Toyota Avalon Brake Master Cylinder May Need Replacing at 125,000 Miles

(5 reports)

At 125,000-150,000 miles, the Brake Master Cylinder may need replacing. When replacing the master cylinder, it is critical to adjust the brake pedal to master cylinder pushrod clearance or the brakes can drag and overheat.

Brakes failed to work without extreme force on pedal, crunching felt pushing pedal, brakes locked up & unable to move car!! Towed to shop, master cylinder stuck, autopsy confirmed internal part in m/ cyl broke and seized up piston return. Really glad it happened pulling into our garage. Could have been a tragic situation, perhaps NHTSA should be advised.... Has happened more than once.... Seems to be XLS models with VSC ... Same?? -
Brakes were intermittently soft for a couple of weeks and we had it looked at. The master cylinder needed replacing along with rotors and pads. It was kind of scary as it would occur when you weren't expecting it, and if you pumped the brakes then they would get high and work. -
