Two problems related to brakes failed have been reported for the 2004 Chevrolet Trailblazer. The most recently reported issues are listed below.
On Tuesday September 9, 2008 while driving my 2004 chevy Trailblazer and attempting to make a slow left turn the power brakes failed. The brake pedal became very hard to press. This happened on two more occassions I was more than (30) miles from home in the evening about 7pm. On Wednesday September 10, I took the vehicle to ridgeway Chevrolet in lansing, illinois to have them checked. I was told there was no vacuum to the booster. That they had to clean out the plugged vacuum ports. I was also told no parts was needed but the cost would be $240. 57 which I paid. The service order # is 151828.
My daughter was driving my 2004 Trailblazer on an icy, slippery road at 25 -30 miles per hour, (the speed limit is 30, it was the street we live on) when she lost control, hit a tree and totaled ($22,000. 00) the vehicle. The officer and I walked the path in the street and could not find any signs of skidding or braking, there fore leading me to believe now that there was a braking failure. Up until now, when I heard about the brakes failing do to corrosion from road salt, I always thought it was just an accident in poor road conditions. When I first read the report of the investigation I couldn't belive it was the same scenario as her accident. Poor road conditions, therefore possible salt buildup, a slow speed and inability to stop. I am so gratefull that she walked away without a scratch, also considering the air bags did not deploy, even though the front end was totaled. I am sure this is a problem that must be identified for those living in colder, northern states.
