Hi All,

My foot operated parking brake on my 14 plate E250 has gone faulty.
I can press it down and hear the ratchet but it comes straight back up.
Also the release handle is now just loose.
Anyone had this before?
Thanks
 
Many of us have. Either the end of 'Spring' has jumped out of 'Plastic lever', or 'Release spring' has come adrift. Or both.

The ratchet you hear serves no purpose other than to make noise. It plays no part in the parking brake's operation.
 
Hi - I'm new to this group and have just seen this thread.
This is interesting as my parking brake, although has not completely failed, sometimes needs a few tugs on the release handle while I pull up the foot brake with my foot.
I don't think any parts have come undone, maybe some lubrication is needed somewhere perhaps?
Does anyone have any experience of this please?
 
It appears to an old and common problem, just hook up the pedal and pull release at same time.
It come second nature after a short time

I would do the bracket where the cables all meet with a good spay of wd40 then the arms where cables go into wheels and then a smear of grease. Do you know if when you lift the back seat out of yours there’s an oval plate comes off to let you at the juntion where cables meet. , I can’t remember but maybe someone will soon. I remember doing this in the past and adjusting cables in there just can’t remember what models.
 
This fourum has lots of info, just search . Some MB's have an inspection hatch underneath the rear seat squab , some don't. This is the point where you can get to the (what I call the splitter cassette) and make adjustments and lubricate the action.

On one W203 C class I did the hatch was not visible as it had been covered with insulation from the factory , a stanley knife sorted that out.

It's not a great system , especially as the years go by and can be a bit of a pain to repair depending on your DIY skill level.

In post #2 the one marked 'spring' is the pedal return clock spring , the other return spring is underneath the car in not a nice place if you do not have the access plate inside the car.

Your problem is most likely in the foot pedal assemble as said in post #2 . But here are a few photos of mine for info . Yours might be slightly different underneath , but the pedal will most likely be the same.

The top red arrow in the schematic points to the end of the cable that terminates in the pull handle, it's obviously a lot longer than shown here.
