Caliper Bolts

[nova996]

I've seen a DIY write up that said you should replace the caliper bolts when the caliper is removed to replace rotors on a 996/Boxster.

But I went to a PCA tech session about brakes and they never mentioned this. Do these bolts needs to replaced every time they are removed?

Thanks!

The Porsche Workshop Manual states it like this (bolded where they bolded):

Fit new expanding spring, new retaining pin and new retainer (safety bracket). These parts are available as a repair set and must be "renewed" each time the pads are changed.

With that said... most folks don't. I am sure any car maker does this for liability reasons.

Personally, I check them for any signs of wear and replace them if there is any.

The caliper bolts should be replaced when changing rotors, because of their special stretching characteristics when tightened. They are relatively expensive, so for a discount try Suncoast Porsche.

The pad retaining hardware that Loren mentions need not be replaced at every pad change. Do as Loren says and check them for wear.
