The cars made after 1926 are known under the name of Chaigneau-Brasier, after the company was bought by the Chaigneau family who had been bicycle makers. The first car made by the new company was the TD-4, a 9 CV 4-cylinder model available as a tourer or saloon. The company appears to have sought a return to its "luxury car" strategy of ten years earlier, now combined with elements of technical innovation for which its traditional customers had not been prepared, introducing a 3-litre OHC-engined front-wheel drive car, described by one commentator as "Utopian", in 1928 An even larger model followed in 1930. In view of the severe economic downturn crystallised by the Wall Street Crash of October 1929, the timing of this venture was unfortunate. The new large Chaigneau-Brasiers attracted plenty of interest at the annual Paris Motor Shows. A journalist described the 3-litre car of 1928 as sitting on "le châssis le plus moderne du salon [1928]" "("the most modern chassis at the 1928 Paris motor show")" but it turned out that the car displayed was only a prototype, and it is not clear if any were actually produced for sale. The company fell into acute financial difficulties. With production capacity at the Ivry plant now badly under used, nemesis was postponed by a major investment from Delahaye who were at this time still short of capacity themselves, and were able to transfer some truck production to the Chaigneau-Brasier plant. Chaigneau-Brasier were therefore able to survive, but only till 1930 or 1931. Sources differ.
