Title: Mercedes C180K rear pad replacement
Post by: minifreek on 15 June 2015, 11:07:38
My uncle knobhead has asked me if I will replace the front and rear brake pads on his Merc C180K, Iv said as long as he pays for the parts then no problem.... which he has done... :y

Im just thinking, do the rear calipers need a rewind tool...? or can I just use my trusty method of clamp and squeeze....?

If I need to buy the rewind tool thats not a problem I'll just get the cash off my Uncle for doing the job :)

I replaced the front discs about 18 months ago, but I advised him at the time to get new pads for it sooner rather than later... he'snow complained about the brake warning keeps flashing up on the dash....  :-X :-\ ::)

Matt, you may be lucky and just require a manual rewind tool. (eBay kits are £15-25 to cover most cars).

The problem is, if it's not a manual job (you'll need to google to confirm). Some modern cars require a computer to wind the calipers back, I jest you not. If it is one of these, be careful, as computer connected and ignition on lead to a flat battery. The default setting on the handbrake (via calipers) is ON. So battery goes flat, calipers clamp on to potentially nothing (discs & pads removed) and pop the piston out.

Probably depends how old the C180 is. A mid 90,s example should be straightforward. I dread to think of what the procedure might be on a current model.

Most Mercs have seperate handbrake in the form of brake shoes inside the rear disc/drum

The handbrake on his motor is initially foot operated and then has an electronic release on it...

I don't know what year it is as its on a private plate.... think its a 2002 model...?

Iv heard about needing a computer to connect to the car to rewind the pistons... thanks Dave :y

Just had a quick gander on here via google and it came up with this link : http://forums.mercedesclub.org.uk/showthread.php?t=90922

Seems the HB is manually adjustable so might just need a rewind tool for the caliper....

And to replace the rear pads is quite straightforward it seems :)

You may remember my post about my first encounter with those electric calipers  ::)

30 mins of trying to wind it back and then was told 'oh yeah, shoulda mentioned they need the diag tool to wind them back'  ::)

Well job done, was easy TBH - would've been easier if the correct front pads had been sent. The rears was very easy to do...

seems my uncle uses his brakes a little too much as the front discs where new about 2 years ago (I know, I fitted them) and they both need replacing because of very bad scoring on the insides of both of them....

Hope it passes its MoT today.... gonna need a bloody good clean before it does go, its like a ruddy automotive ashtray/wheely bin inside his car...

sorry I disagree  I think you are to blame
you never fit old pads to new discs its bad pratice[as you have now found out and your uncle is paying for the mistake] as they have worn to the old discs.

I should have said that I fitted new pads at the same time too...

I also fitted 2 new front springs, which was a pig of a job to do as the front springs on the C180K are oppsing huge...

ah that's different then,but its not what you said in your first post.
you said something along the lines

"I replaced the discs 18 months ago but I advised him at the time to get new pads sooner rather than later"

I did replace the pads for him about a week after replaceing the discs and springs, my wife has just reminded me as she remembers it was a week after valentines day (did the discs and springs on valentines day, wife wasnt best pleased TBH) ...

Anyhoo, he needs the front discs replaceing now...

I know the handbrake shoes will be perfectly OK as he doesn't use it, just leaves the car in park. The handbrake is 1 of those foot operated jobs, he has a faulty left leg so tends not to use the handbrake...

On an Auto with a heavy right foot, discs tend to last around 15k anyway.  Shit discs, well, you can halve that!

Nothing unusual about changing discs every 18 months.
