I'm big into mountain biking and recently read about some graphene brake pads that supposedly have better performance.

Real graphene is too expensive for something like brake pads and so the article says the pad compound uses a “specially modified graphene”.
After doing further research, both the Chinese and the Australians make something similar to graphene using plant materials.
Chinese article:
My Honda HR-V needed some new pads. OEM served me well but I was curious if there's something out there that can give better performance than OE but with no dust.
These two brands came up when searching the forum:
Carbotech 1521:
Peak Friction Coefficient: ~0.45.
426C
Dixel M:
Friction Coefficient: 0.39min, 0.4average, 0.52max.
500C
Chinese Graphene Pads:
Friction Coefficient: 0.45-5.
650C
Carbotech originally said they could make 1521 pads for the HR-V but then ghosted me after realizing the work was worth more than the efforts.
The Canadian distributor for Dixel also ghosted me after asking if the Dixel M's can be special ordered from Japan.
Since the Chinese tech is patented and supposedly has ECE R90 E-Mark from Europe, I decided to give them a try.
I've only driven on them for a few hundred miles but so far, the pedals do feel like I have to press less so the friction coefficient does seem to be accurate.
Had a lot of doubts but I think I'm going to be very happy with these.
Total cost paid: $100USD for both front and back pads + shipping to Canada

Australian article: https://www.technology.org/2019/06/...-make-graphene-200-times-cheaper-and-greener/From August 25th to 26th, the 2016 China Science and Technology Innovation Talent Investment and Financing Training Camp hosted by the Talent Center of the Ministry of Science and Technology and the Jiangsu Provincial Department of Science and Technology was held in Jiangning High-tech Park. After layers of selection, 9 entrepreneurial teams stood out from a large number of competitors across the country, and held a road show on the 26th to connect with financing institutions. Among them, the new technology of Jiangsu Jinmaisui New Energy Technology Co., Ltd. using "straw to make graphene brake pads" has opened people's minds.
The burning of straw by farmers has brought great pollution to the atmosphere. Is there a better way to deal with it? Xiong Wanjun, Chief Engineer of Jiangsu Jinmaisui New Energy Technology Co., Ltd. said: Yes! In his eyes, straw is a treasure, which can be made into artificial graphene, and then made into graphene brake pads.
The reporter learned that graphene is a two-dimensional crystal composed of carbon atoms with only one layer of atomic thickness. In 2004, physicists Andre Geim and Konstantin Novoselov of the University of Manchester successfully separated graphene from graphite. The material is not only thin but also strong, with a breaking strength 200 times stronger than the best steel.
The researchers of Jiangsu Jinmaisui New Energy Technology Co., Ltd. discovered that graphene does not have to be obtained from graphite mines, and graphene can also be extracted from waste straw. The reporter saw from the vcr video brought by Xiong Wanjun that the workers first crushed the straw and put it into a carbonization furnace for smokeless incineration. After carbonization, graphitization, redox and other steps, artificial graphene was produced. The artificial graphene is then processed through mixing, pressing, sintering, heat treatment, strengthening treatment, machining and other processes to finally complete the production of automobile brake pads. "Look, this is a video of our braking experiment. Two BMWs of the same model, one uses traditional ceramic brake pads and the other uses graphene brake pads. The latter brake distance is obviously shorter and the noise is lower." Xiong Wanjun said .
The experimental data further shows that the high temperature resistance of graphene brake pads is 13 times that of traditional brake pads, the impact strength is 4 times that of traditional brake pads, the wear resistance is 6 times that of traditional brake pads, and the acid and alkali resistance is 13 times that of traditional brake pads. 15 times.
Compared with natural graphene, graphene brake pads made of straw have low cost, less environmental pollution, and abundant raw materials. The annual return is expected to be 30%. At present, Jiangsu Jinmaisui New Energy Technology Co., Ltd. has signed acquisition agreements with more than 20 major rice straw producers in the province, which not only protects the environment, but also increases farmers' income. At present, the company's straw graphene brake pads have been identified as "international initiative, domestic advanced product" by the Jiangsu Provincial Economic and Information Commission, and have passed the provincial new product appraisal, and the product has also obtained the European market exemption certificate.
