Demon truck

Today, my boy got ready to go to work, in his 95 taco, and it wouldn't move. It has been setting in the yard for a couple of weeks. It is an automatic. I moved it about 5 days ago to mow. I came out after he had cut the motor off. Got in, started it up, put in drive and it won't move. I gave it gas and the back wheels started spinning but the truck won't move. I put it in reverse and it went. Put it in drive and all is good. I drove it about 3 miles and back. Everything is normal. So do we have demons or what could have happened. In almost 60 years I've never seen this before. Any ideas. Don

 

was the front brakes locked up?

 

My first thought was demons, but now that I look at it more, probably messed up calipers on the front

 

sounds like the front calipers just stuck..

 

That was my thoughts to but I wanted a second opinion. I checked the rotors and they are good. They don't even have a step. My thought was backing up unstuck them. Thanks, Don

 

take them apart and put some of that grease they give you when you buy new pads on the guide pins. Or if the pins are worn, get new ones.
