Three problems related to brake disc caliper have been reported for the 2004 Chevrolet Suburban. The most recently reported issues are listed below.
While approaching a stop sign, I tried to brake and the pedal went to the floor. No brakes!! I was able to coast to a stop. Upon checking, all brake fluid was gone and the brake lines were rotted through. All brake lines had to be replaced along with the front calipers. Corrosion was the problem with the lines and calipers.
Failure of brake line and loss of fluid with no warning light until pedal went all the way to the floor. Mechanic has reported severe corrosion of the brake line, calipers, spare tire assembly and no access to the brake line area above the spare tire without cutting the spare tire holder assembly out. Estimate is over $1000 to repair. Brake failure without a warning - very scary.
The top nut which holds the right rear brake caliber bracket came out on my vehicle. The result caused my vehicle to abruptly stop severely jerking the passengers in the truck. The bracket also punctured several cracks to the inside of my rim causing my tire to deflate. I have never had the caliper nuts removed on my vehicle. The only thing I can think of is the nut must have vibrated loose. The lower nut was loose as well. The loose lower nut was discovered after removing the wheel to repair the deflated tire. The incident occurred on Sunday, October 19, 2008 at 1:30 am. My vehicle was towed home for repair. A new rim and brake caliper nut had to be purchased to repair my vehicle.
