One problem related to brake disc caliper has been reported for the 2004 Chevrolet Avalanche. The most recently reported issues are listed below.
Leaving the yankee stadium parking lot in the bronx . Traffic was heavy! the traffic was stop and go . Upon stopping I felt the pedal go to the floor and smelled brake fluid . I pulled over and notice the split in the brake line near the chassie . I then had the vehicle towed home. The truck is a 2004 chevy Avalanche with 60,213 miles on it. The brake line was split on the driver side chassie. It was not the rubber line going to the caliper but the stainless line feed the system.
