Brake pads shifting in caliper

This is why alot of shops only install OEM pads, they always have proper tolerances which reduce issues like this.

Yes, stick with OEM....but better pads TRW TPC-1633 are a clean/quiet ceramic version of our dusty OEM pad.

For anyone else with this issue, the Centric rep that I spoke to had a suggestion for a temporary fix until they can design a proper fitting pad.

Basically you bend up the metal tab on the shim, insert a small piece of metal (the approx thickness of the amount the pad can move up and down) in between the shim and the backing plate. Then squeeze the tab back down to hold the metal piece in place. I even put some JB Weld in there to ensure it wouldn’t fall out.

It has significantly reduced the issue for me to the point where it is tolerable until I can find a more permanent solution.(y)

So many of the aftermarket brake pads for the PP brakes are like that. Why the hell don't they just make the pads bigger?

I also have the centric posi-quiet pads on PP brakes and get the direction change clunk. It's lessened over time and is likely related to crud build up between the caliper and pad. If a redesign comes out I'll pick up the new pads, but I like this compound enough and the issue isn't bad enough to switch back to OE. The super low dusting and linear pedal feel is fantastic for street driving.

If there was a ceramic OEM option I would of been all over it. I'll look into the TRW pads, thanks.
I’ve had two sets of front TRW pads (for PP / R brakes) and both have rattled like mad. Fine in the beginning but over a series of months they rattled any time I hit a bump. Extremely annoying. I switched to the isweep pads recently. Triple the price of TRW but I couldn’t take the noise so hopefully these remain quiet. If they do it will be well worth it.

That's odd, you would think the OEM manufacturer would be the perfect fit.
My TRW TPC-1633 brake pads are impressive and doing great. Even used them on the race track(autoX one lap timed) (not recommended but they did well, even over 1000*F...hence the bluing. I actually was shocked they didn't glaze over. For a daily, they're fantastic!

Agreed I scratched my head on it as well. Glad to hear you have had success!

My OEM pads shift in the carriers when the car changes direction backward/forward. Thought it was my imagination but I’m convinced that’s what’s going on. Sounds like the rears.

Manufacturing tolerance, probably. If they made the backing tolerance too tight, there's an off chance that the pad could get cocked in the bracket and not move properly. Knowing Toyota OEM pads myself, they have room to shift for that purpose. I ran Centrics in a vehicle I had before and they clattered at lower speeds. Wrote it off as part of the game with aftermarket pads.
