I have spent hours on you tube researching how to bleed a new vw master cylinder that is already installed in the car. For me, this guy nails it which saves me the hassle of removing the cylinder, bleeding it on a bench, and the reinstalling it. The camera work is clear and precise. Thank you!
Thank you you are the first person to actually complete the whole bleeding process from beginning to end... I've watched all the videos and nobody ever completed where they completely bled and hooked it up to the brake lines..
I got a master cylinder bleed kit with plastic hoses and ends for $12. For a single use, that's a lot less than the cost of those flaring and cutting tools used in this video.
If both fittings are the same, there is an even easier way to do this. Stores carry straight, steel lines with fittings for both ends. Just get one about 1.5 ft long with the right fitting size, cut it in half, screw in the fittings and curve the line. No need to mess around with flaring ends and you'll save a little money not buying a whole roll of steel line..
I agree, unless you’re already replacing the front lines it’s not worth it. Personally I’m probably replacing all of the front lines including master so it would realistically be economical to use a reel since it would be extra, assuming I use about 20 feet or less.
I see a lot of other videos using what looks like about $5 worth of plastic hose and fittings to do the same thing. Plus with clear lines, you can actually see the air bubbles moving through.
Lenn,thanks for making a master cylinder bleed much easier than I could of imagined. Your videos are always very informative and easy to understand, thanks again Lester from Canada
Bench bleeding on the car defeats the purpose of bench bleeding, though. For example, on a Jeep XJ, the MC is way tilted back and you end up with a big air bubble at the very front of the MC that you CANNOT remove by bleeding in the vehicle. You need to be able to bleed repeatedly while the MC is gently tilted forward and backward separately. Hence, bench bleeding.
Definitely helped me while working on my 68 C10! I order most of the stuff from Amazon and was able to get it done inside my small little garage lol. Thanks!
Great job Len! *What is a Vericle? An axis or hinge; a turning point. *What is a vehicle? A thing used for transporting people or goods, especially on land, such as a car, truck, or cart. "the vehicle was sent skidding across the road”
New bottle of brake fluid and a thick rubber hose with an OD less than the ID of the original flare fitting for the brake line. Push the hose onto the nipple of the master cylinder port and put the other end into the bottl of brake fluid. It would suck the fluid up the hose and into the master cylinder. Would be cheaper and easier than the method described in this video. Just make sure you only do one fitting at a time, make sure the other fitting has the car's brake hose attached. Rinse and repeat for the other port. This assumes the master cylinder is in the car and the brake lines are attached initially.
A1 Auto, in fact l didn't discover you guys early but is not too late, this bench bleed brake system it''s fantastic l really love it, more videos more education, thanks brothers
thanks 👍 i have a old 69 F250 and i dranied all the fluid from the master cyl and blew air in it to clearout any dirt only i didnt realize i pumped it up with air had a hard time getting fuid to come out of the bleeders going to bench bleed it first now....
Ok so after you bleed the master cylinder do you crack open the bleeding screw for all 4 wheels if everything is new and then press the brakes to bleed? Or do you crack the bleeding screw 1 wheel at a time?
You still gotta buy a flare kit. Whats the point? If you can bleed it on the bench then you can bleed it in the vehicle. Same exact way with the cheap kit. Amazon sells a couple kits for about $10. I used to just hook it up, pour fluid in and bleed at each wheel. I've done it my way since 1965.
The reason you bleed it on the bench is because you need to push that piston all the way to the bottom. If you do it in the car the linkage might not let you push it to the stop.
You technically could get hard lines of junkyard vehicle same make and model. Just cut and clear tubing with tape. Or heat metal lines into shape you need.
i have a 2013 ford edge, the reservoir is longer. just wondering if the process is the same? just having longer hoses would work as long as they reach the fluid at the bottom?
When I removes the bleeder hoses from the master cylinder all the fluid came out before I got to screw in the brake lines into the master cylinder. Is this an issue? or do I have to bleed the master cylinder again?
So ? Forgive my stupidity but if you bleed the calipers well Wont any air in the ststem come out. I just did it and plan on doing it again soon just to make sure !! Please respond
@@1AAuto Hello my car is 1993 Ford Taurus V6 3L and my master cylinder (bendix 12377) have 4 ports (4 brake lines) do I do the same things you did with to bleed master cylinder ,,but in my case i need to put 4 hoses intate of 2 like you show ? thank you
Could you just use a hose, submerged in fluid like in a bottle with some brake fluid, attached to the bleeder on the brake caliper, then start pumping?
It's not recommended from what I've been told. Check around at your local auto parts stores; many will do a basic diagnostic scan on your vehicle for free, but some may have more advanced scanners that will bleed the ABS module for you, or they may loan you the tool. Remember to bleed the overall system after the ABS bleed as well.
Nice, but where can we buy that tool you used to make the stuff, or maybe you can lend me that. I bet that tool is more expensive than taking my car to the shop.
+Jian guo liu We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I'm really surprised at some of the stuff you show here. You show a regular open end wrench to open and close the brake line fittings instead of a line wrench, and you didn't even bother to whip off the booster? It's filthy. Why install a brand new part and leave all the corrosive mess behind? Some of your other videos are really good, this one fails to mention that lots of cars and trucks have MC's that are at an angle when installed, you have to bench bleed the MC level, and at a forward and back angle to bleed all the trapped bubbles out. I have done this many times on the bench and you'll get bubbles out. And showing the flaring of the tubing is great, but you fail to mention that the little plastic kits with hose works exactly the same, and most MC's come with the little plastic screw in fittings to bench bleed. All this could easily have been shown in the same, or less time. I like your videos, it's just that you are showing a method that only works in some cars, and using a line wrench is a really important tool for you to show the public, and inform them why you don't want to round off the fittings on lines. And, using an impact to tighten the nuts that hold the MC to the booster? That's just asking for trouble. All folks have to do is watch a few other videos on this same subject, and they will see with their eyes exactly what I'm saying is correct. I did not put a thumbs down on this video. I simply wanted to make a few points for the folks who really want the best procedure, Thank you.
I appreciate your attention to detail but some one like me whose tired of buying specialty tools just find out I can do it with the regular tools I own is alot nicer than running out a spending money on tools that make the job slightly easier or more professional so I can pretend like I know what I'm doing... I'm all for backyard fixes because tool money can be an issue sometimes and if I'm in the middle of a job and I look something up and they're like you need this and it just be a preference thing is annoying and causes panic.... it just boils down to being careful
I found out the hard way that line wrenches are necessary, apparently even more so with harder metals and flares that are anything less than perfect, so I agree with OP.

