Parking Brake Shoes Detatched

[moj91]

Good Afternoon all -

My W204 went for its MOT yesterday and failed (which was a surprise) as the O/S parking brake was not supposedly providing the correct force.

(Not that I could tell because the parking brake is naff anyway!)

The garage has confirmed that the cable is actuating, but having then removed the disc, it would appear that the pads have detached themselves from the shoes!? And have little to no pad left.

The other side appears to be fine.

The rear pads and discs were changed about 18 months ago, the handbrake was set up again/adjusted seemingly well in that it bit well but also released seemingly fine.

Has this happened to anyone else?? Anything we need to be changing/adjusting in addition to stop this happening again?

Cheers!

Had this happen on our w203. On that one the shoes rotated round and jammed the wheel solid causing a most spectacular sudden stop in a cloud of tyre smoke in the midst of a sleepy village....

In my case I tracked it down to an other half who hadn't properly released the parking brake then driven about a mile with it partially on (she says she never heard the bonging noise that results from such an activity!).
Replaced and no furthedr issues.

Happened on my car too...just had the shoes replaced.

had it on the 203. more than once. whatever they use to 'glue' the friction material to the metal part of the shoe seemed to gradually fail (dissolve or whatever) and that would be the end result. I blame it on moisture getting in (its in the air, you cant stop it) and dissolving the adhesive as the handbrake set-up never gets hot enough to properly dry out, unlike the rest of the brake system. no clue if my theory is correct, but it does make some degree of sense (to me at least)
