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!!
@@wolfsmane I can't say definitively as I didn't even try, but I don't think the playoff is worth the squeeze. Seals and so forth involved I'd think. Just ream that hole out and wa-la
@@DownNDirty_OffRoad i gut change mine but the brake pedal is all the way down. i get pressure only when i lift up the brake pedal. I don't know what i did wrong. Can you please give me an advise
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.
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.
changed my 03 gmc booster and it does shift out of park ok but the brakes seem like they are applied barely moves! Also the throw on the pedal is right there when you touch them with no to little play. Any ideas!
@@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.
I know this is late but the line on the driver side is a 15mm and the line on the passenger side is an 18mm. I managed to get away with being very careful and using the open end of my wrenches to break them loose and remove them
