Pad shifting/moving/knocking on BRZ PP
 

Just curious to see if ANYONE had/has any problem with the Brembos on the BRZ. I changed my pads for a HPDE event using Endless ME20. After the event I changed back to the stock Brembo Pads. After a second HPDE, I did the same thing changing pads from the Endless ME20 to stock Brembo pads. I cleaned everything up and now have noticed my pads are moving/shifting or even knocking. Ive checked , triple checked and everything is secure (There isn't much to installing pads on these calipers.)As the car moves forward, the pads make a slapping or knocking sound initially. When the brakes are applied, there is no noise. If I reverse, the pads make a slapping/shifting/knocking noise again. I figured it would have gone away but its been a week of just daily driving and it continues to make the noise.

No problems with mine but I haven’t touched them since new.
