Thread: noise from abs module

Sorry if this has been posted before, did a search but couldn't find what i was after.

Just recently I had my brakes flushed, now it seems occasionally that straight after applying the brakes a whirring noise seems to be coming from the abs module for a couple of seconds then stops.
The problem lasted for one 20 min trip then went, and another time 5 mins and then went away.
Could this be a symptom of having air in the system or something worse?


Thanks

Yep,my thoughts also, fluid level is fine,i'm really wanting to here that its air in the system and nothing worse
