No brakes: Brake pedal went all the way to the floor without vehicle stopping. Upon my personal inspection at time of incident, I found the brake fluid reservoir to be full and no brake fluid leaks, anywhere, were found. The Toyota service manager where I bought the vehicle stated that cause was a defective master brake cylinder assembly. I believe this is a manufacturing quality issue as I have not heard of a master brake cylinder assembly malfunctioning within a two year time frame.

Purchased pre-owned 4 runner "certified? from russel Toyota 12/07 with approx 21K miles. Complained of unusual brake performance immediately but was told the vehicle was ?performing to factory specs? brake performance issues including aggressive stopping, stiff pedal, loss of pressure, and random ?anti-skid system? responses nearly caused a few accidents. On 3/14, approx 23K miles, complete brake failure, no pressure, accident avoided and coasted vehicle to a stop, pressure did not return. 4runner towed to dealer, master cylinder was ?internally leaking" and replaced. Symptoms continue and vehicle is completely unsafe. Numerous attempts have failed to re-produce the intermittent problem at the dealer and therefore the dealer keeps saying there is nothing wrong. Vehicle is unsafe and Toyota unwilling to help and referred us to ncds dispute resolution program or told us we can file a suit. This vehicle is unsafe and should be replaced. Breaks continue to fail/malfunction approximately 1 time per week. Dealer always says no problems found.
