Brake problem that won't go away

[dmonds03]

So here is the deal.. my front left brake pads shift around inside the caliper causing squeaking noise and rattling when I hit bumps.. so I've replaced the caliper, the caliper bracket, the hardware, the pads (twice) and still have the problem.. what I finally realized is that the caliper piston slightly retracts while driving which keeps the pads loose.. in addition, when press the brakes since the piston is slightly retracted I hear a Clank sound of the piston slamming the back of the pad.. now my question is- why the heck is this happening? Its only on the front driver's side.. anyone else have this problem?

Hav'nt had that with mine yet but it only has 20k on it. Wonder if there is a brake line problem or something with the ABS/trac control since they can work independently.

Be patient...there is a 13" Big Brake kit coming out for this truck soon!
