I'm probably buying a very nice 91k mile 2005 Tahoe from a family member and I noticed a single "shudder" coming through the brake pedal every time I'm just starting to apply the brake. To me that's something to be fixed, because I just don't like anything but smoothness from the brakes in my vehicles. Then when I started exploring under the hood, I noticed the "Hydroboost" brake booster that uses power steering pump pressure for brake boost rather than engine vacuum.
I do have experience with Hydroboost, as it was there in my 1985 6.2 diesel Suburban of long ago. But why would Hydroboost be chosen on a mainstream 5.3 gas engine 2005 Tahoe? I probably won't want to try to convert it to vacuum boost. I hope the "shudder" can be cured by a new hydro booster and/or new PS pump.
Thanks,
Bry
