Fold it down and remove the pads by pulling with a pair of pliers or a screwdriver.

I was wondering the process of changing the brakes on the Cayenne's, and what is required. I have installed full brake kits on other cars in the past as well as brake pad changes. The dealer said my Porsche brake pads needed to be replaced soon, and want to charge me $900 to do it. I said f*ck that I can do it myself. Is it true when replacing the pads, that every brake pad sensor wire needs to be changed? Also, my buddy told me it requires a special tool. Is this true? If so were can I order the tool from? Do I have to reset any thing in the menu of the car after the swap? I found the brakes, and sensors on advanced for a little over $200 for everything. I did use the search button, and could find anything. Thanks in advanced

Hi!
First, ask your official Porsche dealer if it´s possible to replace them without having a computer to tell the car...Most of the Porsche and VW need to be told via computer what is going to happen.
The new cars press the pads to the discs every now and then to keep the discs warm for NO FADING when it´s wet.

I don't know, those hands look pretty dirty to me after cleaning so much.

You have a Porsche and you're doing this yourself?!?

Haha, yeah right. Next time I´ll wear some gloves... My brother helped me taking the pics. Yes, I do ALL by myself, I am a former car mechanic. ;-)

NICE, but you seem to have missed a few important steps 1 loosen wheel nuts/studs before jacking 2 wash coating from disc with brake cleaner before fitting 3 remove cap from brakefluid resivoir and press pistons back into caliper,being careful not to overflow resivoir 4 apply some copper grease/high temp antiseize compound to the back of the pads and caliper where the pads move on it 5 before refitting wheel,gently pump the brake pedal without pressing all the way to the floor until it goes hard,then check that the disc is running freely,refit the wheel,lower jack and tighten wheel studs
