CT944

Looking for some guidance, as I am an avid DIY'er. Looks like 2 large female hex bolts on top of caliper and 2 smaller male hex bolts on face of caliper need to be removed in order to replace pads and sensors. I have 75k miles on the Cayenne Turbo S and the PCCB pads are 30-40%, but want to replace them for peace of mind so not to potentially compromise the front rotors with worn pads. Any guidance would be appreciated.

Be so so careful - taking wheel off and touching that rotor with wheel is a multi thousand dollar mistake

I'd have dealer do it personally and I diy everything

Yes, I have swapped wheels plenty of times already and am very careful. The guide pin that is provided is a must use tool. Having a hard time finding anything on DIY PCCB on the web.

Shouldn't be any different than regular if you are comfortable doing it - every 20 or so wheel swaps on my track car I bang a rotor with the wheel everytime I thank god it's not a pccb Rear caliper has to come off, front if there is a center pin holding them in as seen on the outside of the caliper you just need to pull the pin out otherwise caliper comes off Usually it's 2 13mm hex bolts that hold them in Pair of pliers and a second set of hands helpful

Picked mine up - same front caliper and rotor as gt3 - you can use that diy if you want

Update: While having the dealer replace 2 rear tires, I had them install the front pads and sensors. Was only $240 for the labor, so pretty happy I had them do that and they said the rotors are like new still. Old pads had about 25% left, so wanted to swap them out for new ones before potentially damaging the rotors.

for future reference, you would unbolt the caliper from the car with those two top bolts, (if they are the same as the other brakes, they are a 14mm tri-square socket.), the bolts on the front do not come out. Once you get the caliper off of the rotor, you can pull the old pads out and put the new ones on. You also have to compress the pistons. They make a special tool for it, or you can use 2 big screwdrivers while the old pads are in and pry them between the pads and rotor before removing.

I must caveat this with never having changed pads on the car, I have always done it when I removed calipers for fresh powdercoating. (I am a professional powdercoater specializing in rebuilding calipers, although mostly retired from that now)

Not a very good idea if you have PCCB rotors and don't want to buy new ones.

yes, I guess thats only a good idea with steel rotors. Like I said, I usually do them off of the car completely
