- I made a big mistake when rebuilding this Hydroboost unit. Perhaps I can keep you from making the same error.

Very valuable info here and what a great guy. Well spoken, no uh's, clear, intelligent, honest and humble. Thanks for the lesson Jesse. Also no stupid annoying music.
At 10:39 he says umm. 😁
your the only one that talks about dump valve and the different check valve is spot on
I hate it when you remove the last bolt and springs and gears and check valves go everywhere.Thanks for this upload!
Thanks Jesse: Any of us who has worked on equipment has destroyed something somewhere along the line. Certainly I have.
I just want to say that i too made the mistake however didnt have the same damage as you did. i lost the ball and the plastic piece on top of my computer . because i left my hydro boost on the firewall. and just split it to take it apart. pedal slammed to floor just like yours when i turned the engine on. thankfully i came across your video and found the plastic piece but the ball was lost. so i ran to a u pull it junk yard and snagged one out of a unit. saved my ass thank you so much.
Jesse sorry about your fail with the check ball! Wish I could say I've never screwed up, but I can't! I appreciate you doing this video for the heads up! I got a 1996 2500 burb that has the hydro boost and that damn thing has leaked ever since I bought it. It's finally time to fix it. I went through 3 quarts of power steering fluid this last summer pulling my camper and boat. Now it's winter and the fluid just pores out of it. I was very happy to hear you say you ordered your seal kit from PirateJack! That's where I got mine and your right they didn't charge shipping. Anyhow great video very informative! Thanks again for making it.
R Moss good luck on your rebuild! cheers!
My brakes slammed onto the floor really hard too. Stay tuned to hear what Im about to discover...great vid. Thanks
I am getting ready to rebuild mine. I am pretty sure you just saved me the saved me from having the same problem. Thanks for sharing .
Thank so much for posting your mistake! I had that same piece fall out an I had no idea where it can from and the directions ARE NOT CLEAR enough! Your humility in posting your mistake saved me a lot of headache and money. I'm absolutely grateful! Thanks Jeese
Derrick, I am so glad I could save you from this nightmare. feedback like this is the encouragement I need to keep making videos. I hope you will be stopping in no time. let me know how your installation goes.
Thanks for sharing brotha. I can tell youre a really good person. Stay strong and keep helping people. Knowledge is power. I love classic cars, just learning what i can every chance i get.
Thanks for letting us learn from your mistake I'm rebuilding mines now and will be on the look out for this
Great video. And your close up shots did the job perfectly. I'm going to be rebuilding mine soon and I will NOT forget to double check the ball. Thank you.
Did your have the ball in there? I am pretty sure mine did not, but am afraid to put it back together in case I lost it.
I just took mine apart, and sure enough that valve fall under the truck. I had too watch you video 4 times to make sure everything is going back correct. Found the little pin but no little ball. Are you sure there is one in the little yellow plastic valve? I am putting in together tomorrow.
This was a great video. Watching you and your buddy mysterious Mr. "Dark Jacket" get that thing apart. Wrenching at it's best.. Thanks for sharing. I'm gonna get one of those impact drivers.
james f thanks for the encouragement. mysterious dark jacket guy is my dear old dad.
Great Video! Love that we're your #1 source for the kit! Let us know if you need anything. Happy to help in any way!
Thanks for the video and the info. I was doing some research before rebuilding mine on my 01 ram 3500. Definitely helpful. Thanks for sharing your fail. I also got my kit at Pirate Jacks, before I saw this video. Anyway, thanks again!!
I think the instructions showing a check ball are an older or different model.the instructions from pirate jack show a completely different check valve assembly,maybe an old style.i think the little rod with the ball on the end takes the place of the seperate ball. word of warning, i bought a cheep rebuild kit ,i had to push the little rod into the valve with a pair of pliers,this caused the rod to not move freeley back and forth. now when i turn the steering wheel my brakes apply themselves. i've ordered a better kit
I was wondering the same thing. I’m working on a 2006 duramax and don’t see a check ball that’s separate
Very helpful, thanks for sharing your learning process ( not a mistake) that's what UA-cam is all about. Guys like you helping others
Glad it was helpful!
