Toyota has announced yet more recalls.
Yesterday, Toyota Motor Sales U.S.A. announced a voluntary safety recall of certain Avalon, Highlander and Lexus models for the possibility that brake fluid could leak from the master cylinder and trigger the brake warning light.
The models in question are the following:
.....2005 through 2006 Avalon.
.....2004 thrugh 2006 Highlander(non Hybrid) and Lexus RX330
.....2006 Lexus GS300, IS250 and IS350.
Here's the explanation from the Toyota press release:
The Toyota genuine brake fluid used during vehicle assembly for vehicles sold in the United States contains polymers. The polymers act as lubricants for certain 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 occurs, a small amount of the brake fluid could slowly leak from the brake master cylinder into the brake booster, resulting in illumination of the brake warning lamp.
If the brake warning lamp has illuminated and 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.
The release says owners of affected vehicles will be contacted beginning in early November by first class mail and that Toyota and Lexus dealers will replace the brake master cylinder cup with a newly designed one at no charge.
