Same thing happening to our '05 Odyssey. I had it at the dealer all day
Saturday, and they heard it, and 'deglazed' the pads, and still same
Then, they finally found a "Honda Tech Line Summary Article",
#ATS050707..."Grinding, Growling Noise from the Front Brakes - A grinding,
growling noise when applying moderate to hard pedal pressure at low speeds
is caused by the brake pad friction material. An improved material will
be announced in a forthcoming Service Bulletin."
In fact, while online this morning searching for this Tech Line site (did
not find), I found this forum and saw your msg. Sounds like your pads'
material already replaced with no help...disappointing.
Hopefully, we'll see a recall soon...
