I see what it is now lol. That was funny tho, I thought you guys were crazy for a moment there LOL!

 

Can you do that on the passenger side too, when changing the wear sensor? I'm about to tackle this job for the first time myself on my 2014 s550 4matic instead of paying $2200 at my local dealer. I'll be using genuine MB parts but I don't need rotors on this pad change, they look perfect still.

Hi all,

Just curious how many miles you are getting in between pad/rotor changes for front brakes? And rear?

I know this varies greatly depending on the type of driving done and the style of driver you are…😀…curious the average.

Thank you all in advance,

Steve ( with a 2015 with only 37,000 miles )

 

@Jack Estes I don't know about the 2015, but on my 2019, the front pads were very easy. I just had to unscrew the brake fluid reservoir cap, jack up the car take off the wheel, knock out two pins, and undo a 13mm retaining bolt and the I was able to slip the old pads out and put new ones in. (When it came to changing the rotors, I wasn't able to leave the caliper on, it had to come off.)
For the wear sensor, it just slides into the pad, so you can slide it out and unplug it to do the job.

 

On my past MB cars (pre 2021) when I did the front pads, I was able to pull the old pads out easily using the same routine as above. However, on my 2021 E450, I found the pads were very snug, mind you they only had 2500kms on them and was just changing to ceramic pads. So I figured I would have to go thru the same procedure as in removing the rear pads whereby you must enter the Workshop Tools menu to electronically release the calipers.

 

Thank you @will_atl ! I think it'll be the same on my car. Just waiting on the parts now. I'm going to do the rears while I'm at it so boning up on the electronic procedure to release the rear calipers.

 

Make sure that the Parking brake isn't on when you try to electronically disengage the calipers (and chock the wheels), ask me how I know
I had also seen somewhere that having the hood/bonnet open can cause things not to function, but I can't be sure, per my point above!

I would suggest figuring out the electronic process before you get started, as it's probably easier to do at that time, rather than when you are dirty and sweating sitting in the drivers seat, just sayin'!

 

"electronic procedure to release the rear calipers", here's the instructs, only point missing in the instructs is remember to put wheel stops in front of front wheels
