The ABS modulator makes noise periodicaly when engine is running, like every 15 mins or so. I understand it's normal for the ABS to make noise when the car first starts, but is it normal afterwards? I noticed this after I flushed the ABS and brake recently. I am not syaing it's not there before, I just didn't notice.

 

Check the fluid levels. My wife's Accord did that when it was low.

 

You may need to re-bleed it too.

 

The level is OK. I re-read the Helms and realize I probably need to re-bleed the thing.

 

Thats what I need to do.... to lazy to re-bleed it myself. h:
Makes like a .... wierd noise when I turn it on.

 

can someone tell me how to bleed the abs system???

 

I bled the air from the abs modulator today, lots air came out. Now the noise is entirely gone, even at start up (is this normal?? ).

To bleed the air out, just loosen the bleeder and start the engine, let the fluid run out thru a hose to a bottle, tighten the bleeder, shut the engine after the pump stops, repeat if necessary. Try to keep the level between min and max during the process. My car is a 97 GSR, so check the Helms if your have a different model, the procedure may be different.

 

OK I just tried turn the ignition to ON without actually start the engine, I can still hear the noise but it's a lot quiet now, kind of humming rather than buzz.
