I have been replacing the front discs on my XKRS
I took the complete calliper off including the calliper mounting bracket by removing the two calliper retainer bolts.
I fitted the new discs and slid the calliper over the new disc after compressing the piston with calliper compression tool.
I have noticed this part on the floor of the front wheel arch
Any idea as to where it could be from ?
is it part of the braking calliper system or is it from something completely different ?
I need to put my mind at rest with something as important as XKRS brakes.
Any ideas would be most appreciated
Thanks

 

I realize now must be from the brake sensor that must have been caught during removal of caliper
