Thanks for having the patience and time making this video. This is an A+ video, and thanks for you help.😊
Wow. Now comments like this, makes me want to make more content. Thank you!
Sincerely appreciate the detail included and the pace that you used to create this incredibly helpful video. I have the same problem that you were yukon has in my 05 denali.
Sir, thank God for your video!!! I've been leaking PS fluid for months and have tried finding the leak, even used UV dye to no avail!! But my leak is exactly where yours was. Also, love your pointer stick!!! Again, thanks!
Thank you very much, this made it all worth while shooting video for this repair. Good luck. Let us know how you did
I just picked up a 2005 Yukon, had the same leak. Your video was beyond helpful, very clear and informative. Awesome work, thank you.
Awesome!! I love hearing you guys getting your gmc fixed..
I did mine in the truck, two things that help.Getting the pins to fit in good.I used a broom handle and pushed slowly on the brake keep it pushed down.This pushed those two pins forward.Simple to just drop into place.Second person on the brake pedal best way.Oh release the brake slowly so you can make sure the pins and that grove they sit in stay in place.Second thing is getting the spring and gasket all put back together.That star at the end ,that your spring rod goes through.That is easy to remove,be careful just pry it out of it's grove.Do it from the back after you have separated the piston and spring.Dont try and take it before separating unit.Put the unit back together with out the spring or star.Makes putting it together much easier.Once everything back together slide the spring in from the back.Line the spring rod up and push on the star.I use a socket on a extension.Push on the star until it sits in it's retaining grove.Doesnt take much effort to push it in.
thanks for your input
Very nice video old man! Love that you actually cut out pieces from paper to demonstrate how it works 😄. Im gonna have to do this job on my Tahoe cause that gasket is leaking a little.
It's for the spacially impaired.. good luck.. thanks for stopping by youngster.
Again, 2022, I own a 2004 Suburban 1500 LT 4WD, thank you for a awesome step by step tutorial to DIY! I’m definitely that guy, and will be messaging you regards another issue I’m having regards starting!
Your welcome
Thank you soooo much for taking the time to put together a great instructional video. I'm about to go rebuild mine now but wanted to let you know how much I appreciate you sharing your time with us.
Thank you!! Let's me know how it went. Good luck.
I like the cut-out arrow vs the jazz hands in most videos
Thanks for the cooler/hose box idea! I feel a bit stupid i had not thought of that maybe 20-30 years ago!!
yea till me about it. it saved my back, i wish i would have thought about this sooner myself.
Thank you sir, excellent video, everything very well explained, loved your white arrow at the beginning
thank you very much!
Thank you so much for the video U saved me greatly literally 30 minutes prior to watching your video I went to O'Reilly's and bought power steering pressure lines and hoses preparing to do a task non necessary thanks again keep up the good mechanical work
Your very welcome!!
Great video with the visual aids. Very helpful. Thank you.
you're welcome
At the end you say, congratulations gentlemen. Well include the Ladies too because I followed along with your video and was successful. I have also done my knock sensors myself as well. Thanks you are a great teacher
Wow. the world is now a better place now. you don't know how much this makes me feel, this is why I do these videos! trust me, it's a great feeling to see people saving tons of money. I'm going to mention your name on my next GMC video. Thanks, again Karine !
I will be sure to check it out. I think my starter is trying to go out too. Do ya have a video on that? Thanks again!
Don't have one yet, but its coming soon.
Thanks for the video. This was a big savings and when you said by the small electric component I'll thank you later you meant it . Glad I brought a new one, the old one fell apart when I took it out.
Oh the brake switch. yeah there made of plastic and become brittle. Glad you saved some big money!
Those arrows you use are great!
Thank you!
Intense yoga training! Love it!
LoL! Thank you!
What a perfect upload as I just started having this exact problem on my 2006 Yukon Denali XL. Thanks so much. I'll post again with any helpful comments once I get some time to do the replacement on mine.
Man you're the truth! You need to do videos on how to use your interior controls from lights to tailgate switches, I see no videos of this!
how to use them or how to replace them?
@@notsofast2325 how to use them, a1auto got the good videos on replacements, but don't let me shoot your dreams down,lol do everything, maybe you can do commentary on their videos or do your own, you earned a subscriber in me!
