so , my rear pads need changing;

before I get my hands dirty, can anyone answer the following ?

1) What size / type is the calliper bolt - looks like a T55 star to me.

2) What is the tightening torque on this bolt on replacement ?

3) Will the dash warning of brake pad wear remove itself when I replace the wear indicators ?

hate paying garages to do jobs I can do myself... :)

There have been several excellent DIY brake replacement threads, most with the information you seek. "Search" is your friend............

I must be dumb... I searched the Panamera forums first and couldn't see any references to brake replacement & torque.

I'm guessing somewhere around 120ftlb for the rear calliper to hub bots...

OK - pads removed and replaced;

very straightforward job - 40 mins both sides

I've replaced the wear sensor that had been cut - the other side is fine

however, the 'brake worn' message on the display still remains - does this require a garage visit to turn off ?

I doubt Porsche changed their design from previous cars - so it should be just a loop circuit.

That is - the sensors are merely a wire that when broken trip the dash light.

A bad connection or a different sensor could still cause the open circuit. Worth inspecting all 4 brake sensors I think.

Hi Lauren;

thanks for the info - my thoughts too.

I did check the rear sensor circuit with a meter when I re-assembled - all was OK.

I never got chance to re-check though;

The car died spectacularly yesterday, and is currently sat in the local dealer having been recovered on a flat bad

All was going well - did a short 10 mile journey, parked up for 30 mins, got back to the car, restarted, drove off and had the following on dash messages

brake failure

PSM failure

check engine

4wd transmission failure

auto start stop deactivated

it also sounded rough, like it was only running on 2 cylinders !

So, as the car has Porsche warranty, I'm now waiting to hear what is wrong...

update in catastrophic failure - two coil packs failed !

great service from Porsche for resolution - all taken car of effortlessly and seamlessly

The brake warning light was a broken wire in a sensor - easy fix.

Going to swap the airfilter & new rear discs & front pads next...

does anyone else work on their cars here ?!

Not a lot of 970 info around just yet... but you are way high 63 ftlb. for rear caliper to wheel carrier.

But here you go...

Actually I have the complete workshop manual on the 970. PM or email me if interested

Here is the file for removing and replacing the rear brake pads on the 970.
