In owners' own words
Brake problems; when approaching a stop sign, the Suburban did stop. Then all of a sudden, it seemed as though the brakes released with driver's foot on brake pedal, and the Suburban proceeded though intersection. Would not stop even though driver's foot was on the brake pedal. When driver reapplied brakes the Suburban finally came to a stop. No traffic was coming in the opposite direction at the time.

Ea95026, poor brake performance; on regular road conditions when applying the brakes, the pedal seems to go more to the floorbroad than it should before vehicle will stop. When going through inspection every year the brakes pads are replaced twice a year. The rotors were replaced 1 and 1/2 years ago with 27,000 miles. (2) Months ago the brakes pads were replaced and need replacing again. Service brakes, hydraulic
Brake rotor came completely apart. This condition was obviously building up over time resulting in poor brake performance over the years. All rotors should be replaced on these vehicles. It this happened at a faster speed or in an instance where a quick stop was needed an accident could result. You have many complaints of poor brake failure and this is one of the reasons why.
