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

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

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.

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.

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

Best video I’ve seen on this fix

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.

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

Clean shots thanks 🙏

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

Very Thorough video, Thank You

5/5 great job on the video many thanks!

Great video and well explained.

INsane Video. Best on RU-vid. Thanks for your help man

Thanks for sharing! 😎👍

Great video!

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!

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. 👍

Nice good job thank you.!

Great work with added tips and insight!

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

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! 🤣🤣

good job BLUE COLLAR GARAGE 🙌🙌

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

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

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!

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

nice

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

Do you know if it will fit 5.3 or 8.1?

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 👍

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

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?

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.

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

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

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

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

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

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?

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

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

Muy buen trabajo exelente video gracias por tu gran ayuda

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?

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

I 2006 gmc 3590 sierra. Purchased 2011 hydrobooster installed without issues. Upon install truck will not come out of park. Replacement stop/brake switch and still can't get out of park. If you push on switch with screw driver will shift out of park. What are my options? Troubleshooting? Rumor has it I need to drill out.
