Well done! One of the best step by step videos on this topic. Thank you for posting this. Update: Finished mine today. Went well but finding a 41/64th drill to ream out the push rod to the same diameter as the original one was tough. The 2011 hydro-boost that I installed in my 2006 is a big improvement on braking. But the hole on the push rod is slightly undersized. Hence the 41/64th drill. Once we got that done, it went well. Thanks again!!

Maybe a dumb question, can the rod be taken out and swapped? I haven't done this repair yet and was curious.

How do you know if your hydroboost is no longer working my pedal is soft pads are good pushed the rear pistons in when doing the parking pads wonder ifI need to lead the breaks my service brake system warning message is on as well.

Normal reasons for changing are it is leaking and or steering issues is why I did mine. Couldn't steer while braking.

I just replaced mine and the brake pedal vibrates when I step on it I’m thinking the air got in to the system can you can give me some info?

Has to been the plastic brake switch that goes on the pin for the brake peddle. I had to replace mine, but it was awhile after doing the swap. It kicks the cruise control off as well.

I didn't hear you say why you were changing out the hydro boost or how to diagnose a problem with it. I have an 06 GMC dump truck and am not sure if I need a new master cylinder or a new hydro boost or both.

I changed because of steering issues. When they go bad in the trucks you loose the ability to steer well while braking. It took care of the problem

Thanks Buddy.

@@DownNDirty_OffRoad strongly recommend everybody out there to get an OEM boost. Aftermarket didn't have the brake push rod, spring, and star looking retaining washer. Nobody sells em separate. Broke the old star washer Went OEM Also The one I worked on, the clip on the brake pedal was a whore to remove. There's a 10mm bolt which has plastic around it where it fits into the clip. DO NOT FUCKING REMOVE THE BOLT! Doing so ruins the clip but you won't know that until you try to drive it and the fucker falls off. Lastly, there is a brake pedal position sensor way up in there that you won't see at first. In 2 miles, I couldn't get up to 40mph. Didn't understand why it threw a check engine light. The truck thought I was standing on the brakes.

Raise the front of the vehicle only and turn the steering wheel lock to lock about 20 times it’ll get the air out. Not that hard.

Got to use the correct power steering fluid or it will take out the seal on your brake booster, just saying. happened on my 85 chevy.
