noisy braking on vesc4

Hi.

I run2 hubs hoverboard motors on a fsvesc4.2 .

They work very well with these parameters  :

141mOhms

299uH

18mWb

KP 0,3

KI 141

observer gain 2,9

Kv 18~20

but I have grunts when braking hard. it looks like the vesc, from a certain level of braking, has trouble applying the correct cutting to the windings. do you know which parameter to modify? Previously on a Lingyitek esc, these hubs did not brake much, but did not growl. on vesc they brake very well. but it makes noise.

braking at 3 and 8s
