Short Back story: I bought a Honda Ridgeline Second generation (2016 - current), 11,000 miles from the dealer, with a state inspection performed on the purchase date. The next day and a maybe 35 miles later...
Suddenly there is a loud noise coming from the back, it sounds like I am dragging a tin can. There is nothing visibly wrong, extensive safety check completed on road side. I am with in 2 miles of the dealers, so I return. (slightly stressed and anxious)
I just traded in a Second generation (2009–2015), with 100,000 miles that I put on myself, without ever hearing anything like this
The dealer identified the sound immediately as rock in the rear disk. He took it in the shop and in 5 minutes the sound was gone, and he had a tiny pebble that they removed without tools. Apparently it gets into a hollow on the disk brake like rocks used to do on hubcaps.
I googled around and found a couple of similar events to other Ridgelines in the same generation. I also found that it happens on other cars as well, some being more prone to it then others.
- Is there any danger from driving with this rock in there, or is just noise? I assume like a rock in your hubcap or tire tread, annoying but not life threatening.
- If I leave it in there, how long before it comes out on it's own?
- Is there any physical reasonable vehicle modifications that can lower the probability of this occurring? (i.e. a special shield)
This is distinicatly different then the related quesion rock groove on brake rotor OK? where the rock is between the pad and the disk.
