86 Ranger Brake Problem

My stepson borrowed my truck to haul some things to the dump. He noticed that the brakes were not working very well and when he investigated this, he found that the driver's side front rotor had cracked at the hub and was loose. He replaced the rotor and pads on both front wheels. Now the brake pedal will not return to the normal position unless you phisically pull it up. The brakes work, but will not release until the pedal is pulled up. I asked about this in another forum and was told that the master cylinder is causing the problem. Is this true and if so, why would the problem occur now when it was fine before??

Yes, it does sound like the master cylinder. The cylinder is most likely leaking internally.

Does the pedal go all the way to the floor?

Check all your vacuum hoses as well.

Not quite all the way, as I said the brakes do work, just very little pedal play and the brakes drag until you manually pull up the pedal

I"ve never seen it but...

It's possible that the master cyl. problem happened first,causing the pads to ride firmly on the rotor,creating heat and causing the crack? Maybe hauling a load was the final straw for the mc and rotor?

just guessing...er,grasping.