Good to know from your experience i just did my booster fixed last week and bought the Kit from amazon similar kit for 45$ i only used the piston seal and it did the work stopped the leak.
Great video! Thanks for sharing that "lil" mishap. VERY Helpful!!
Thanks, I think I threw away my check ball when I threw out my towel I had my hydrobooster on. If I don’t find it I’m gonna be the new owner of a new hydrobooster, thanks for the info.
very helpful, very informative. thx for sharing
Albert, this unit came out of a 1984 one ton. it should be the same as your 1985. I hope you have smooth sailing on your projecy!
Nice video. I'm glad Pirate Jack has worked out for some folks, but for my 1986 GMC C6000, it was a failure. I had ordered their "fits all" package. When I finally got it, I opened the shipping package. I looked through the plastic bag at the seals, excited about getting my truck running again. I put the my old seals next to the bag and and discovered, nothing matched. Totally useless. I thought about returning it until I read about a 20% restocking fee for free shipping orders. Ehh, not worth the time, trouble or expense for a few bucks. It's now my new paper weight. So don't be so sure Pirate Jack has your cure all. Hey! I'll sell you my unopened package for a couple of bucks less than I bought it for. At least it won't go to waste.
Wish u still had it !! Lol
I probably do have it somewhere. @@danielmarkle8823
Just FYI, the accumulator is charged when the PS pump is running (engine running) and is meant to give some brake assist in the event that the engine dies and you're still rolling. The accumulator gives 2 or 3 semi-power assisted stops, but is not used during normal braking operation.
On some models, the accumulator is charged with nitrogen gas, how is “the accumulator charged when the PS pump is running” ?
As soon as my other parts come back from the powdercoating shop, I'll be putting everything back together an I'll let u know how things work out.
thanks brother very good info
what year is your truck, mine is a 1985 dually and i do not want to make the same mistake. tks
Good day;
My neighbor has a 2000 chevy 2500 diesel 4wd and brake pedal went to floor.
IT has the hydraulic Fluid booster .
I tinker and want to try save him a buck.
No complaint of steering issue.
I felt underside at Master & booster union and feel minimal fluid. No puddle or honest trace of a external leak.
I let truck sit for while, hit brake pedal- to floor.
I let truck run a bit then shut off - pedal to floor.
I held foot on pedal and started - no build up.
If I take foot off- pedal will return out.
I have not worked on a hydr, just the old canister suction type.
Have you come across an internal?
On another vid it was concluded a ABS pump was the prob on a like issue.
I think the pedal/ start stop engine pre tests lead me to the booster.
Greatly appreciate your thoughts if I have misunderstood sequence of diagnosing.
Best; Tom

Thank you!!!
i had to use a pipe wrench and a 3 ft pipe to get that damn nut off...i didn't trust using heat since i was gonna reuse the HB
Too late. I replaced mine without taking the whole unit out of the truck and taking the unit apart on my bench. Instead I split it in half in the engine bay and guess what fell out without me knowing it, that valve and the ball leaving only the plastic piece in there. After it not working after re-installing the hydroboost I found your video and found the metal valve under the truck. Pretty sure all the pressurized nitrogen is gone now and need to go buy a new one :/
Was yours the 2500 HD?
@@TheNomanzero I believe so. I got rid of that truck and bought another GMT400 instead of the GMT800
I have a 1990 GMC Topkick (24 Foot,) that has a very hard pedal, and no brakes. The pump, booster, and master cylinder have been replaced before I got the truck. Trying to find someone that has some knowledge with these. Any help would be appreciated. The steering works fine, but when you are working the brakes, the pump doesn't even sound like it's working, no whine. The little aux. motor comes on when the engine is off, but again, runs free, and doesn't sound like it pumping against any pressure.
