Hey guys, is this normal for aftermarket brake pads? I just did brakes and rotors on my E350 and the inner pad has been rattling. Check out my short video above. Is the design of the pads I got the issue: aftermarket quality being less than ideal, or is this just how it has to be? Seriously hope not cause it’s so annoying to have to hear the rattling.
is there a brand of brakes that doesn’t have this issue someone would recommend.
These simple calipers are easily trouble free. When you let go the brake pedal the pressure relief allows the large piston to move back a little. The non-piston side has more difficulties getting freed. Caliper has to readily slide on somewhat parallel guides. So pad pretty much stays in contact of moving disc and caliper backing.
Piston side:
It may not be that side you hear rattling. It looks like it already has high temp lube between backing and piston, a good thing to prevent noise. Adhesive shims can serve that purpose.
Caliper side... troublesome:
The opposite pad may be vibrating against the caliper. Lube that backing a little where caliper contacts pad OR glue the pad to the caliper.
What favorite lube did you apply to your sliding pins: silicone ?

I did the brakes and rotors on my S212 at the beginning of the summer. I ordered the Akebono Ceramic pads and Zimmermann rotors from FCP Euro. I didn't have the play that you have on the the pad that clips into the piston. As I recall, the pad clipped in and there was no movement at all.

I’d used some copper anti-seize, but will take you recommendations for a silicone lube that you’ve had success with? To be honest, I should have replaced the slide pins, and will order replacements now. There was some rust on one of them

thank you @Raj1471 , I’ll replace my slide pins and use some better lube and the fcp pads will be the next option. If they work and lifetime replacement to boot: what’s not to love about fcp euro
That clip which is riveted in should not have play like that. Atleast my stock pads didnt and the brembo pads I replaced them with did not either. Once they are installed and you put the anti rattle clipes (the long ones) back on it shouldnt have any rattle like that.
I was missing one of the rear anti rattle clips I found out when I did the job and it was the cause of a rattle I heard going over bumps. New ones are like $8 I think.

I don't know about anti-seize on slide pins. Isn't it too viscous?
You really want no petroleum involved there and a high-temp lubricant that helps slide without evaporating like the OEM formula.
My front brakes calipers were already seized and prematurely hard at 10kMi after slides went dry. I did not want the dealer to screw with my brakes so I popped my weels to lube them up right.
ceramic fortified HTemp Silicone brake lube
This is the pure silicone formula I use everywhere around this vehicle, regardless it cost $15/tube. Permatex has some competitive products as well.
false claims junk synthetic brake grease
I used to use "synthetic HighTemp petroleum brake grease": pure junk that turns into gum... great for pad back sides to act as glue, not so on slides at all.

thanks for the reco. I ordered the above. Hope it isn’t fake claims like you experienced.
this is good stuff 👍
Cherry on your cake if you have a "helper" available ...
reassemble everything
make the pins loose or 2 fingers tight
ask the helper to apply brakes gently
tighten pins to final torque under brake tension
This steps precisely super-aligns the caliper pins to the caliper for powerful smooth brakes that last at the way near pad backing - Redo this at half-life when you relube pins.
Without doing the pins self-alignment, brakes work not too bad "within specs". Hard+soft instead of velvet+strong.
My mechanic does front brake rotors/pads in around 30-45min, two trolley jacks.
Anyway, just wanted to make this post for brake part numbers for AMG (Sports) pack cars, in Australia :
