Pad Shift...

I've had pad shift on one or two of our cars. I'm not sure if "mr. flying s2000" is describing what Honda is referring to. Honda interpets Pad Shift as the pad moving parallel to the surface of the roter "side to side". As it shifts, it "clicks" against the sides of the calipers. When you apply the brake, the pad moves inward to clamp the roter (normal), once it grabs. the rotation of the diec moves the pad into the caliper guides. MDXs are notorious for this since they have the most play between the the pad and caliper.
2) I randomly happened across an article on the maintenance wall while waiting - it was a directive to all mechanics to inform customers of a proprietary characteristic clicking that can come from pad shifting on all Hondas (except a few, but can't remember).

My theory is purely a guess. If I were in his situation, I'd just take off the tires and start checking all the bolts. Maybe buy some new pads. They're cheap enough. Perhaps the previous owner put some cheap pads just to turn the car in.

I mean some shims on the sides. To effectively make the pad slightly larger, not thicker. I have a buddy who works in a machine shop, so maybe I can get him to slice me some aluminum or something.
Honda already replaced all pads, and even the rear calipers (they were sticking) not but a month ago. I will run a general troubleshoot this weekend by taking brakes apart and checking for shift. Then I will post my findings and possibly brainstorm for some solutions.

I have the same clicking noise, only when the car goes from a forward direction to a backward direction, like backing out aof a parking space then going forward. Bugs me too but there doesn't seem to be anything wrong with it. I just had the brakes bled and had the Super Blue racing fluid put in at FC 05. The clicking is still there but I seem to have great stopping power. Just one of those things.

Sounds like the original poster has pad shift. Not a big deal and very normal. Not sure why some people think otherwise...
meter.Dustin - Nah, I think I can get it. Should only take like an hour of so for the whole thing. Just going to try and confirm that it is indeed pad shift and that the dealer is not using it as a scape goat for their incompetence. You also have not seen the car since any of the mods....I now have an INJEN CAI, Comptech exhaust, full audio (still need amp for cabin), and Rick's console cover and shift boot (red / back two-tone). Shoot me a PM if you want to see it.

It sounds like a few people are describing different noises.
A sharp pinging noise can be heard when changing directions from both your wheel hub and possibly from your diff as well. These are two of the more common rear end sounds that this car tends to make. The brake system on the S is extremely simple in design and should be easy to trouble shoot for a problem like the one mentioned in the orginal post.
Front end noises tend to be a little more tricky. The sway bar can clunk, but this is more typical of the aftermarket bars and generally should happen when turning the wheel.
A front end clunk which I experienced and have not read about otherwise can be related to the alignment adjustment bolt on the lower control arm. This bolt has two pieces which must be tightened in order. If just the upper adjustment bolt is tightened it may result in a clunk.
A final theory I have heard for front end clunks relates to the upper control arms. As many of us have read the welds on the mounts of the upper control arm have come loose under high stress. It's possible that a clunk may result when the upper control arm places stress on its mount point and the metal at the base of this mount flexes with a popping sound. In a fashion I have referred to as "tin canning".

ImportSport - Thanks for the input, but I am pretty sure its coming from the brakes, as it ONLY happens now when brakes are applied. I took a look at the brake assembly last night, and it should not be hard to troubleshoot, as you stated. I will do it this weekend and post my findings. I started this thread to see if anyone else had a similar problem, and Honda had fixed it. Honda just kind of blew me off.
