I've never done a mc on a sentra. I've done a few on toyotas, toyotas have an adjustment and sometimes people adjust it to tight and what you're describing happens. I've also seen abs units do similar things.

thanks for the info *** check on that..

You might want to check your brake pedal adjustment. The rod from the pedal arm that moves the cylinder in the MC is adjustable in length. There is a locking nut and the rod is threaded so when it rotates the length changes. Make sure that it's not making the brakes drag when the pedal is not depressed. There should be a little free play before the brakes engage. However, this would not explain why the lock went away without you changing anything.
