I get on the freeway heading to work after about 15 miles my 02 trailblazer feels like it's pulling a bus..the brake pedal is fully hard, when I take my foot off the accelerater the vehicle drastically slows. When I leave work 8 hours later no problems, in fact it won't show up again for a week or so....any ideas.
Not sure..a couple of days ago my rear pads went straight to grinding, no warning. I replaced them AND the resivoir cap.. it has done again since then and yes it happens on the freeway.
