Hey everyone my 01 f150 pulls to the right when going down the road pulls when braking also. I've had my alingment checked and done, in spec. Rotated tires to no avail. When I jacked up the front of my truck I noticed when spinning the tires that the passenger side barely would spin and the driver side would spin freely. I was thinking maybe had to do with the brake hose lines or something with the brakes. Any ideas?

 

Your caliper is sticking causing increased drag

Yep, just my opinion but I'd start with pulling the calipers and opening the pistons up and then resetting the brake pads. As long as you'd be going this far might as well lube the calipers while you're at it. Should be a quick job.

 

Could also be bound up slides.

 

Thanks everyone I'd figure it was probably something with the brakes. I'll have to get her jacked back up and do some inspecting.
