I have a 1974 MB 240D, and there's an odd sound coming from the rear -
while the wheels are spinning (in gear or not), it sounds like
something is rubbing against a moving part in the rear. The sound
becomes more frequent at higher speeds (duh), but I don't know enough
about what's back there to determine what's going on.
Also, right now the parking brake is really loose - it sometimes
doesn't catch even with the parking brake pedal to the floor. About a
month ago, I cranked the star wheels on the rear wheels (parking brake
adjustments?) to their maximum tightness, so that leads me to believe
that either the parking brake cables are shot, or the brake shoes
themselves are worn out. Is replacing parking brake parts a
relatively easy DIY project, or should I take it somewhere and have it
done? Thanks people.
well sounds like pads need to be replaced
there is also a center screw for cable adjustement beneath the car, in the
back, above the cardan axle
this is where it splits into the cables to both sides
this also compensates cable lengthening through years and usage
there is a standard procedure in adjusting the parking brakes, I don't like
to do it..cause it's not easy to hit exactly the point where break power is
max and pads not draging
if you get a repair kit for the drumbrakes...it not only includes the pads,
but also the retaining springs and maybe eben the star excenter.
its a fairly easy job, but requires some patience with setting up pads and
their retaining springs.
the sound u are mentioning is most likely a pad touching the drum cause u
fastened the "star" too hard
that's how I do it:
jack up back of car with both rear wheels off the ground
release parking brake
loosen the centre bolt underneath the car all the way, where cable split
loosen one bolt on each rear wheel
tightend the "star" on both wheels, until can't be turned by hand
go back 1 or 2 notches
wheels should be able to turn by hand with ease now (disregarding transaxle
resistance, of course)
now srew in centre bolt under car until cables are pretty tight...not
applying break power though
now set parking break to notsch 2 or 3...u should allready feel breaking
power at the rear and not be able to turn the wheels by hand anymore
u will probably not be able to get it all even...but there should be
allready a difference
if not....chance pads...then adjust again
ok...hope u were able to follow most of this :O)