@@notsofast2325 look around the web ,blogs even here on RUclips, there's no one dedicated person or place that specializes and specifies in the 2000-2006 model yukon, especially the specific trim of the denali! Remember the Suburban, Tahoe, Escalade & Denali all are built on the same platform too, so that's more views for you, its all about specifics these days, lol
Trust me I know, I have one coming out tomorrow, next will be replacing my fender, then a rocker panel, then how to repair the DVD player, placing the center console cup holder area, brakes, wiper motor, door lock repair, map lights, glove box lights,grill replace, headlight replace, fog replace, side mirror replacement. Bumper replacement, licence plate bulbs, where's my cigarette lighter fuse, etc..
@@notsofast2325 look up after market dvd players with tv on eBay, sum nice upgrades out there!
Nice job on this video,I've done the seal kits 3 times.I finally bought a new unit,your video will still come in handy.
yeah someone told me there are good O-rings and bad ones.. mine is still working.
Yesterday me and my dad changed the gaskets in there and at first there was no more leak I was so happy then we drove to O'Reilly 4 min away and back and when I was parking and got out the truck I saw a huge puddle or powersteering oil like hugeeeeee puddle and me and my dad wjere so confused because we did everything so carefully and correct then we noticed a huge string of power steering fluid coming out between from the break booster and the hydroboost we literaly worked for 5 hours on that for us to fail this showed us that it's better for replace the whole part instead of trying to fix it because we just wasted alot of time and energy it literaly ruined my week no I have no truck until I raise the money to buy the part and find a good mechanic that can come and not charge me an arm an leg for that job
You should install it yourself and save on labor.
One of the best instructional video's I have every seen! Thank you!
Wow! thank you very much!
Best video for the hydro booster i have found. Great job.
well thanks you c\ever much !
Thank you for a no BS how to. Was very helpful and saved me some money. Again thank you.
Some money? Dud I saved you some serious cash. your welcome.
Thanks for the video. I have this problem with my 03 Denali. I am gonna buy a new hydrobooster though.
There not cheap. Good luck.
@@notsofast2325 $185 but, worth it.
This video was absolutely outstanding. Changed mine today, thanks!!
Awesome, and thanks for your input!
Sr...this is the best video I found about this....thank you stay safe
thank you , it took a lot of work to video this project. i have seen some of the other youtube video and saw the things they left out. so i tried to fill the gaps. I hope you get to see my other DIY videos.
great video thanks, the demonstrations was a great touch to show how things go back together, sometimes thats not obvious! got me through my booster replacement!!!
Awesome!! Bet you saved a lot of $$$. Thanks for letting us know how you did.
My 98 Chevy one ton hydro boost is leaking so this video will help me a lot when it comes time to deal with it. Thanks! Nice editing too.
Awesome, this is the reason I made the video, Your welcome .Check out my other diy gmc videos
Oh yea. It's on my 2004 chevy Tahoe
Excellent video. The mock ups really helped. Thank you.
Your welcome! Thanks for stopping by.
i love how people block their license plate on vids....but drive around the country with it showing daily lol.
As you know you have to show your license when you drive. But there are a lot more eyes on the internet 24 hrs a day. There's a lot of bad people out there. So you try to minimize the problems as much as you can.
Bravo! Two thumbs up with the tutorial pic layouts and verbal insights.
Good details about the yoke and the slot. Good details about critical direction of the lip seal. I replaced mine and still leaking on the master cylinder side so maybe I had debris in the hole. I plan to reassemble and hope it stops leaking. I thought I had lip seal facing wrong way but I did it right. Here is the kit I got from amazon ZFLXH For Hydroboost Repair Kit Chevy GMC Ford GM Dodge Seal Kit Hydro-Boost Leak 3 Piece
Thanks for your input!
Did you get yours to stop leaking? I did the same thing, and it's still leaking, and the power breaks are not working well now. Did you end up getting a new seal kit and redoing it and fixing it, or did you have to buy a new hydroboost?
Thanks!
Thank you so much for the video!! I jus finished my 2004 Silverado!!
you saved a lot of money didn't you...
very informative and useful. thanks, will redoo my work again...(bought some unoriginal gaskets, not recomended!) on the hydrobooster with this in the background 4 shure
Good luck. And thanks for stopping by.
