ok guys this thing is pissing me off, i was driving home from school and my truck (94 SILVERADO 2500) felt sluggish, thought id check it out when i get home, 3 miles way from home my truck start shaking like crazy while braking and i barely stoped, it felt like the tire on my passenger side was oval shaped?? so i pull over and threw it in park, get out n see smoke comming from the passenger side brake,i let them cool and drive home with my hazards on, was scary. i tried everything, filled the brake booster with new fluid, i bled the lines like 5 times, checked the pads(still ok but need replacing soon) every time i bleed the lines and take it for a spin it will work perfectly for about 10 minutes and then the brake peddle gets really hard, and the truck feels sluggish, feels like the brakes stay on just a tiny bit? do i need new calipers? this is my only form of transportation for school and work. Damn im not tryin to take it into the shop eather cause there gonna charge up the ass, what does the problem sound like to you guys??
