I recently changed the rear brake pads on my 2015 C63S and thought I'd share my findings on part numbers, tools & my procedure. I can't guarantee the accuracy of these instructions but believe them to be accurate. Hope they help someone out!

Very detailed write up. Thank you!

Great job

Great write-up!

One question: in Step 10, you say "jack using central jack position". I wasn't aware there WAS a central jack position, and the Owner's Manual doesn't make note of it. Where is this central jack position?

I only did the rear pads this time and I didn't check to see if there was a central point in the front but I thought that during my research I had seen that there was one. The next time I'm under there I'll see if there is one and post what I find.

Two thumbs up to a great write-up!

Hi BD-C63,
Finally changed the pads today.
I would like to thank you from the bottom of my heart for the great helpful article.
It took about three goes to have the brake release, but, all else was flawless.

One comment, but, my lug nuts were actually 17mm not 18.

Again, thank you very much and please whenever you do some repairs/replacements; please let us know.

Cheers,
Mark

Just did my rear brakes using this guide, great job OP! Only change I'd make is to highlight how you need to grab the inner nut with pliers/Vicegrips/wrench (20mm?)/etc. I know you call it out in your write-up, but I somehow glossed over how essential it is, as otherwise the caliper bolts just turn and turn while trying to remove them.

Also, thought I'd add: I did this work because the dealer told me I needed rear brakes (pads/rotors) at my first B service (20k). I declined (because ~$900) and let them go until 22k (today). After I pulled off the first rotor, I threw a set of micrometer calipers on them and found they were down 0.5mm vs the new ones. I had zero scoring, and no ridge at the edge. Personally, I'd let them go for another 20k and not worry about them. The pads themselves were definitely worn though; I probably had 5k left tops before I hit the wear limit sensor. Though I bought the OEM discs from FCP Euro, so a lifetime guarantee is nice to have. YMMV.

I installed Porterfield pads, I'm expecting much less brake dust AND squealing.

Hi,
Keep us posted as to how you are finding the Porterfield pads

Will do!

Go to Home Depot and get a squeeze grip. They're in the tool isle and work like a charm. The Two pack is maybe 14 bucks

Here you go

Good information in this thread. I'm accumulating information on DIY work for this car as I've got one on order. I come from the VAG world where there is a ton of DIY guides and am a little surprised there are so few for this platform.

Could some of these get 'stickied' to the top?

Thank you! will use this for my GLS63.

I am about to install both front and rear brake rotors/pads on my W205 C63S. What are the torque specs you guys used when you reinstalled the parts? I've searched and couldn't find the answer.
