I assume the booster quit from the feel, but there are notes of the magneti marelli pump assist failing and of the ABS pump itself failing?
That brake assist pump (camshaft driven device) makes a constant vacuum at idle.
No warning lights or CEL etc, heard a sound and next thing have to really leg hard to brake! I pulled the hard plastic hose and good suction from the engine - out of the assist pump it pulls down on my finger also (the red holder came out easily so need to repair) - grommet on the booster was part torn but no hissing sound at all - so I ordered a new grommet (wait til next wed for dealer...) but
Can it possibly be ABS pump (why would that be it - wouldnt the ABS light come on???) If not is there any way to tell if the booster is shot without removing it???
thanks!