Thanks.
kutzbill did you ever find out what's wrong with your truck? I'm having the same problem with mine.
great video. i made the same mistake and had the same problem
Ive got a stupid question, ive got brake fluid leaking on the bottom of my hydraboost and im wondering if its the actual hydraboost leaking or the master cylinder?
If its brake fluid its the master cylinder
To be absolutely crystal clear, are you saying the part shown and described at around 3:35 is the check valve, and was not installed correctly because it wasn't pushed in all the way?....Or are you saying there is a separate check ball, in addition to this piece, that is not shown because it was missing?
Thanks for your help.
I never saw a check ball in my 98 gmc during disassembly. Didn't actually see it in this video either. Help!
So I had a similar or same issue, when I turn on the truck the pedal goes to the floor. when I turn it off the pedal goes back out. I struggle so much with the brakes. I had no brakes, I had to bleed the system so much but no response. when I took the hydroboost apart I saw that check valve but it never came out.
That check valve stay inside, I even remember pressing that valve and I saw a little bit of fluid out but nothing out of order.
Anyways this could explain why my pedal goes to the floor. I could not figure out what was wrong with the system, I took it to the shop because I run out of ideas, I replace the power steering pump. The shop said it may need a new hydroboost which is very expensive right now but at this point I am letting them replace it which is costing me an arm and a leg but now I am letting them see if they can fix my no brakes issue. when the truck is off, you can feel the brake pedal (very hard) when the truck is on the pedal is suck and goes to the floor.
This is the same issue I had. If the check ball is seated correctly, I am not sure of another component inside the unit that would cause it to fully charge when started.
I have a 95 Chevy g20. I got stuck. Pulled it out. I have no power steering and a hard brake pedal. Could it be the Hydro boost unit?
Sounds like the pump to me
the actual diagram for the ram shows it does not have it let ya know if it works
I have 2 milwaukee cordless impacts. They are somethin else. Dont know what did without em
My accumulator is loose and leaks from there. Can I fix the accumulator part as well???? Or am I dead in the water? 😢99 Chevy Astro
did yours leak after reinstalling the hydrobost? mine did not leak, I simply had no brakes, the pedal would go to the floor every time I start the truck. no brake pedal.
what were the symptoms you had after installing the hydroboost incorrectly?
Mine did not leak. The brake pedal was stuck to the floor, when I rebuilt it incorrectly. It sounds as though your problem could be the same as I had.
@@jessebaremore sadly It was the same problem. My hydroboost did not leak but brakes did not work. I had to get a new hydroboost and the problem was solved.
Moving forward I will just replace.
My pedal is now working with no issues.
@@Keepin-it-wheel101 darn! I went through the same. I feel your pain. Glad you have your brakes back!
Will this cause hard steering?
Lost my ball, where to get one, what size is it
Nice video man I've done that on rebuilding a transmission lost a little ball fortunately caught the mistake before throwing it back on.tried looking for piratejack.com maybe typing it wrong.
I have rebuilt or resealed mine twice. Both times two different kits the last 2 weeks then they leak like crazy
Yes thank you . I did not receive any instructions with my kit…
Hello, what were the symptoms when it failed? Thanks.
good question, i replaced master cyl., bled well, same spongy brakes...abs/hydro-boost??
Jesse, I just took one apart and it does not have the check ball between the plastic cup and the valve. You think some units come without them?
I have the same question I have a 99 cummins and seen a forum set by step with HD pictures take that little peice off and no check valve ball. I'm paranoid if mine did or did not have one when I put it backtogethr
@@robertnalls3428 I'm pretty sure you'll be good. Had a friend take one apart that he had laying around and all it had was the plastic cup and the valve sitting on top with the small (rod) or pin that slides in the tiny hole of the valve. No check ball at all in it.
@@turbot84 thanks for the reply..... And that's how mine was until I saw the dang video lol
@@robertnalls3428 No problem. Had me in a panic to.