This video is very easy to follow and thorough. Thank you.
Glad it was helpful!
Best video on this on RUclips
thank you. i just rebuilt mine. and wouldn't you know, Just yesterday seen one at the junk yard for 25.00 bucks. At the time i needed one nobody had one. you look on ebay they want $250 to $450 for one. So that's when i decided to rebuild mine. it takes some time but do able. Check out my give away on my last video, watch the whole video to see the details. thanks again.
Great job on your video. Best one on this repair I have seen.
Thank you !
Great video. 1 suggestion would be to loosen all the bolts while the booster is still in the truck so you done have to struggle breaking them loose on the bench.
If you can get a good grip on the bolts, go for it. Thanks for your input.
Great video thank you, for being so descriptive. I'm not much of a mechanic but I feel i can do it.
Take your time. Lay out everything. If I didn't video this it would have taken me about 30min. Look at the gasket in the cylinder see which way the gasket is sitting. You want to get that right.good luck, let us know how you did.
Wow your in Vagas? I love to play craps..
Thank you sr. 4 the video just replaced mine, thanks to your very well explained video, thumbs up 👍,
Glad it helped
Good job explaining sir

Other than the leaking fluid, was there any other symptoms that there was a problem?
Amazing video! Thank you so much!
Your welcome!
Thank 😊 🙏 I'm trying to do it myself
Take your time. Stay focused. Good luck.
Great video and I like your white arrow
Thank you.
Thank you so much very helpful video..
You very weclome.
My local garage wanted $1,800 to replace the hydro-boost unit.
I know, isn't that crazy?
Thank you gentle. It is a Good job.
thank you !! Thanks for stopping by.
Any chance you would know the size of the O-rings that go on the power steering hoses to the Hydro boost.
Thanks for the marking the video.
sorry i don"t
The trick to putting it together is installing the spring loaded part in the notch first. I also left the back part still connected in the engine bay, just get towels and remember to discharge the pressures first.
thanks for your input.
How do you discharge the pressures?
@@thejuice7924 pump the brakes until it’s tough to push, turn the steering wheel a few times, with the car off.
@@torchwork8651 thanks!
This was the best vid in seem so far... Ill be back out to my truck today... One question... Do I have to add power steering fluid?
to your power steering pump only , yes.
Did you have a whining noise also with this issue? Because I’m having a whining noise like it’s the power steering but I’ve had that checked and flushed and still whining. When I press the brake the whining noise also gets slightly worse.
whining noise like you described is typical of low power steering fluid. In my experience, the noise goes away when you fill the pump.
Yea I know but I’ve done that & no change. But I also have messages that state check brake system and check brake booster so I’m just going to change the hydro booster & master cylinder.
Mine is leaking as well but the problems I’m having is with the stability control the brakes lock up you think that the leaking hydroboost is my problem ?
The power steering pump and brake system is tied together as you may know. As you press on the brake your creating pressure within the unit, if there is lack of pressure because of the leak yes your system will not function properly and your brake system and your stability will try to overcompensate it. I'm not a professional by any mean. But i can tell you this ,if it is leaking dont drive it , especially if your towing something. The fix is a cheap fix. Yes it takes time and yes you'll be on your back . But once your done you save $500 to $950 in repairs, and a sense of satisfaction that you were able to do this. Good Luck
That's help full thank you
Glad it helped
great video I'm glad I found it thank you its one of the best videos out there.
ive bumped into an issue when I put everything back together I start the engine and the brake pedal goes in on its own and makes a grinding noise < do you know why that happens ?
Make sure all your hoses are correctly installed..
@@notsofast2325 yeah thanks! for some reason as soon as I start the engine the brake pedal gets sucked in instantly , I might need to bleed the lines .
Does that if the yoke comes out of slots. That's what mine did found out after pulling it apart again.
Thanks,great explaination. ck
Np
Awesome video, it seems like you actually don’t have to take it off the firewall. Do you think it is possible without doing all the interior duties?
you can do that if you want. But i wanted to completely inspect the unit.
Your awesome thank you!
Well thank you!
thanks
Im glad this video helped you..

