Great video, have to replace a caliper on the wife’s car this weekend and bought a vac bleeder but had no idea how to use it. Thanks for the step-by-step!
Or it could be the bleeder threads. But none of that matters because while the vacuum is on, it's impossible for the air to go the other way into the brake lines. The air makes it a bit difficult to judge when the bleeding is done.
I'm 56, been working on cars since I was 17 and this is the 1sr time I have ever seen anyone bleed the brakes in that order. Always thought it was the farthest from the master cylinder(most always passenger rear) then drivers rear, passenger front then driver front.. always learning... Have you done one using the software to activate ABS pump yet, if so do you have it online? Thanks enjoyed the video
Pressure bleeder is faster and better and easy/cheap to make (about $40 or you can buy for around $60). Vacuum on brake line can actually cause new fluid to boil inside the lines due to low pressure inside the line. if you vacuum bleed your brakes after major brake work you should let vehicle sit for a day (lets all the tiny bubbles you unintentionally put in fluid merge together) and then com back and manual bleed the brakes at each wheel. Conversely, if you use pressure bleeder, you push the fluid and whatever air exists in the system out the bleeders one at a time w/o boiling the fluid. It's more than mechanical knowledge, it's physical science.
No Cigar. I observed this after a complete brake system overhaul, new Master cyl, new wheel cyls, new flex lines, new calipers. Used vacuum to pull fluid through the lines. observed tiny bubbles throughout vacuum bleed process at all wheels. Maybe my vacuum chamber pulls higher vacuum than yours, I don't know but had to let it set over night and manual bleed the next day to get good pedal. Vacuum bleed still a good method, just not an end, in and of itself.
Not my first rodeo Barry. Tiny little bubbles like you'd see in carbonated drink, homogeneously throughout the fluid. Most certainly caused by to high of vacuum. Not typical of trapped air in the system you are talking of. Analogous to how divers get the bends or what happens to water in an vacuum, it will boil at room temp if high enough vacuum is pulled on it. Air powered vacuum bleeder will not pull the level of vacuum my vac pump pulls. In this case, that's a good thing. All good Barry.
@@x-man5056 The vacuum is in the container attached to the tool, not in the brake system, the system isn't sealed so there is no vacuum pressure built up in there. Its the equivalent of sucking pop through a straw.
@@ewomer100 The fluid in side the lines is under vacuum or the fluid would not be sucked through the lines. The whole system becomes part of the vacuum chamber. Brake fluid is of a viscosity that it is easy to put more vacuum than can flow through the small brake lines if you can apply enough vacuum. If that wasn't so, you'd suck ALL the fluid through the line in seconds. It all depends on how much vacuum is applied. The vacuum chamber I was using can pull a very large vacuum, it was designed for changing oil on inboard boats where draining oil from the oil pan is next to impossible. Designed to pull motor oil up through the dipstick tube through smaller line inserted down to the bottom of the pan. If I could draw you a picture of a system I could demonstrate the phenomena I'm speaking of easily. That said, I have changed my position vs vacuum bleeders. I bought the one from Harbor Freight and used it. I provides a lower vacuum than the chamber type I was using though maintains a constant vacuum. In fact I really like it, it's the easiest way to bleed brakes I've ever used. As long as I have compressed air, it is the only way I'll ever do it from now on. So you win anyway. Peace. ;-)
@@x-man5056 If there was vacuum in the lines the fluid wouldn't go anywhere because the vacuum would be pulling the fluid and air up into the lines, the vacuum is in the tool only, which sucks the fluid through the lines. If using this method and there is vacuum in the lines, there is a clog/kink somewhere and that part of the line/part needs to be replaced.
Love the video but I think I still like the pressure bleed method better. It's cleaner... I'm about to do a Ford Focus 2007 with the Motive method... So far I have replaced struts, springs, rotors, drums and brake linings. Throwing dot 4 ATE and see what happens... If you are interested in the result reply... Still on the project is oil and tranny fluid with Amsoil... Great work guys!

Thanks for the step-by-step!
You know what? I think Im going to go change my brake fluid...Great vid. Thanks!
Great video, best one i have viewed
Very informative video. This guy is knowledgeable and professional!
Great, descriptive video.. and excellent hat!
The connection to the bleeder valve is leaking in air thats why so many bubbles going into the tank.

great video man! you are a good mechanic!
Nice vid. Explained clearly and good filming. Thanks!
Thanks for the demo. Cheers, Peter
Well done. Thanks for the tutorial.
Excellent demo

What is the name of the tool you screwed on the brake fluid bottle???

Appreciate the video and explanations! How often do you recommend that brake fluid be flushed?
He said most manufacturers suggest flushing every 2 years, so I would say go with that.
What if the clutch shares the same tank/container? Do you go ahead with the same procedure?
Same procedure, except with the clutch involved you should also bleed the clutch. So 5 bleed screws, instead of 4. ;-)
Cheers

Thanks Curiosity!! keep up the good work yourself....
