Well guys and gals,those smarter than me and any others willing to listen,here we go again. Problem: Truck was pulling to the left when I applied the brakes.Not at any other time. Solution: Went to parts house and purchased 2 new calipers(1 for each side, duh) and installed. New problem: Now my rig is pulling to the right. The more brakes are applied the worse I have to fight it. Could I have got a bad caliper or am I missing something? Solution: ?????? Thanks to all who reply,ie. wrenchheads! So addicted it's not EVEN funny!!!!
