I took an ML63 20x10 wheel off my black car last night andtried to fit the PB 405mm template. Slightly to my surprise it didn’t fit. There was a slight foul on the outer edge/corner. Not sure if that’s a real corner, or just the corner of the envelope. Anyway, it onlyapplies to the large PB 8 pot calipers. I’m considering using my Brembo calipers, which have about 25mm clearance as they stand, which I think is sufficient.
405x36 seems to be size to go for, so the only remaining decision is whether to go for fixed or floating rotors. I’m not clear what the advantages of floating are. Some say they have better cooling,but it looks to me like it would be worse. There’s a mechanical discontinuity between the rotor and the bell, so floating rotors won’t conduct heat to the bells very well, losing some dissipation capacity. The advantage seems to be that the rotors can get hot without suffering from the mechanical effects of the temperature differential with the bell. In order words the rotorcan expand without constraint and without warping. It sounds like a good idea, but there seems to be a consensus that floating brakes are best reserved for the racetrack. In many ways it’s quite reassuring that PB brakes are used for racing, which is generally beyond stock/ road brakes. They must be quite good. Of course it might even be possible to achieve floating rotors by putting springs under the bell attachment nuts, and locking the nut. It’s not something that want toworry about though. Nick |

I have 330mm rotors on front and rear on CL 600 from Japan and I need replace front rotors, can I buy 345mm rotors? Will these fit the calipers with codes 20.7045.03 and 20.7045.04?
And second question: Do you think I could put 360mm rotors into my original 18 "wheels. There is more than 2cm of free space beside the caliper and wheel. Would it be enough to buy larger rotors and 8 piston calipers or would I need to upgrade something else too? Thanks. |
I have these 8 pistons calipers, to me the best
Brembo 8 Piston AMG calipers Mercedes W220 W215 S55 S65 S63 CL65 CL55 CL63 https://cimg4.ibsrv.net/gimg/www.mbw...47d11d82e8.jpg https://cimg1.ibsrv.net/gimg/www.mbw...c19a745610.jpg https://cimg2.ibsrv.net/gimg/www.mbw...d557689847.jpg |
I have answer to my first question. My mate have ML 55, he has same calipers and 345mm rotors with 17" wheels, so I am buying 345mm.
|
I did end up getting a full set from an S55, I actually bought an S55, swapped the brakes between my car and that car, and then sold the S55, so the only cost to me was the new pads/rotors I purchased for the 55 brakes, as they were worn out. The holes for the bolts that retain the caliper were smaller on my 600 knuckles, so I drilled them to fit. The 600 calipers fit the 55 knuckles fine, did have to trim my backing plates for the larger caliper and rotor too. Great upgrade for the money, plus they fill out the AMG package 18" wheels on the CL nicely.

The brakes are very confusing, seems US model have different sizes as EUR models and they kept switching

I think the 215 to 216 front caliper upgrade is the most cost effective way to get big brakes on the 215/220 chassis. $150 per caliper, $140 per 390mm rotorhttps://cimg6.ibsrv.net/gimg/www.mbw...9151b4c744.png
W216/221 rotor that’s needed https://cimg7.ibsrv.net/gimg/www.mbw...9d0bbc532.jpeg Mounting ears need drilled out slightly to accommodate the larger caliper bolts from the 216/221 brakes https://cimg8.ibsrv.net/gimg/www.mbw...543c32db0.jpeg Yellow to match the valve covers https://cimg9.ibsrv.net/gimg/www.mbw...2e8221608.jpeg Valve covers to match the calipers https://cimg0.ibsrv.net/gimg/www.mbw...5861855f2.jpeg Caliper figment against 20” wheel. Maybe certain 19” wheels would fit but I’m not sure. I also had to trim my dust shield very slightly for proper fitment |
From where you have these prices? I believe that you just forgot zeros in amounts.

Mounting ears need drilled out slightly to accommodate the larger caliper bolts from the 216/221 brakes You used rotors from 216? Pług and Play? For 215 CL65 rotors had 390 mm but not the same? |
You drill out the mounting holes but otherwise yes it’s plug and Play
w215/216 cl65 brakes are different |
Screw dif

w215/216 cl65 brakes are different In my country sometimes I have really winter. For winter I use 18' wheels and need to replace brakes between seasons. If I change mounting I need to by brakes 360 mm from 216 to. I have company use CNC which prepare mounting and rotors plate for front brakes system from Porsche. Price is approx. 4k$. Its lower than Brembo bbkit. But not professional. In the same price is complete new front brakes system from w215 CL65 - oryginal calipers, Brembo rotors and some good pads. Old AMG calipers had a problem with good pads ex. Mintex, Carbone Lorraine had only race pads for it. Road use pads (R90) is not for this car weight, speed and acceleration. |
