The low brake pad warning light came on in my 300SDL yesterday, but i
am not sure it is working correctly. It flickers when i first apply
the brakes, then goes out while i am still braking. Other times it
will not come on until i have come to a complete stop and will stay on
while i am stopped, but if i let off the brake and roll forward the
light will not come on again when i re-apply the brake. It sometimes
flickers lightly when i am driving and not applying the brakes at all.
Is this a faulty reading by a sensor or bad light or something wrong
with the brake system?

Believe it or not, that is normal behaviour. The pad has worn down so that
the wear detector is *just* touching the disc, but it will be intermittent
as minor local variations in the disc surface sometimes mean that it will
not touch it, hence the light will not come on. Change the pads before you
get metal to metal contact. Ouch.
Mine was going to be in for service, but then when I called my dealer they
said it will cost me $419 to install 4 sets of pads, I called my independant
mechanic, and he said $247...so it looks like I'll be doing this myself...I
hate no having a lift, and I hate summer temps.
Out there every shopd just play safe, cause they have the responsibility
(legally) to make sure you drive in a safe vehicle. Of course this is an
excuse they rob you. If you have a c-class or e-class (looks similar to
c-class to me) buy a Haynes C-class repairing manual will help.
