clutch problem 51 ford

[trainguy]

I drove the 51 yesterday the clutch worked great,trans shifted great. this morning it grinds putting it in gear and seems like the cluch is not releasing properly.I put the car on the lift and examined the linkage,looks ok.I took up on the cluch adjustment and the clutch is releasing and it goes into gear without grinding.The clutch pedel no requires much more effort to opperate.My guess is something happened to the pressure plate or thro out bearing.I am wondering what could cause this problem to happen all of a sudden.I am going to order a new clutch and thro out brg assy from Fort Wayne Clutch on Mon.
