Good input. Yes I also feel the same vibrations thru the brake pedal but this doesn't really bother me because my foot is not on the brake for any long period of driving time and there's no vibration at a stop light.
Another reason I want to try and isolate the pedal is because of the knocking that is also being transmited thru the pedal. This is a different problem that has been discussed in other
threads. In summary, I get a knocking noise and feeling sometimes. It's weird because it doesn't happen all the time. For example on short trips in the morning or on my way home. When it starts knocking you can hear it with your ears, feel the knocking in all the pedals and even the steering wheel. I brought it in to the dealer twice and they claim they cannot reproduce it or hear anything.
Every time it has happened and I have had a passenger with me I ask them "do you hear that knocking noise", and everyone says yes. I now have a better handle on what it takes to make the noise louder when it's occuring. The dealer has offered to have a tech drive with me at any time. However it has been 2 weeks since that offer and I have only had the knocking issue occur on weekends or when I didn't have time to spend at the dealership.
Btw, if you review the
knocking thread, other H3 owners responded that they had the same issue and some of them even described it better than me. So my knocking/vibration issue is not limited to my particular H3. Sometimes I feel quite frustrated because these are little stupid things but they are driving me nuts, like a splinter in my finger. When my H3 starts making the knocking noise and thumping against my foot I just want to drive it off the overpass. These issues are ruining what should be a great experience with my new Hummer. (not to mention the wind noise from the marker lights).
