If its coming from the right front corner then it sounds like it is the ABS actuator motor and it should not be activating like that unless you actually engage the ABS system. And to do that you have to be going I think above 15MPH or so and then if you try to stop quickly and you have limited traction or loose gravel or the likes it can trigger the ABS to go active. There could be other things causing this to occur but by all means get it looked at as it should not be occuring under normal braking conditions.

Maybe some others will chime in here with additional info. Hope this helps.
