6 pot AMG caliper mounting brackets

[500AMM]

Thanks for the answer!
May be you will post some pics of your brakes set with exact part numbers?
We have plenty of calipers here in Russia avaialable.
Even gt-r r35 calipers are not so expensive.

OK, I'll post the PN's later on.

Another comment about the E-class brakes, which applies for any larger/heavier MB like S, SL, CLS... The rotor has an higher hat and the disc is 36mm, so they won't clear the LCA ball joint. 36mm discs is not needed for the 036 either due to its lower weight. Another drawback is the extra weight on 36mm vs. 32mm, plus you need a larger caliper. All in all it adds up 30% weight increase per side!! compared to the 6-pot 360x32mm for the CLK/SLK cars.

Interesting about the caliper availability in Russia, I could need some advice to find something there. But the GT-R has 380x35 rotors both front & rear, so their rear 4-pot calipers won't fit so good on 340x32 rotors. The enclosed images shows of a couple of newer 4-pots I would look for.

And which setup fit better and requires less work - 340x32 or 360x32 on front? In both variant we will need custom bracket and this is not a big problem.

The grey calipers on previous post - arent they from gla45 front? I know zero rear amg calipers with such type of mounting. If there are something it will make work much easier

The 6-pot 340x32 does mechanically bolt up more or less directly, but it is far from a plug & play! I guess the simplified install I have seen will work, but it is totally outside my comfort zone:

- the stop buffer on the steering knuckle is cut off with a grinder.
- a tiny bolt is tapped into the lower end of the caliper mounting bracket to work as a stop buffer.
- the mounting bracket was shimed out a bit with some washers.
- the origin brake line port was plugged.
- the brake line was connected to the inner bleeding port on top of the caliper.
- a tin shears is used to cut the brake shield in place, to clear the caliper.

A custom mounting bracket will solve the stop buffer issue. The origin brake line port is a sticking out and conflict with the steering arm and need some remachining to clear. A deeper tapping in the port, and a banjo fitting is needed to attach the brake line. The stock brake shield should be replaced with a bigger, modified shield from another car. The 6-pot 360x32 setup has more clearance to the steering arm & knuckle, but requires the same procedure though.

I haven't come close to any technical details about the newer 4-pot caliper with separate mounting bracket yet. The grey calipers may well be for the GLA45 front, while the red ones are a bit different and I think they are for rear brakes, but not sure.

The silver 4-pot on the enclosed images is the 2nd version AMGs I have. I think it could be possible too mill off the integrated mounting bracket, and machine mounting holes and proper bolt seats on them. It even looks like they were meant for that with the two round recess on top of them. But I'm not sure the bolt hole will clear the fluid channel inside, so it's not as simple as it sounds to be. I don't like to do such machining on them either due unknown strength and weakness issues.

Hah, you really hit the nail!

That is exactly the machining I was talking about. That proves it can be done, but I'm still concerned about any potential weakness of the caliper. Should be great to see some detail photos of the machined areas.

I am not sure what you guys are talking about at this point. I already made a bracket that makes the clk/slk 6 pot amg brake a bolt on deal. I set it up for the 345mm rotors from a c55 but if you wanted them for the 2 piece 360s that would be super easy. Or you could just get 2 piece rotors for the c55 in the aftermarket. Or and I would have to check the 340mm rotors. I do not know if I could get them to work with those. The only modification is the backing plate has to be cut. That is is. They work with either the one piece or two piece control arms.
The rear calipers are bolt on.

Re: 6 pot AMG caliper

Here they are.

good day dear members! Where can I buy these custom bracketets?
