BEST ways to bleed brakes (one person VS. two person method)

Getting the air out of the brake lines is important but you also want to make sure that you get the old fluid out of the lines at the same time. I use the one person brake bleeding method to get the old fluid out, but in order to ensure you get all the air out, you need to use the two person method. There have been times where the bleeder screw itself introduces air into the system. This is frustrating, and this is why I use both methods to get the job done. Hope you enjoy the video.

When flushing you can have the hose below the bleeding valve, but when removing the air, the hose should be *above* the bleeding valve, that way the fluid can flow back into the brake caliper by gravity instead of being pulled away from the caliper.

[JeffTheHokie]

I once had a bleeder that looked like an IV bag with a magnet. Stick it to the fender above the bleed screw. Air rises and fluid sinks. It did a perfect job.

Also:
Start with wheel furthest from abs - generally this is rear passenger side.
Can use 3/16 or 5mm tube.
Add mini cable tie at each end of tube.
Put catchment bottle above not below nipple height - air rises in tube.
If ask for dot 3, then dot 4 or dot 5.1 ok but NOT dot 5
Put cap on bottle to stop water not air getting in.
Check fill level of master cylinder once done - usually don't fill to top once completed - fill to mark on cylinder.

Thanks mate, this is the most complete tutorial on YT, a brilliant, precise, and clear explanation, on how to bleed brakes... Good day to you sir, and greetings from England

Hey folks at 4 minutes he’s referring to dot 5 brake fluid. You DO NOT want to mix this if your system is for DOT3. However it is ok for you to put DOT 3, 4, or 5.1 in a DOT 3 system. DOT 5 is a silicone based system while all others are glycol based.

Byfar the Best explanation on bleeding your brakes I have seen. Thank you

[michaelmclernon]

By far the best video I have seen on the subject.I too, like to finish off the job using the two man approach. One thing I think could have been emphasized a little more with the two person part is the importance of holding the pedal in the down position until the bleeder valve is closed.I have been using this method forever, and always had good results, it is quite easy to get into the sequence if you use the same person to push the pedal every time. (My Wife)!Kudos on A GREAT carefully explained, and well done Video.

One can do the "2 person" method by having a means to hold down the pump. Some use a stick or some such between the seat and brake. I use a heavy tool box. Anything to jam against the pedal that will hold it down solidly will work.

[zlatkozivkovic]

Yes, this is a very good tutorial. Done it quite few times and never had air in the brakes issue. It may be simpler to do it by using the vacuum pump but when i was learning how to do it, that was not available ...so i used my mom to pump the brakes...lol...and she did it without complaining.

[andrewwilson]

I have been using my vacuum fluid extractor to bleed brakes with great success. The strong vacuum and lots of it really pulls the fluid through with enough flow to pull any air out with it. Testing on a brake tester after this process has proved the brakes to be exactly the same as new which is not surprising as this is how they are done on the production line.

In the 2 man operation never pump the brake Paddle to fast you could airate the brake fluid

[djslow]

Put grease around the bleeder screw and it wont suck in air during your 1 man operation. Never had a problem in 30 years

Mate different brake fluids DOT3/4 have different boiling points that's something you should know, nothing about damaging something. For breaks with drums you'll use DOT for discs you'll use DOT4. If combination of both DOT3. Always refer to manufacturers advice.

It doesn't matter if the collection bottle for the old brake fluid is above or below the drain plug valve with the 1 or 2 man system.
What's important is that the clear drain hose is long enough to have the hose above the drain plug before it turns downward. Any air you are expelling will rise in the drain bottle so you will only get brake fluid returning up the hose when you let allow the peddle to return up again.
I put a strong magnet on the bottom of the Energy Juice bottle with a tight hole in the caps top for the hose. Then I place the bottle on a flat piece of metal to prevent tip overs.
I follow up with a second flush doing a reverse flush pushing up any possible air in the lines and allowing them to escape through the Master Cylinder.
And you don't have to keep adding any more brake fluid.

It's amazing all the misinformation presented on the internet and even from the one man brake bleed kit manufacturer. I'm glad I watched your video although I already finished my brake bleed. After reading and viewing all this misinformation, I reflected on all the years I bled brakes using two man and the failed one man products and methods marketed by manufacturers. I found the two man method and master cylinder pressure method would be best. Many people don't take into account the many ways to introduce air into the system.

[IsshmanGarcia]

FYI= that one man bleed system has a one way check valve that allows you to pump the brake pedal and let it go( it stops air from getting into the system when you let off the pedal) and repeat. Its NOT just a tube at the bottom of bottle.

[erickrodriguez]

The two person method way is the exact same way we bleed aircraft brakes, the only difference is that we have loud as hydraulic pumps running and radios to communicate

[jaredbradley]

The one person bottle method. Hose needs to be higher then bleeder screw. Air rises...

[kevina]

Put the bottle higher then the bleed screw... the bubbles will stay higher and not float back to the top aka back to the bleed screw.... I use this same method except I use a Gatorade bottle made in the same fashion as the small one...

[BaeLasso]

You need to put the bottle higher than the brake caliper so that the air could "float up"
