It happend so that I got brand new brake system set from MB E 212 AMG at my wearhouse.
\nHolding carbon rotor for the first time in your hands you feel you\u2019ve been cheated all your life. Size and weight just don\u2019t seem appropriate for each other! And the thought sinks in \u2013 cast-iron is only good for barbell plates!<\/div>\n<\/div>\n
<\/div>\n
\"rotors<\/div>\n
That\u2019s how I came up with an idea to create a comparison review of three differet rotors of the same size.
\n1. MB E212 AMG brake rotor 402 mm, 39 mm thick, 7,65 kg of weight.<\/div>\n
\"brake<\/div>\n
\"directed<\/div>\n
Directed ventilation , aluminium alloy hat,\u00a0 thermal expansion compensation of mobile bobbins.<\/div>\n
\"carbon<\/div>\n
Upper calculated temperature limit for carbon-ceramic brake rotor is unbelievable 600 degrees Celcius, or 1112F.<\/div>\n
Though, I must say, that this kind of temperature carbon-ceramic rotor could not stand for long.
\nCarbon gets oxidized and the rotor structure rapidly loses it\u2019s hardness.
\nThe oxidation level of a rotor can be determined, believe it or not, by it\u2019s weight.<\/div>\n
For each rotor there is an information displayed on it\u2019s hat.
\n\"minimumParticularly in this case it\u2019s min. weight is 7569 g., scales show 7655 g., that means this rotor is new and have a long road ahead of him \ud83d\ude42<\/div>\n
Brake rotor working surface coated with practically the hardest material (not counting girls\u2019 best friends) \u2013 silicon carbide\u00a0SiC (melt.t.\u00a0 2830\u00b0\u0421) chemically stable, by hardness it\u2019s second only to diamond and boron nitride.
\nManufacturer claims that it does not wear off, which is quite easy to believe.<\/div>\n
Steep price of carbon-ceramic rotors determined by the production complexity and high labour input, as the carbon-ceramic rotor production process\u00a0takes several weeks to complete.<\/div>\n
\n

One of the production steps is curing in an oven under the 1300 C temperature for 24 hours.<\/p>\n

2. Brake rotor BMW M5 F10 400 mm diameter, 36 mm thick, weight 13,9 kg.<\/p>\n<\/div>\n

\"Brake<\/div>\n
<\/div>\n
\"Brake<\/div>\n
This brake rotor working surface made out of cast-iron, to increase the internal channels surface and the air flow through those channels, the ventilation is intentionally directional.
\nThere are left and right brake rotors.
\nUpper calculated temperature limit for it is 450 C.<\/div>\n
For this kind of temperature provisions for\u00a0 thermal expansion compensation of the brake rotor\u2019s working part must be made.
\nAs rotors are produced on a large scale, the elegant and reliable design was chosen.
\nSteel locating pins get inserted right after the channels are drilled into the working part of the rotor.\"locatingOne end of the pin has a nail head like thickening.
\nThose heads are perfused in liquid aliminium alloy under pressure.<\/div>\n
\n

This structure turns out light and cost effective.<\/p>\n

3.BMW X5M brake rotor, 395 mm diameter, 36 mm thick. Weight \u2013 17,53 kg.<\/p>\n<\/div>\n

\"BMW<\/div>\n
\"Three<\/div>\n
\n
This giant is a heavy weight\u00a0 champion.<\/div>\n
When I saw it for the first time ( and lifted it with my own hands), I thought it was the train\u2019s brake rotor, it was that heavy!!
\nEven though this rotor has an aluminium hat and directed ventilation.
\nTwo parts of it are joined by studs.<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