This is what I did but with the dormans universal kit since I don’t have a bench with a vice so thank you
When I bought a master cylinder probably remanufactured for my 78 Monte Carlo it actually come with a bleeder kit. It was plastic but it was free.
Why the dis likes??? (Trolls) This is a well informed made video. It's better than the rubber hose kits they sell.

"the vehicle was sent skidding across the road”
Are brake line fittings universal for the most part of would you have to get a bunch of different fittings for different vehicles?
Excellent video very well explained thank you

Rinse and repeat for the other port. This assumes the master cylinder is in the car and the brake lines are attached initially.
When you disconnect the bleed fittings, doesn't that just reintroduce air into the master cylinder again??
This is the way i was taught, over 40 years ago...haveing these metal lines, and the flare tool, is considered a tool to keep in the tool box...

That's very informative and easy-to-use love it, thanks
YOu might think about cleaning the lines that went back into the MC!! The rust and moisture can get into the line.
love the lesson brother
When breeding the cylinder n pushing down on peddle do we disconnect the vacuum hoses or disconnect themm
Super nice and smooth video and great acting skills too 👍
Have not made tubing before except on exhaust . Get pass that I am home free . Good video thanks
When bleeding the rest of the system what do you mean. Bleed each wheel
Yes
That was awesome to watch you guys did a great job. Thank you

The reason you bleed it on the bench is because you need to push that piston all the way to the bottom. If you do it in the car the linkage might not let you push it to the stop.
Great vid! Is there a reason why you didn’t bleed at the lines to the master after bench bleeding?
Thanks. Info helped me greatly.
Very understandable thanks.
that is pretty cool thanks for the tip

Nice Clear presentation, I think I can do this!
Are you bleeding until you dont see anymore bubbles? Or just 3-4 times? Thanks 🙏
Boss i have something to ask ,what is the problem of the brake cylinder,if you use the brake the fluid goes on ther engine
Brake fluid is corrosive and will eat away at paint, chrome and some metals.
You do have great videos. Thanks
Thanks A-1 y'al the best 👌
