Toyota will voluntarily recall more than 1.66 million of its vehicles worldwide to inspect them for possible faults in the brake master-cylinder seals, it was announced today.
Toyota Motor Sales (TMS) USA, Inc.,Â will conduct a voluntary safety recall of around 740,000 vehicles sold in the United States. These include â€“ 2005 through 2006 Avalon, 2004 through 2006 Highlander (Non Hybrid) and Lexus RX330, and 2006 Lexus GS300, IS250, and IS350.
The recall is because there is a possibility that a small amount of brake fluid could slowly leak from the brake master cylinder in affected vehicles.
This action follows an announcement made a few hours earlier by Toyota Motor Corporation in Japan, who are recalling 600,000 vehicles in Japan.
The Toyota genuine brake fluid used during vehicle assembly for vehicles sold in the US contains polymers, which act as lubricants for some brake system components. If during vehicle maintenance, brake fluid is used that does not contain such polymers — or only small amounts — a part of the internal rubber seal (brake master cylinder cup) located at the end of the brake master cylinder piston may become dry and may curl during movement of the piston.
If this happens, a small amount of the brake fluid could leak from the brake master cylinder into the brake booster, resulting in illumination of the brake warning lamp. Then, if the vehicle continues to be operated without refilling the master cylinder brake fluid reservoir, the driver will begin to notice a spongy or soft brake pedal feel, and braking performance may gradually decline.
Owners of the involved vehicles will be notified by first class mail beginning in early November 2010. Toyota and Lexus dealers will replace the brake master cylinder cup with a newly designed one at no charge to the vehicle owners.
