What Happened
The brake master cylinder is a crucial part that helps control your brakes. In certain 2004-2006 Toyota and Lexus models, a specific type of brake fluid can cause the rubber seal at the back of the master cylinder to dry out and potentially curl.
Risk if Unfixed
If this happens, a small amount of brake fluid could leak into the brake booster, changing the feel of your brake pedal and eventually affecting your braking performance. This could make it harder to stop your vehicle, increasing the risk of a crash.
Free Fix
Your dealer will replace the faulty seal with a new one, free of charge. Schedule the repair as soon as you receive the recall notice.

Original — What Happened
TOYOTA IS RECALLING CERTAIN MODEL YEAR 2005-2006 AVALON, MODEL YEAR 2004-2006 HIGHLANDER, MODEL YEAR 2004-2006 LEXUS RX, AND MODEL YEAR 2006 LEXUS GS AND IS VEHICLES. BRAKE FLUID CONTAINING POLYMERS IS USED THAT ACTS AS LUBRICANTS 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.
Original — Risk if Unfixed
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.
