bleed screw.
