Strange noise when braking

[Ludeem1]

Last week I was doing some datalogs and when I came to a stop sign I heard this noise and it went away as I started to drive away. I thought it was the brakes as I got them hot stopping from 90mph very quickly. Yesterday I heard it again, I noticed it happens only when stopping from a high rate of speed very quickly. There’s no noises under normal driving conditions. I checked the torque on my caliper mounts (Tarox BBK) wheel Torque and inspected the suspension. Everything seems ok. I used 2 different brake pads and same issue. Any ideas ?

I would clean and re grease any moving parts. Could just be some small debris and something is dry. I would take pads out, spray, wipe and clean any parts that move. Then I would lay some grease on the back of the brake pads as well as anywhere else those pads may be sliding on.
