GMC Sierra/Chevy Silverado Hydro Boost Upgrade & Replacement 2001-2010 Duramax

This video will show you how to upgrade the hrydro boost on the 2001-2010 Chevy Silverado and GMC Sierra's 2500 Durham to the 2011 LML Duramax hydro boost. The original hydro boost that came on these model year trucks had weak and squishy brakes. The hydro boost that came on the 2011 model year trucks had upgraded internal parts and is an upgrade that works for the 2001-2010 year trucks. This is a complete bolt on upgrade and no modification is needed although there has been a few people that needed to ream out the rod hole that connects to the brake pedal. Hydro boost was purchased from BBP Diesel Performance and here is the link bbpdiesel.com/.... The one galloon jug of pristine power steering fluid was purchased from o'reilly auto-parts.

Thank you for your video, really teachable for a home garage mechnic, especially under the dash. The little retainer clip can become a monster to remove. Only by your clear explaination was it a 10 second install.

[@chriscavaliere8752]

Best video I’ve seen on this fix

[@JohnJacob-qc1we]

Great content. Excellent step by step instructions. Worked like a champ. 2006 Silverado. Thank you.

[@christopherwest5840]

That was great filming of the install of the clip for brake switch assembly

[@dittman2564]

Great video, I just finished installing the Duramax 2011+ hydroboost unit into my 2004 GMC Yukon Denal due to a weeping OEM unit. Brakes are definitely a lot better, and they were really good prior to that. I've been driving this vehicle for 7 years. My manual has a much quicker and easier bleeding procedure than what you did. I kind of did it 50/50, your way/manual way. They don't raise it off the wheels, and they start engine right off and let it idle for a bit, then turn steering left/right several times avoiding hitting the stops, (not allowing it to max out left or right), then check fluid, add fluid if necessary, turn steering L/R more etc.

Super video, quality and description in detail. Only concern i have going in is the not coming out of park issue. I'm installing a new GM unit factory, not upgraded, on an 06 Tahoe so hope no drilling out issues as enough to do it once!! Thanks again for taking such time to cover what reading a manual can not.

[@indiothehauler7418]

Best video I seen so far not sure if I can still do it but this video gives me confidence for sure.

[@indiothehauler7418]

It took me 2 days but I did it. lol

[@jjesusrramirez45]

I WILL INSTALL IT ON MY 04 SUSBURBAN NEXT WEEK THANKS FOR ALL THE EXECELLENT INFO👍👍👍👍

[@FreeLifeFilms]

Did it fit?

[@Re-engineer_everything]

I have a 2003 LB7. I had a built reman, built Allison, built transfer case, sportsman CP3, 30%, 116k, CCLB. I just had a pin hole in the high pressure power steering line develop a pin hole. The power steering pump is now toast. Changing out those high pressure lines if you haven’t yet.

[@glenndavidson692]

I want to thank you this is the best video I have seen on changing out the brake booster out of all the videos. I have a 2004 GMC 2500 H D manufactured early 04. The fuel system parts for 2003. So I'm wondering so you need to drill out the hole on the break booster hole? My question to you is that while I'm there I'm going to replace the master cylinder the truck has $200,000 mi on it. So I'm thinking put the brake booster on first then the master cylinder and then bleed out the are in the master cylinder first then bleed out the booster? Thank you so much for your video. 2011 brake booster.

[@brandoncoston7489]

Little tip for that pesky brake pedal clip, you’ll have it off in 2 seconds like this. Roll it sideways, and stick a 90° pick in the front and lift up the little tab that curls under and then slide it up with your finger, comes off super easy like that 👍

[@ccohen8]

How about getting it back on

[@kseries20-24only]

Great video, and thanks for taking the time to cover the clip on the brake pedal, plus the difference if you go with the 2011 booster!

[@vandersnickmcduffle7333]

I want to do this but I have to lose weight first. I almost died changing my steering shaft and bearing while trying to get up under the dash! 🤣🤣

[@BLUECOLLARGARAGE]

😂😂😂 yeah it’s a tight fit plus it tweaks your back.

[@turbocoupe27]

It's worth it to just pull the driver's seat out to do that job.

[@thesetruths1404]

Hey I have a 2005 Yukon SLT 5.3L automatic with 218,000 miles. All stock equipped. Doesn't make any noise of any kind, that's abnormal. Well kept and daily driver. I drove it out on the highway for 300 miles and when I exited Interstate it was in manual steering mode...stiff to turn like it had no pump at all. And the brakes were not boosted either. It's not the belt or fluids of steering or brakes...all good. No leaks. No codes. No smells. No noises of pump failure. It only does it at low rpms when coming to stop, under 700 rpm. It works fine when above that. And the brakes are unboosted when it does it also, but work. This is the pump I assume? Remove and replace eh? Suggestions of what pump brands you had success with? I'm eyeballing the O'Reily $72 special. Thanks!