I'm having trouble getting enough clearance to get the switch and rod over the brake post
just keep working at it. it will go in.
I did finally get it, I didn't want to break the switch. Funny I got out a pry bar and before I used any force. Big enough gap to get it all together just happened.
Saving this video.
Question, could someone do it without having to go under the dashboard?
there are people that say you can. but remember there is a spring and clips in there and will shoot out. and if you loose them , you cant buy them , you have to buy the whole unit. so i rather work on the bench , So its up to you..
@@notsofast2325 thank you!! I will try this this weekend, which is the correct repair kit?
🧰 🧰🧰🧰🧰
Wow! Thanks. newbie here Learning mechanics. Question why did you take the whole hydro booster off the firewall if all you needed was to change the gaskets. Why not leave the entire hydro booster connected to the firewall and just remove the ebolts and separate the Hydro booster while it’s still connected to the firewall. Isn’t that more efficient on time. Is that possible?
Thank you, So typically what I do is Pull the bad Part get a new one and install it. But when I got to the part store I found out what it cost they're expensive. even on eBay an Amazon they cost a lot. I don't know about you but I love my money. So I asked around if these can be rebuilt no one could tell me if they sold a rebuild kit and no one knew how to rebuild one. further than just outright buying one. so I did some research and found they rebuild kit. then I went on RUclips to see if I can find someone that has rebuilt one before. I did find some but they were poorly done so I decided to make a RUclips video on this subject. if I known what I know now I probably would have attempted 2 remove only the what part like you suggested. But for me it was too late plus I didn't know what it took to rebuild one. You can try and let us know how it turned out. I hope I don't have to do this again it was kind of a pain but doable. I kept my eye on the prize cuz I knew I would be saving big money if I did it myself.
@@notsofast2325 hey man thanks for the response. I value my money too. They are charging me $800. I rather use that money to buy tools and fix it myself. I have basic tools at the moment and rather use that money to upgrade my tools and fix it myself. Thanks for including the tip in the video to turn on the vehicle and turn left and right. That will allow me to know if it’s a gasket issue or hose. Great tip!
@@demodemo9698 No Problem..
I’m curious. Why can’t it remain bolted to the firewall? Then you don’t have to deal with all the other BS. I’m asking because I’m about to try it once I get my new gaskets….
You can if you want to. For me I wanted to inspect the back part of the booster. Plus for me it was easy to pull the back part out. If you watch the video you can see there are springs and the figure 8 gasket, internal parts that have to go in a certain way. If you can do this with it bolted on, more power to you go for it. Good luck. Thank for stopping by.
@@notsofast2325 thank you for the response. I’ll let you know what I decide to do and if it worked or not.
@@johnfinch9407 thank you.
You can ,be super careful taking it apart.There is a small check valve that will shoot out in pieces if any pressure is left in the unit.Getting the inner seal in place with out pinching it going back together can be difficult.First attempt leaked from that seal getting pinched.
I can’t find the gaskets on rockauto. Where did you get the parts?
read comments below.
Where'd you get these gaskets?
Ebay

Great video. Just wanted to put my input in since I have watched several of these videos on the tube.
I notice that everyone breaks the E bolts loose AFTER they Remove the Hydro Boost from the fire wall.
Wouldn't it be easier to crack the 5 E bolts loose B4 you remove it from the fire wall. Just wondering.
Also you mentioned to put lube the figure 8 gasket with brake fluid. I think it needs to be lubed with P. Steering fluid.
Yes your right. P. Steering fluid.Thanks for the input. There was another guy that said the same thing. If you can connect the yoke,. And don't loose the spring and clip, ( because you won't be able to find a replacement ) then go for it. I myself have never took one apart. so i wanted the whole part in front of me, so i can see want i was dealing with.
Where did you get the gaskets? The dealer doesn't offer them
ebay.
Mine is leaking from the two bold ..is it just the o ring that needs replacing
Yes
It is leaking from the inside, so your going to have to rebuild it.
I can't fit under where the brake pedal is to get to the clip?...anyone else with big hands and broad shoulders had any success doing this????????
Ask a Friend with small hands to help.
If I did exactly what you did, I won’t have to bleed the brake lines?
The brake lines do not connect to the hydro booster.
