Abs system shorted out and would remain on even after engine was shut off. The abs pump and control unit had to be replaced. (not under warranty)was told this is a known issue.
The brakes o my 2003 ext. Trailblazer are mushy. When stopped in traffic and constant pressure is held on the brake pedal the pedal continues to go toward the floor. I was shown another ext. Trailblazer at the dealers that had brakes acting the same way and I was told it is normal. I have had several SUV's and never experienced this type of brake performance before. In close traffic, I have put the transmission in park due to the feeling that I am going to run out of pedal travel.
