Brake pads shifting in caliper

[Hyperlite]

Just did my brakes and installed Stoptech/Centric posi quiet pads. The brakes are performing well however I was getting a clunk noise when braking in reverse, and then again on first application after going forward. After inspection I found that the front pads are able to shift about a 1/4” up and down in the caliper carrier.

I found this thread which talks about a soft textured layer on some pads that prevent this noise...https://www.golfmk7.com/forums/index.php?threads/front-brake-noise.370379/

Thinking about trying to put some hi temp silicone on my pads to mimic the effect. (See pic)

Anybody have this issue before? Any suggestions on how to fix it other than buying new pads that are a better fit?

Just curious. Is there a set of anti rattle clips for the pads? Might help secure them better.

 

[Hyperlite]

The pads do have anti rattle clips and are installed properly. They stop the pad from rattling and moving forward and back and are working correctly. Unfortunately they don’t stop the pads from moving up and down.

I also thoroughly cleaned everything and greased the proper spots on install which isn’t helping my case here as it allows to the pad to move more freely.

i had the same problem with bosch front pads on my R. returned them and got oem pads. issue gone

Sounds like the pads are too short. Did you. Compare them to the OEM pads you replaced to be sure the dimensions are the same?

 

[Hyperlite]

I did not unfortunately. I had done research of other people using these pads with the right part number and assumed they were good to go. They fit, they’re just not a perfect fit. Lesson learned.

Only problem is I wanted to switch to a ceramic pad.

I had that issue with the TRW pads, but ironically, fixed the issue with the posi quiets. I didn’t have them on for that long but they were tight and quiet when I had them.

I get a little from my akebono pads when I switch from reverse to forward or the other way round but it's minor and doesn't bother me. Don't race etc but not a fan of the oem pads. Grabby or the system simply has too much assist for them.

Do you have the PP brakes? Maybe the fitment is better on non-PP vs PP?

Yes I have the Performance pack brakes.

I contacted Centric, confirmed that the part number and sent a video of the pad moving. This is the response I got..

“That is rather excessive. I have a few sets coming to my location from my main warehouse to test fit and see what’s going on. Standby”

I will update when I hear a response.

Same thing happens everytime I change rear pads, goes away after one track day. Probably packs brake dust in the gaps. Of course. No help if you don't track your car.

 

[Hyperlite]

Ya I don’t track and spent extra time cleaning and greasing the groves for maximum clanking noises

Just got a response back. They acknowledged that there is a problem, but don’t have a solution currently unfortunately.

“We’ve discovered a bit of a discrepancy…likely due to the thickness of the shim. The OE pad has what I would refer to as excessive slop in the caliper bracket as well, but the Posiquiet sample I checked has about an additional 0.5mm of clearance. We’ll be retooling the plate and shims to solve this. Unfortunately, I don’t have a solution for you right now. We’re probably 3-4 months out on getting this sorted out.”
