The problem
Honda is recalling certain model year 2005-2007 odyssey and Acura rl vehicles. Brake fluid containing polymers is used that acts as a lubricant for certain brake system components. If replacement brake fluid is used that does not contain such polymers, or that contains only small amounts, a part of the rubber seal located at the rear of the brake master cylinder May become dry, and the seal May curl during movement of the piston. If this occurs, a small amount of brake fluid could slowly leak from the seal into the brake booster.
The risk
A leak of brake fluid could lead to a change in brake pedal feel and overtime a degradation in braking performance increasing the risk of a crash.
The fix
Dealers will replace the brake master cylinder seal free of charge. The recall is expected to begin during December 2010. Owners May contact Honda at 1-800-999-1009.
