I have a 2008 Cayenne turbo with the red 368 mm Calipers (955 351 421 70). Since the top of the caliper is closed, it looks like I have to remove the caliper to replace the brake pads. 

I have not been able to find a DIY for these calipers. Is there anything special I need to do to get the brake pads out and replace the pad retaining spring?

Thanks in advance.

I was not able to pull a fault with my durametric, but was finally able to get to my local indy mechanical with the fault on. He found PDCC/ORS code 15627 Rear Axle Chamber 2 low pressure.

Any suggestions on what is causing the low pressure?

Thanks. I will get a durametric and turn on logging so that I can catch the fault when it occurs.

Once the weather gets cold outside, my multifunction display shows the fault "Warning Chassis System" almost on a daily basis. The fault always occurs when I am turning left and usually occurs within the first 10 minutes of driving. The fault stays on until I turn the car off, they it clears. The local Porsche dealer did not find any stored faults and the one local independent I stopped by with the fault showing could not find any faults using his code reader.

Does anyone have any suggestions? If I bring it to the dealer with the fault showing will they be able to determine the cause or do some faults that clear as soon as the condition clears.

I just sold my 996 and bought a Cayenne to haul the family. In the 996 manual said to use Optimoly TA on the wheel bolts and this made my frequent wheel changes easy, but I did not see anything in the Cayenne manual (I am still working my way through the 400 pages.)

Any suggestions?
