Honda has officially announced a recall of 471,820 cars and minivans because of a faulty seal in the brake master cylinder. The recall affects 2005-07 Honda Odyssey and Acura RL models.In the recalled vehicles, the seal may fail and allow brake fluid to leak and then cause loss of brake response. This could lead to soft brake-pedal feel and the possible loss of hydraulic braking circuits, the company says.This recall is directly related to the Toyota recall earlier this week of 728,544 models in the U.S. The two companies share the same supplier for this part.Honda advises owners who see any illuminated warning lights to bring in their vehicles for service immediately. The brake fluid light will always illuminate if the vehicle experiences this defect, the company says.Recall notices will be mailed out in the next two months with instructions for owners. Honda owners can call 800-999-1009; Acura owners can call 800-382-2238. Owners can also call the National Highway Traffic Safety Administrations hot line at 888-327-4236.
