Selling AMG Calipers that I never ended up putting on my E350 4matic. Will ship buyer pays for shipping. Test fitted them and that was about it I have SS brakelines as well. PM if interested will be going through PayPal

 

Reason for selling just in case you want to know, the car was totaled by a f*cktard that ran a light.

 

How much?

 

Do all w212 cars have the same master cylinder size and bias?

 

What car did they come off?

 

1600 they came off a E63 and I have no idea about the master cylinder.

 

What year e63, but for $1600 you can get them brand new from the dealer.

 

edit, I thought you're only selling front brakes didn't see the title says rear too.

 

Yes front rear and stainless steel lines.

 

I wonder if the booster and master cylinder support the large calipers, or if the AMG uses different versions. Anyone know?

What year E63 are these off of? Part numbers?

 

One big reason I avoided the E63 is because I started looking at running costs, and the brake rotors on the front cost over $1000 each, not to mention pads, and you can only get them from MB, there are no aftermarket.

 

I think your referring to the E63 special option ceramic rotors. The iron rotors on the front of the E63 4matic are the same iron rotors as the E550 4matic.

 

The part numbers are not the same front or rear. The rear are not terrible, but the front - I see that my usual parts site has the fronts now discounted to $865 each, but definitely not the same part as the E550. These are the standard rotors, I'd hate to look at what the upgraded brakes cost.

OEM front rotors on the same year (2010 as example) E550 sedan cost $137 on the same site.

 

You are correct while not exactly the same as the stock E63 irons are 2 piece and stock E550 4matic are 1 piece but they are technically interchangeable based on specifications other than weight. The E63 rotors are ~7 pounds lighter.

There are also aftermarket options for even lighter weight 2 piece rotors than the stock E63 that fit both cars.

There are also 1 piece aftermarket options in addition to the stock E550 rotors if you wanted to go cheap on a E63 or amg front rotors setup or just want a replace E550 without going lighter.

 

since you seem pretty knowledgable, what is the difference between the E550 calipers and the E63 calipers if the rotor is the same? Also, I notice that my 2012 E550 calipers look different and much better than 2010-2011 calipers. They look more like what you have pictured here.

 

E63 amg labeled calipers are fixed 6 piston while the m278/550 4matic labeled mercedes benz calipers are fixed 4 piston. Both use same size and offset rotor from everything I can find.

Also the E63 labeled amg rear calipers are fixed 4 piston running a much larger rotor (same size as front but different offset and thickness)than the m278 cars which have the sliding no label single piston rear calipers.

I am new to my E550 so still learning, there isn't very much information out there. I have a question out to racingbrake about front brake pad capability as they state they offer aftermarket pads for the m278 front caliper in a few compounds during testing with the cls550 but their pad size doesn't sound right; as in general there is are no options that I could find other than the stock mb pads that fit the m278 which in all fairness seem to work just fine.

 

I see a few pad options for m278 sedan AWD fronts on Rockauto.com or other sites. (searched using 2013 model)

 

Since the brake system is electronically controlled, and the questions regarding master cylinder, etc. I would be very hesitant to just go swapping calipers. Personally, I don't intend to track my car anyway, so no sense in spending thousands to upgrade a system that seems to be working just fine for my needs as it is. It's a fast mid-size sedan, not a race car.

 

I have new pads that come with the calipers.
