Parking brake pedal not fully returning up

[d215yq]

Hi all,

Next on the to do list of addressing little annoying things, parking brake mechanism releases with the pedal not fully coming up so it a) feels loose once released and b) lights the red light on the dash. Happens more so when cold, once warmed up if it's helped up it will clear and stay just high enough not to activate the light.

Now I know there is some PITA way of adjusting the handbrake at each wheel but I don't think I need to do this as the handbrake workls perfectly and holds the car on a very steep hill and releases fine

Is there a seperate mechanism somewhere for the pedal. I remember asking here and trying to take the pedal off/see the pedal mechanism but what's on the car looked nothign like what was posted up here and I can't find any screw to turn/way to adjust it (or even remove it) from the car.

If there's no trick I'll simply attach a biro spring to the top of the pedal lever and attach the other end to something above...but be good to know if there's somethign easy I can do to fix it.

Under the rear seat area is a cover which can be removed to expose the cable linkage. Sounds like it needs some lubrication.

Thanks, I'll silicon grease it. I'm assuming you mean it's accessed from under the car, not from in the car under the rear seat? I know most cars are adjusted from inside but I think Mercedes are different?

Inside the car under the rear seat.

Any idea how to lubricant it on a w212.
When ever I release the parking brake I need to put my foot under the pedal to release it fully and stop the warning light from flashing up.

As above.

Mine does this first thing in the morning whenever cold. I'm assuming that the rear seats have to removed to get to this to lubricate?

Correct. Lift the lower squab and the access panel is below.

I found this video, is this what I'm supposed to be lubricating (probably easier to crawl under with the spray gun than remove the rear seat as I can't find any obvious bolts to remove the rear seat)? Or is there an other additonal mechanism under the seat?

Found a great Youtube video explaining rear seat removal. Just did mine, the front clips were easy, the rear bit was a little tough.

Ta daaaaaaa

Thanks, got there in the end, just need to find the areas to grease and go from there. I have some grease in the garage.

Need to do some more research, lifted the panels and not sure what I'm looking at?

Over the transmission tunnel or next to it.

In some older cars there does seem to be an access panel that you can remove with four screws, the only thing I can see is something held in place by two larger bolts, not sure if I should remove this bit?

This is for the W203 yours may be similar.

Thanks for the help with this, the car is going in for the B service at the end of April, I will as if this is something they can add on then.

No don't remove it!

Yep that's what my document says. A panel like that but it may only be on earlier models. Certainly my 202, 203 and 129 all have/had it and the document says 210 as well.
