BREAKING PROBLEMS

1999 Mercedes Benz A140 • 2WD Manual • 18,000 miles

Hi,
Whenever I break and wish to stop the ABS kicks in and I can hear/feel the clicking and the car keeps going. It does it at speeds of 30mph or more and even if I break gently wishing to stop at traffic lights. This has been doing it in all conditions and even in dry perfect roads. I have a Mercedes A140, age 2008

You should have an ABS light on the dash anytime this system isn't functioning correctly. Start by having the computer scanned for the codes.

The ABS system is meant to pulse when it's activated. If it's activating for no reason, then one/more of the sensors in that system is sending the computer false data to do so. A scanner is the best way to find this, but a trained technician with the know how can find the problem with a voltmeter/scopemeter.
