help, strong noise when ABS engage during startup

[mikevin]

Hello po,

Ask ko lang if may idea kayo or experience, kung bakit kung nageengage ung ABS ko during startup(ABS engage ONCE every startup kapag nareach around 10kph).

Maingay ung tunog for 1-2seconds, tapos ramdam sa brake pedal na nag seself-test ung ABS. Parang gears na umiikot na hindi kumakapit.

After tumunog ung noise, unlimited mileage na, wala nang tunog.

Suspect ko ABS, kasi sabay siya sa self-test ng brake pedals.

Pero bakit kaya naka depende sa angle ng tires ko ung lakas ng tunog?

* Have my front abs sensors cleaned, walang improvement at wala naman dumi.
