Sound from brakes when backing up after parking brake release?

[DennisW]

Hi,

Every time after I release the parking brake and start reversing, or maybe right when I start going forward, I hear what I can best describe as "linkage unlocking" from near my brake pedal.

It doesn't seem to have any negative effects and may well be normal, I am just wondering if anyone else has experienced this or may have an explanation?

Thanks,

Dennis.
