Hi just wondering i have read that Porsche recomends not to re-use the caliper bolts , do you guys actually change them or re-use them also if the brake sensors have not come on can they also be re-used thanks

You should be able to reuse them as long as the bolts are not scored or seized/binding. Just make sure to apply a caliper pin lube such as permatex or loctite. The brake sensor should be replaced as the metal material wears with use until it breaks. Also the wire itself becomes very fragile and can break while transferring it to the new brake pads.

I can't comment on the bolts, but I can tell you the sensors are very difficult to remove without breaking them. Even if they haven't started to wear at all, they get very brittle from the heat. I attempted to re-use them when I did the brakes on the Cayenne. And I found myself at the parts department mid way through the brake job because the sensors were crumbling when I tried to pull them out.

great to know , im just learning as much as i can have never done brakes but im going to take the plunge not for cost but for the satisfaction of doing it myself .

I say change the bolts as recommended. They're only $4 each. Just ask yourself whether your life is worth that much money?

louie007

was not aware if the price , at $ 4 yes i agree is that a dealer items because the online store im ordering the rotors pads ect they dont have caliper bolts .

you can reuse the bolts that hold the calipers on. But you cannot reuse the bolts that hold the caliper togather. you are not supposed to ever take the caliper apart

I'm interested to know how you came to this conclusion when Porsche recommends the opposite?

At $32 it's hard to argue against changing them. When you look at the total cost of a track weekend it is a small item.

Before you reuse caliper bolts, read through this thread

I generally replace mine, but admittedly not every single time. Also, I change pads on the front without removing the calipers, so I don't replace the bots since I don't take them out. I will soon need new rotors, so I will replace the bolts at that time.

I track my car frequently so I removed my pad sensors and tied up the wires, so I can't comment on this. I know they were very hard to remove without breaking, but I admittedly wasn't really trying.

Good info there. I know the bolts would stretch but I didn't know the threads on the aluminum upright are that vulnerable.
