True. I just didnt realize they used Bosch parts in the early 90s on GM cars.

Not sure about them "not knowing" since American cars had ABS brakes before German cars. I knew this and Wikipedia will verify that in 1971, Chrysler Corporation together with the "Bendix Corporation", introduced a true computerized three-channel all-wheel antilock brake system called "Sure Brake" on the 1971 Imperial. It was available for several years thereafter, functioned as intended, and proved reliable. General Motors introduced the "Trackmaster" rear-wheel (only) ABS as an option on Cadillacs starting in 1971 and Ford Motor Company started offering it in 1970 as an option on Lincolns and named their system Sure-track. It was also rear wheel only.


Maybe Chevrolet used the Bosch system since it was better and since the Caprice was new for 1991, they wanted the best system out there? I dont know.
