If I read the specs for U. S. options correctly, the P71 brakes in the Dynamic Plus pkg are the larger 16.8" front rotors (vs 15.75" in U29) and are also painted red.

At the risk of beating this horse to death, does anybody know if the brakes that come with the Dynamic Plus package are the same exact pieces found on the GLE63S?
I assume (hopefully correctly) that these are the brakes I have coming with the Dynamic Plus package?
No, they're not. The brakes shown are for "High Performance Brakes," with only two pistons front and one piston rear. They may be for another market.
Both the "AMG High-performance Braking System w/silver calipers" AND the "AMG High-performance Braking System w/red calipers" (U70, part of the DE6 AMG DYNAMIC PLUS Package) have six piston calipers, according to the M-B configurator.
The Silver calipers show 15.75" front rotors, and the Red calipers show 16.5". I don't think the calipers are the same internally.
In any case, the Dynamic Plus brakes are a lot more powerful than the Silver Caliper kit.

I suspect they are.
There are other things in the 53 that are changed from the 450 / 350, including front suspension / steering bits that increase the turning radius by more than a foot, with the Dynamic Plus Package. I'll bet it's knuckles and maybe even geometry.
I doubt that M-B would make an entire new package for a low volume car such as the 53, so my bet is on "yes, they're the same." Plus steering and other associated things.

I do not think there are any differences in rotors and hardware between Red and Silver calipers (other than the color of course).
Take a look:
That is how it was for W166 GLE 63/63S (Silver/Red) and X166 GLS63 (red no cost option).
It still IS for new X167 GLS63 (red is still a no cost option, so if there were any hardware differences, it would be reflected in price).
Getting these brakes for 53 is a no brainer, at least for me. Wether it is silver or red (color only, NOT hardware) depends on if one wants/needs ARC.
Which ever one is chosen it is miles ahead of standard 53:

They look identical in the Configurator, probably because it looks like they just Photoshopped the silver photo to red.
But the description says Red disks are 16.5" compared to the Silver 15.75". I have never accurately measured my red discs.
It's hard to tell the difference on a test drive, because you won't feel it until the brakes are bedded in. Not something you could do on a test drive.
If it's performance you're looking for, get the Active Ride Control. It makes the car a star, and it's well worth a couple thousand extra, compared to just the silver brakes.
I can add that the red calipers found as part of the Dynamic Plus Package have the same option code (U70) as the brake code for the GLE63. (I asked this above, mikapen largely confirmed, and I found concrete evidence this week) I can't help with the comparo of the silver calipers versus the U70 pieces...
I guess the best way to know if they are in fact identical is to find out the p/n of GLE63 front (standard equipment Red) rotor and the p/n of GLE53 front rotor when equipped with Silver $2,500 U29 brakes option. If they are the same - then everything is the same, excepts calipers' color. P/ns of the calipers is of no use since they are different due to color scheme. Currently it is difficult on-line since MB on-line dealers do to show 63/53 brakes at all.
There is no longer need to argue, guess, whatever.
This is Ron's thread, he's one of the first (if not the first) with GLE53 with ARC (with red calipers). Rotors are (as I was sure) are 15.8", or the same as "Silver" $2,500 option. (I believe that 63's has to be the same as 53's ARC at 15.8" and not 16.5" quoted on mbusa).

Now that it was definitively established (thank you Ron) that 63/53DPP(red)/53U29(slv) all use identical 15.8" 2-piece rotors (not 16.5" stated on mbusa) and hence internally identical calipers, I am curious if standard 53s have 15.8" 1-piece rotors as stated on mbusa or if they are 14.8" and identical to '20 580 14.8" rotors.
This is 63/53DPP on actual 63 car:
This is 53 standard on actual car:
This is '20 580 car:
If one takes a closer look, standard 53 and '20 580 rotors seems to be of the identical size. We know that '20 580's rotors are 14.8" (same size as W166 ML550 and GLE43).
Furthermore and more importantly, the calipers look to be identical in size and hardware placement on the rotor with only difference being decorative cover plate ("AMG" on 53 and "Mercedes Benz" on 580).
Brr168, if you still have your original 53 rotors available, do you mind taking the measurements, please? Looking at the closeup of this image: https://cimg6.ibsrv.net/gimg/www.mbw...d194a82767.jpg
fronts are significantly larger than rears.

Just a brake sensor harness and new brake lines to accommodate the larger system. Pretty straight forward installation.
Hi Brr168,
Just recently upgraded to red AMG 6pistons brakes.
However felt that the brake is too soft as I really have to step further to the floor to brake.
Especially when its low speed or on traffic.
Ive did the bleeding of the brakes maybe 6-8times already.
Question is do the brake lines needed to be changed? Because I think that's the only thing that I haven't replaced.
Thank you and please any information is greatly appreciated.

Hi,
sorry, I didn’t have any braking issues after the install. I do remember my installer said they had to change to the larger brake line, not sure if that was the issue.
