2004 chevy trailblazer_lt
OK so recently I have noticed as I push the brake pedal in it almost feels like the brake lines are expanding. I am sure thats not the case but I am trying to best explain the feeling, almost like a tickingas it goes further down. So I am thinking A)bleed brakes or B)replace brake fluid. Any other ideas? Also anyone have a good procedure to replace the fluid completely?
