Brake CLACK!

mine does this! started after my first DIY brake pad change. everything went back in with ease and no "issues" were encountered, but if I go from Reverse to Drive, the very first time I brake (hard or soft, doesn't matter), it makes a noticeable "click" as if the pads are seating against the rotor or something. Any time after that there's no noise.

What causes this? I've been too lazy to check myself. My brake functionality doesn't appear to be affected at all. Still stops on a dime.

What I've seen typically is there are brake pucks or adhesive disc called "damping shims" that are attached to your original pads. When you removed the pads they will sometimes stay in the caliper cup and more often then not they come out with the pads as they have an adhesive backing. These "pucks" do not allow the pads to shift back and forth in the caliper. Just a thought as I have performed many brake services and most recent being a 993 in which I remember them coming off rather hard.

That's a really helpful post for your 1st or 2nd.
If they're all this good, you'll be a legend by post 100!

I dont know about that . But Im almost positive the noise your hearing is the brake pad shifting back and forth in the caliper, thus making the audible click when going from reverse to drive or drive to reverse. Check it out, see if those damping shims are in there if not, I'm going to be pulling my 986 into the shop today and ill take a look as I'm still on the original pads. If mine are there I'll take some pics.

I've had this happen on and off for years now. Never could find a reason. Caliper is tight...
