Brake pad indicator light just came on. So, I am now faced with the decision to change myself (hence the question), return to the dealer ($1900 plus tax), or find and aftermarket shop (???$).

I am pretty good with a wrench and have swapped out a few engines and tranny's back in the old days, so a brake pad replacement seems pretty simple. Any tips or advice? Is this a few hour job, or am I getting myself into something I am going to regret. My wife has been on me about the enviromental impact of 15 mph that this car gets, plus the overall cost to drive it, so a 2k brake job is going to set her over the edge.

I seem to remember a DIY step by step instruction that someone posted a while ago. Anyone have that link.

thanks for the help.

Check on Renntech.org, I think they have detailed directions there.

couldn't find/access them on Renntech. Maybe user error on my part.

lol... most brake pad changes are one bolt, swing a caliper up and slide the pads out...

OK, try this link. It's the Carrera procedure, but it's supposed to be pretty much the same, just with different part numbers for the Cayenne. You might have to sign up as a Renntech member to access this, if you aren't currently a member:

do a search and you will find plenty of info, pictures on my gallery

Did mine a few months ago and followed the procedure on Renntech.org. It was even easier than I thought I was planning on. Do it yourself and save your money.

It is a really easy job, about .75 hour the second time you do it about 90 mins the first time

How much more work to do rotors?

mudman2

More than double and you need a very good torque wrench. The tool for the calipers is available from the dealer or Snapon.

Brad have you the spec on that, I dont recall it ?

davidbrondstetter

thank you all for the information. Ordering my pads now.

You'll want to check those rotors with a micrometer. Every time I've put pads on a Cayenne (any model), the rotors have been worn very close to their minimum thickness and have required replacement at the same time.

Bummer, I know.

Oh, and caliper bolt torque is 200 ft./lbs. The bolts should be replaced.

davidbrondstetter

alright, now I'm confused. It looks like the brake pad change requires a standard wrench only from MudMan2's pictures, and the caliper does not need to be removed? So, if I am just changing brakes, is that correct that I do not need a special tool? I have a fairly extenisive toolkit and a torque wrench.

Also, I am aware that I will need the new sensors as my light went on, but do I need anything else light new clips, or bolts or a dampner like they mention on the Carrera procedure. Thanks

If you're just doing pads, all you'll need is a wrench for the 13mm (I think) bolt that holds the pin in. There are no separate pad dampers on the Cayenne brakes.

You'll also need to retract the pistons into the calipers, which is easier with the pads still installed. I use a pair of channel-lock pliers to squeeze the pad backing plates against the caliper. I recommend a shop rag to avoid marring the finish on the caliper when you are doing this.

Most awesome. That is what I will do then. You all have been very helpful.

Thanks
