Does anyone know where to find a brake parts diagram for our AMGs' brakes, specifically front? Every diagram that comes up on MB websites is for the base C-Class. I've never encountered something this (repeatedly) inaccurate before and it's quite frustrating.

Trying to figure something out with the bleed screws, specifically on the front calipers.

This pdf shows the calipers pretty closely, you didnt mention what you are trying to figure out but I believe these are the bleeder screws

Provide a VIN and I'll post what you need.

Thank you both.

I'm trying to determine if I have some brake fluid seepage past the bleed screws. I've had the calipers apart before (installed high temp piston boots last Fall) but cannot remember if there were any sort of rubber seals associated with the bleed screws (maybe internal to the caliper). The paint on the calipers has been going to hell (though that started before I purchased car) and at track events and/or maybe all the time (hard to tell) the areas around the front (outer at least) bleed screws appears "moist".

VIN is WDDGF7HB6CA682592

Here you go. Hopefully you'll find what you're looking for.

Thanks!

But no...I won't. That's a parts diagram for a base C Class with a single piston floating caliper

Valvestud

It's the front brake assembly from the VIN you provided, directly from MBUSA. So not sure what you're seeing.

i think you're too focused on the photo itself. looks to be a generic image but those part numbers look correct for a C63

I'm aware that the bleed screw is the correct part number (in fact it appears to be used on over 270 Mercedes models). Wasn't sure if there was some seal as well. And if the diagram isn't right then I don't know what I'm looking for. I'm coming to the conclusion there isn't; but wanted to leave no stone unturned.

Thanks for your time

Ya the picture is garbage on EPC and always has been and shows a base c300 caliper, all the part numbers and parts are correct for the C63 in EPC but I agree it is not super helpful when they use a picture of something completely wrong.

Dr.Speedfellow

There is no separate seal. You can try replacing the bleeder screw, but if that doesn't fix the fluid leak at the bleeder orifice then it is likely the caliper orifice itself. A lot of people over tighten bleeder screws thinking 'tighter is safer' but as you can see in this basic description of how one works, tightening too much probably just damages things. First thing I would do is try to remove the bleeder screw if it is very hard to get out, it was probably over torqued.
