Two problems related to brake drum have been reported for the 1999 Chevrolet Suburban. The most recently reported issues are listed below.
Brake system fails when panic stop attempted. Brake pedal goes down but wheels keep rolling; no skidding noticed.
The braking system in this car is totally inadequate to provide safe braking. Far too much pressure is required to reach maximum braking. Chevrolet service techinicans say the problem is that the rear brakes often lose tension and hte vehicle becomes totally reliant on only the front brakes to stop. This is exceptionally dangerous. The car has been in for service on the brakes at least a half dozen times, with temporary results. Chevrolet technicians say the brakes are the most commonly complained about feature of this car. The 2000 model year has a totally redesigned and more effective rear disc system. The models equipped with ineffective rear drums should have a required rear disc retrofit or other permanent solution.