[@LyonhartZ2]

INsane Video. Best on KZbin. Thanks for your help man

[@jdscada]

Very Thorough video, Thank You

[@jstraw11]

5/5 great job on the video many thanks!

[@fernandocastorena6381]

Clean shots thanks 🙏

[@bobbymcgee9477]

I’m workin on a 05 that’s got a new pump new hydro booster and brake master and it’s got a normal feel to the pedal but way too much travel and it has 0 powersteering

[@jjesusrramirez45]

good job BLUE COLLAR GARAGE 🙌🙌

[@vermhot]

Will this work also with the 6.0 gas motor ?? New to this and looking for options to make break’s better, thanks

[@lukelowry]

Having my 2012 3500 Hydro Boost replaced next week. How long should this take a shop mechanic to finish? Just trying to budget. Good video, tjhank you

[@BLUECOLLARGARAGE]

Should only take a couple hours.

[@mattmeissner5998]

Great video. I have a 04 LLY & wondering if that hydro boost u upgraded is comparable with a 04 LLY

[@brianhopkins6657]

Great video and well explained.

[@georgecastillo6548]

Nice good job thank you.!

[@AVMAR]

After all is done and bled I noticed a small hissing sound by the pedal when you press the brakes is that normal?

[@mike4796]

Great work with added tips and insight!

[@danieljones8587]

Thanks for the very through vid on how to change out the hydro-boost. I will be subscribing to your channel. I like the way you always have a shop towel in your hand. 👍

[@adrianv2817]

My hydro boost is bad and I went to check my power steering pump to see what color my fluid was and it was milky and delaminated with rust but this truck has been sitting for about a year so would I just need to change the pump and the hydro boost or would I need new hoses and what not hopefully you see this and give me some advice on what needs to be done it’s a 03 3500

[@showalterlifts2020]

Hoses are pretty cheap so it’d be more beneficial to change it all at once

[@andrewdonnelly180]

Anyone know if I could use the 2011 part on a 1500 series truck?

[@sled7782]

Why was the hydroboost replaced

[@rafaelmunoz1633]

So what was the size of the O-ring inside the kit ? If you don’t mind me asking thanks

[@dougsmith747]

Thanks for sharing! 😎👍

[@pdab4372]

Great video!

[@lowlifewill8895]

I wonder if there’s a seal in between the master cylinder and the hydro booster just because I recently replaced mines and still leaks underneath it through the fender well not a lot but you’ll see drips coming out

[@killbengaming8975]

I'm wondering the same thing. Didn't see a seal when removing old one but the remanufactured one calls for one but didn't come with the purchase. This video does not mention the master cylinder flange seal.

[@jesusmayoral2861]

Do you suppose to bleed the hydraulic boost after is installed?

[@tonyostoja8100]

I installed this in my 2005 Sierra 3500 duramax model. Install was straight forward. after the install was completed I discovered by transmission lockout would not release and I had no brake lights. I installed a new stop light switch and the transmission lockout functioned correctly but still no brake lights. Fuses are fine and brake lights work if I jumped the brake light terminals on the connector. Any suggestion on a fix?

[@Kinards_Kustoms]

I believe that is the reason for drilling the hole out slightly, it being the remedy for said problem.

[@zenonmondragon560]

Muy buen trabajo exelente video gracias por tu gran ayuda

[@josephscisson5253]

How can you tell if the master cylinder has to be replaced too or is that strictly with the brakes?

[@JV-bs5bl]

Can this unit be fitted on a 2006 Tahoe 5.3L gas? Also will the brake master cylinder bolt on directly to the new unit?

[@TheRoyJames]

Did you ever find an answer? I'm having trouble finding info. My gut says yes but I'm not sure.

[@Moco925]

Hey have you had any issues with it? I had the same re manufactured it had the pushrod installed already but the instructions still said to use the old one. Was just wondering if it still worked fine

[@BLUECOLLARGARAGE]

Although this is not my truck I still keep in contact with the owner and he has had no issues at all with it.

[@joshuagavin2934]

It says that because their is ones that do not come with shaft

[@someguy1016]

Question: Has anyone put this on a 2006 GMC Yukon XL 2500 6.0 gas. looks like a direct fit. ALSO: anyone know the viton O Ring size?

[@CSWmanofsteel]

I have a 2002 3500 silverado dually 4x4 crew cab with a 6.6 duramax, will this work with my truck?

[@BLUECOLLARGARAGE]

Yes should be the same as long as you have the hydro boost system.

[@CSWmanofsteel]

@@BLUECOLLARGARAGE what’s the advantages of switching to a 2011?

[@jjesusrramirez45]

DID YOU HAVE THE MOTORS RUNNIG AS YOU WAS DRAINING THE FLUID? THANKS

[@BLUECOLLARGARAGE]

No it wasn’t running.

[@noelhernandezphotosimagenc4462]

nice

[@rauljuarez35]

Do you know if it will fit 5.3 or 8.1?
