The company said today the recall applies to about 233,000 Prius vehicles made between March and October 2009 and about 9,000 Lexus HS250h models made between June and October 2009.
Toyota said the Prius vehicles affected are sold worldwide. The Lexus sedans are sold in the US and Japan.
The automaker said brake pressure parts in the vehicles could crack due to vibration, slowing response times. It said there were no accidents or injuries caused by the problem so far.
Toyota suffered a blow to its reputation from a series of massive recalls in 2009 and 2010, including faulty braking, sticky gas pedals and defective floor mats.
