Melted / overheated pad sensors

[DocSteve]

Hi,

My 2011 Cayman S has been in for a problem with the brake pad sensors at the rear. They started triggering the low warning light but in fact the pads are fine. No major problem but annoying so I asked Porsche to investigate. They say that the sensors appear to have been massively overheated and have failed. Initially they wanted to charge me but after a quick "discussion" they have replaced on warranty. They say they've never come across this problem and although the car has been tracked they say they wouldn't expect track use to do this.

Anyone had this issue before? I'm just wondering if there could be an underlying problem that hasn't been detected as yet.

Thanks
Steve

It may be because you have tracked the car and the rears have indeed got very hot which can happen if the traction control and stability control have been working overtime. The sensors are only cheap plastic.

Do yourself a favour and pri the sensors out of the pads and zip tie them out the way. Job done. If you regularly check your pads ( which you should if you track )then the sensors are surplus to requirements.

If the control systems on a Cayman S have been applying the brakes enough to melt the sensors then with all due respect I'd suggest some driver coaching. When driven well and smoothly the systems won't interfere at all, although if one can drive to a decent standard they should be switched off anyway.

Perhaps that should be on the OPC service menu...ahh Sir's brake sensors have melted, would you like the 1 hour, the half-day or the full-day driver coaching Sir?

Well I do switch the systems off when on track, although on a limit handling course it was still kicking in to some extent when being deliberately wild so perhaps that is where the damage was done if that is indeed the cause.

I'm not sure my driving need be attacked on the basis of my post!
