Tokyo ? Toyota is recalling about 400,000 of its signature Prius green cars and other hybrid vehicles worldwide for braking problems, the latest in a string of embarrassing safety lapses at the world’s largest automaker.

Toyota Motor Corp. president Akio Toyoda will hold a news conference at the automaker’s Tokyo office today to outline details of the braking problem, a company official told The Associated Press.

The braking problem for the third-generation remodeled Prius is the latest safety woe for Toyota, which is already trying to fix problems in millions of vehicles recalled for other defects, including a sticky gas pedal.

There have been nearly 200 complaints in Japan and the U.S. of drivers experiencing a short delay before the brakes kick in. The delay doesn’t indicate a brake failure. A fix requires new software that oversees the controls of the antilock brakes.
