Ford Repair: brakes, lifetime warr, metal rails

Question
Hi, I have a 69 mustang conv. with a 302. while braking, the car would pull to one side, upon jacking up the car,I found the front drivers side wheel would not spin, I removed the caliper, and the wheel/rotor would spin,thinking the piston was siezed, and finding it fairly inexpensive to replace(with a lifetime warr)intead of repairing the old,I bought 2 new front calipers, Installed them, bled the brakes as well as one person by himself can,I test drove and found that the same wheel was stll "locking up" I am wondering why the piston will not retract...even on the new caliper..please let me know what you think..thanks, Ron

Answer
Ron:

With Ford cars/trucks the pad slides are normally to blame for a binding sensation in the brakes,  The two metal rails that the pads slide on need to be rust free and coated with anti-sieze compound.  This would be the most common cause for your trouble.

Hope this helps
