Master Sistemas Automotivos Ltda., the largest manufacturer of air brakes for commercial and towed vehicles in Brazil, headquartered in Caxias do Sul / RS, was established on April 24, 1986, as a joint venture between two leading companies from the road equipment and automotive sectors: Randon S.A.- Implementos e Participações, of Caxias do Sul, and ArvinMeritor Inc., located in Troy, Michigan, United States. To meet the challenges posed by roads, Master develops sets of brakes for commercial vehicles with the latest technology.


It is the leading manufacturer of air brakes nationwide, offering the best solutions for trucks, buses, minibuses and road equipment, accounting for 54% of the domestic market. It also exports brake components and brake assemblies, in addition to serving the Aftermarket.

Master has achieved certifications in the quality system of the automotive sector: ISO/TS-16949, ISO 14001 and OHSAS 18001. It stood out as the first company in the country`s southern region to receive the QS9000 certification in 1997, and the first in the northeastern region of Rio Grande do Sul to receive the RS Quality Award – PGQP Gold Award. In 2004 and 2005, the company received the award for The Best Company of the Automotive Sector, awarded by Exame Magazine. At the end of 2005, Master was among the 150 Best Companies to Work For in Brazil for the second time. In 2010, Master reached the mark of 6 million brakes produced since its establishment.

In fiscal 2010, Master`s net income was R$ 431 million, a growth rate of 58% over the previous year. Exports totaled US$ 18.5 million, 78% up from 2009.


In 2003, Master signed a partnership with the German company Eisenmann, creating Mastertech, which offers surface pre-treatment and painting through the e-coat cathodic electrodeposition process. It also provides surface finish with epoxy-polyester paint (top-coat), meeting the requirements of the national and international markets.

Designed within advanced production techniques, combining high- technology surface treatment to modern concepts of integrated logistics, Mastertech shows true zeal for the environment through a painting process that is free from heavy metals thanks to low levels of organic solvents used in its composition. Its powder painting process is environmentally-friendly, as it is totally solvent-free. Mastertech is operated by Endosul – an Eisenmann company – the German company that is the owner of the technology for the painting process and the latest equipment.