@@robertnalls3428 SO did it work? I'm in that position now. No Check ball and I didn't remember having the rod.
so if that is lost any clue as to what the size of the bearing is
If it looks the same as my unit in this video, I would be willing to bet that it has the ball. As far as the dimensions, I am not sure. It would have been good of me to measure. I think you may have some better information and success if you call Pirate Jack. They have been helpful to me in the past.
I hope you get it figured out!
@@jessebaremore Its the mystery ball. No info anywhere at all. Nothing. I'm gonna blow my shit up. It's not in any crappy drawings either.
@@TheNomanzerosoo true man! Here I am Sunday night. Nobody knows, I'm going to chance it and actually let everyone know. Stay tuned folks!
ok so I have a question I am working on a 99 ram 2500 and was super careful taking it out but no ball now I don't want to put it back in without knowing if it's needed or not
😒
as far as I know, most units are the same, however I have not had one apart on a model like yours. I'm not sure I could give you an answer. if you sent a picture of your unit, and the parts in question, I may be able to give you more info. good luck!
+Jesse Baremore it looks just. like yours
From researching, it looks like there are 2 different styles. One has a small spool with an o-ring (has a ball bearing) and another that has a plastic insert that does not have a ball.
+Bill Webster, Thanks for your great comment. I have a 2001 Silverado 2500HD. It has the yellow plastic insert similar to the one shown in this video. I'm not clear on whether there is a check ball missing, or if the part shown around 3:35 in this video, is the check valve. Your comment is that the yellow insert type does not have a separate check ball of it's own? Thank you.
Wish I had seen your video before I took it apart
Love
94 Chevy k3500 here I got real tired of replacing the hydroboost... it seems to start pissed fluid ever year and a half and at almost $300 each I figured there's gotta be a better way... I found a couple videos on here ordered parts and I was super careful to not disturb the check valve. I just replaced the main piston seal and the 2 on the input shaft re assembly and my pedal drops to the floor.... now the unit is back out on the bench and the check valve was still in its place I actually had to wrestle it out of its hole and behind that was just that yellow plastic piece ...nothing inbetween. The kit I ordered has the new valve and yellow piece but no ball...I'm goin to reassemble and hope for the best... if anyone has anything info on this disappearing ball please let me know.
Well I successfully reassembled my hydroboost with just that yellow plastic piece and the check valve....no little ball in between
I just took apart a hydroboost from a 94 Astro Van, also being VERY careful took it apart looking for the check ball (I watched this video ahead of time) and there wasn't a ball, gonna call Pirate Jack on Monday and ask, there kit does not have a ball??
there is no ball guys, it's you tube after all, make final judgement yourself
@@planktonus
Thanks Ivo, I have to agree, I found another diagram showing it to be a dump valve with an o-ring with the plastic piece being a two-function valve and a valve seat ( NO BALL ), not sure why Pirate Jack would have a link to this video, very misleading. Here is a link to the other diagram:
constructionmanuals.tpub.com/14050/css/Hydroboost-Troubleshooting-160.htm
@@planktonus I thought so but when I reassembled and the pedal slammed to the floor I had second thoughts....just tryin to verify... but I wound up buying another reman unit but kept the core so next time... I hope to have something to swap in real fast and rebuild and put on the shelf.... ive become real good and gettin that thing out and back into the truck.
stering box was leking so put new one in now it seams like the presher wont flow. and brakes are stiking
Shalum akhy good video. noticed your Tzittzityot and had to comment.
Wells this just happen to me. I should of found your video before I took it apart.
Of course i see this now after it happened to me.... i cracked the case and the valves fell out. I watched a quick video on how they sit (nothing about the little ball). Throw it all back in and BAM. 250$ down the drain.
Lessons learned. Sigh, I wish I would have done better on mine the first go around!
This other video ua-cam.com/video/1tr3vHl1zhA/v-deo.html showed NO ball bearing in the unit he was rebuilding, but my diagram shows a ball bearing. How sure are you that the missing ball bearing is REALLY the culprit that ruined your hodro-booster, or that it isn't used in some models? Thanks.
Love
