Hey guys, me again! I have an 2005 E320 cdi that recently started making a grinding noise on the driver side front when the brakes are applied. I removed the wheel and to my surprise I found that the upper bolt that mounts the caliper is missing. To my credit, I have never done the brakes on this car so I suspect that the previous owner may be responsible for this. I di not know if the bolt is stripped or if it was installed loosely but it needs replacing. I have searched the internet but couldn't come up with a spec on the bolt! Does anyone know what the diameter and length the replacement bolt may be?

Thanks as always

There are a couple of breaker yards in Atl area. Check them out or get one from the dealer.

Maybe take out the lower bolt and see if it will thread in and seat in the position of the upper bolt. If so, Bob's your uncle. You have the proper bolt to match either at a dealership or with the appropriate overall length, shank length, thread pitch, and grade from your hardware store of choice.
