Brake pad spring clips...alignment issue

Just installing some track pads for next weekend. I was installing PFC08s with spring clips. I've never noticed before that the piston side pad's spring clips are not symmetric with the pad. The spring clips have three points in a triangle formation with a single rivet that allows them to spin on the backing plate.

Now if you install them with say the largest clip to the hub you get a certain alignment that allows the pad to rock and pivot in the carrier. If you take the clip and rotate 180 degrees, the pad will not rock and pivot in the carrier. WTF? Have you guys noticed this? Certainly not having the pad seated fully in the carrier will reduce the carriers ability to "lock" the pad in. Right?

Discuss please.

interesting wonder if this is the case with my pagid rears. having issue with pad rattle back there. will have to look into whether my clips can be rotated.

I have pad rattle too ... mainly when I reverse then go forward. you hear a slight clunk, like the pads move a little in the carrier/caliper. Sure it is this too ...

Good discussion topic ...



Things that make you go hhmmmm!

I've only dealt with 2 sets of PFC08 fronts and they both had loose clips on the piston side only. Initially I thought it was a bad set so I hammered them in but after the first track day they were loose again anyway. Not sure if this is by design but remember that until recently (a year or 2) all PFC track pads had no clips and were designed to float on the caliper, perhaps this is a continuation of this design with reduced ability to rattle. Just a theory.

I don't think I got this clear enough to you guys.

The piston side pad, it basically rotates around the pad. Depending on how you orient that clip determines how the pad will sit in the caliper carrier. I would think you'd want the pad making as much contact with the carrier as possible. When the clip is rotated around, it adjusts the location of the pad within the carrier.

Which way is the OEM clip oriented? I would think the PFC's should be installed the same way.

Yes, but I don't understand how it'd change the contact surface by rotating the clip, there's only 1 way to position the pad in the carrier, no? Is this what you're talking about?

Yep so if you take the first picture, then rotate the clip 180 degrees, you may find the pad doesn't sit as neatly in the carrier. It would kinda of rock and pivot on the pad.

I'm saying when you install the pads, check for rocking. If it does, take it out and rotate the clip and try again to compare my results.

But once you clip in the pad and put the caliper back on, how is that clip going to rotate? Unless its loose in the piston but I don't see the big deal since most track pads don't have that clip.

The clip won't rotate, it will hold the pad from flush and settled into the carrier. I'll take a video when I swap pads again.
