E39 screeching sound from wheel

[nickchin1308 0]

Today I realised, the rear driver side wheel has started making a screeching sound (as if a stone is scratching something).

The sound can only be heard if the windows are down and when driving at parking speeds.

Looked at the wheel and brake area roughly and everything looks okay but I am no expert.

Anyone had this problem before and know how to solve this?

Bound to be a stone wedged between the disc & backing plate.

Otherwise - worn /low pad - the low pad sensors are on L/H front & R/H rear

Cheers, was just googling about this and it looks like the stone problem is quite common for the E39.

No low brake pad level indicator has appeared on the OBC yet tho.

Not wrong on the stone problem being common in E39's - when running on 18's anyway. Always been the fronts on ours & nearly always has involved removing the wheel to fix!

Have had a few stones wedged in between the disc and backing plate over the years with my e39's. I usually just give the backing a plate a smack on it's backside with my hand and it seems to loosen the offending stone.
