Ok so recently my left rear disc guard rotted and fell partially off rubbing on the inner dish, managed to get it broken off, fine. However my friend who had a look at it too noted a little tiny broken link thing, which he though might be a load sensor (he wasn't quite sure as he mentioned some can be electronic or not ... I can't mind the convo exactly, few weeks ago lol). He did say if it was what he thought it was if it thought the back was loaded too much it'd lock the brakes up...however I've no back seats or anything ever in the boot so prob be fine lol. He did say it looked as if it'd been broken for a while.
Gonna get Infiniti to check when there servicing it on the 18th but anyone clarify what this might be? Does the Z have load sensors at the back?
