HELP PLEASE: Does this sound like a rock stuck between the brake rotor and shield?

FlyFish · 05-28-2009, 11:13 PM

I searched the forum and found some discussion on this, but no definitive results. Please take a look at my quick video, is this the sound of a rock stuck between the driver's side rear brake rotor and the shield behind it? Sounds just like some members have described; a 'coke-can' rattle. But some of the conclusions weren't rocks. What the heck?????? At the end of the video has the most 'clanking'....

If it is a rock, how do I get it out of there???

Yep thats a stone, had the same thing twice myself....it will normally fall out by itself. Reversing seems to dislodge it sometimes.

Pretty unnerving sound--lets hope it goes away soon.

thanks

Maybe you should disassemble the caliper and rotor to take a look. It's not that big of a job. That would give you some peace of mind.

that sounds similar to what i experienced...mine wasnt a stone.

they said it had to do with a loose exhaust, etc: i typed it out for others who may have similar issues.
"end face of input flange has insufficient grease. ordered castrol optitemp ht1lf special grease. Lowered exhaust, removed heat shield. Marked drive shaft bolts, removed, greased and reinstalled drive shaft and exhaust"

I actually just had a similar sound in my car. I took a long commute from la to san dimas and I left this parking plaza to head back home and I noticed a similar sound minus the heavy rock sound that you have in your video. I basically had to hit my e-brake a few times while moving pretty hard and it went away. I wonder if the cold temperature might be the culprit. pretty wierd nonetheless never had that problem in any other car.
