98SBF

Hello all I have a 98 gs400 and I have a chirping noise coming from the ABS pump. Anyone have a fix for this or experience this yet

Thanks, Steven

never heard of chirps before. can you record it? if it's a never ending flatline noise, then it's the booster. (Very easy to replace) replace it with the 2001+ model if it's the brake booster.

I think its the ABS pump kicking in to maintain pressure. So im pretty sure im going to have to replace the entire brake booster/ABS system right there on the firewall.

Happens to me every so often.. then all of a sudden continuous beep like an alarm goes off and my vsc light comes on; ABS light; and the traction light all stay on only as long as the beep sound is on. And I hear that chirping sound like air is pumping?? I dunno but the brakes feel fine
