nah, i put them on myself and have done it hundreds of times and never had any problems, but about 3 or 4 days after i got my truck realligned, they started this. i pulled em back of today and its like brakes are always pushed in a little bit? like, if i push the brakes, they stay pushed down on the rotor even after i let off the brake. could that be because there's too much pressure in the brake lines or something?? i dont know what would cause that.
