Clk brakes, disk and pads change

[Leabrooks]

Just a word of warning to fellow MB members and CLK owners, do not think it will be easy if your brakes are like mine, I found out the hard way today, seized and snapped bolts, corrosion, hours of hammering and drilling out of retaining bolts..what should've been an half hour job each side (front) ended up as a 6.5 hour job for the front pair, not helped by the torx bit snapping of in a seized disk retaining bolt (and too hard to drill out), absolute nightmare.
I think they must of been the original factory disks, 100k miles (and 10 years old) and the disks where completely seized on, the pads was easy. Oh and I spent an hour each side with a 4lb club hammer knocking the disks of their hub due to corrosion!... and yes all bolts/mating surfaes was soaked in WD 40 for a few hours before I started.
Seems like the previous owner swapped the pads regularly but never changed the disks (the outer flange on the worn disks had worn through the brake sensor wires above the embedded pad sensor itself triggering the OBD fault, the pads themselves where ok).
If anyone needs help if in the same situ, drop me a line.

discs

Lee i know how you feel .I have just finished,well all but one of my discs and pads. Mine were the same original discs 25 years old .In bad condition .Bottom bolts, i had to knock them out with a chissel .And not realy easy to torque back up to 115nm .Also after ordering new bolts mb sent screws.Told me they had modified them .All the grease cups for slider pins had perished.But the sliders were ok. Just sitting here looking at the weather ,and waiting for it to dry up so i can go out and finish the back passenger side disc.Thats after i have removed the old one.Hope you all fixed now with your brakes .

Yes i managed to sort the brakes, thanks, but needed Monday off work as I could hardly walk down the stairs, or stand up, and I'm a fit and healthy guy! Serious hard work! Next job is an exhaust swap tomorrow....fingers crossed it goes a bit easier than the disks!!

Glad you managed to get the job done and I would guess that a few choice words helped enormously

You don't say which WD40 product you used, but the original one isn't a penetrating oil, it's a Water Displacer; hence the WD and it is the 40th formula the guy tried. It mainly consists of fish oil.

They have now developed a penetrating oil. Best Penetrating Oil & Rust Inhibitor Spray | WD-40 Specialist

Just in case you weren't aware of these facts and so that you know for next time. (If you should have a similar problem again).
