A month ago the brakes on my 1999 E240 have begun to squeal on gentle
braking. The car has passed all the manufacturer's maintenance
schedules (the last one, 8.000 Km -5,000 miles- ago). There are no
brake wear lights on and the car brakes perfectly except for the
occasional noise. I usually drive "planning ahead" and tend to brake
very gently whenever I can. The rotors do not seem grooved but I can
feel a small "lip" of about half a millimeter at the edge. The pads
are OEM and now have 50.000 Km -31,000 miles-. I do not drive the car
outside paved roads, and it is used mostly on the highway.
If the pads are worn, shouldn't there be a warning light on? I am a
little weary of taking this to MB, as I fear that they are prone to
taking the easy way out: changing rotors and pads, whether I need it
Thanks for your advice
This could just be vibration. Inspect the pads for wear.
If they look good. Don't worry about the squeak. If it really bother
you, you can pull the pads off and reinstall them with some
"anti-squeal" stuff from the autoparts store which basically is like a
glue that cements the pads to the pistons, so they can't vibrate...
Thank you very much, Martin. I will have a look at the pads. The
squeal does bother me, but I do not think I am up to removing the
calipers and pads myself. A slip of a hammer or a wrench could keep me
out of business for weeks (I am a surgeon). I think I will just take
the car to any fast mechanical shop. have them remove the wheels and
look to see how much pad lining is left. It has rained a lot since I
dared to remove the head of my dear Mini and polish the valve seats. I
was under the impression that brake paste was more of a lubricant than
a glue, though.
I had heard that some hard braking could get rid of brake squeal
sometimes, and also that an excessively gentle use of the brakes could
glaze the pads and promote squealing, but then these could just be
My understanding is that squeal comes from dust. I have had it to on a
newish car; the Merc dealership applies some paste but they did say that it
was not a permanent solution. I have learnt not to be bothered by a bit of
squeal; pads are not necessarily worn.
