A couple weeks ago the truck was pulling hard to the left, when I stopped I could smell that the brakes were hot, the driver side was so hot I couldn't put my hand close to the wheel... before that happened when I hit the brakes the whole truck would bounce and hop real bad a couple times the ABS would engage and the ABS light would come on for a moment... so after the drivers side locked up a little like it did, I replaced the calipers, disks and pads thinking that the driver side caliper was bad.. while bleeding the lines, the driver side bled perfectly but the passenger side didn't blow any air and was hardly bleeding anything out. So after replacing all of that, the results are the same, bouncing and hopping when I need to stop? Any ideas would be greatly appreciated

 

I wonder if it could be bearings?

 

Replaced the bearings on both sides

 

Did you replace the rubber lines going to the caliper? Sounds like you might have one with an internal failure.

 

And yes your line sounds like its in trouble sometimes they fail and act like a check valve .
To be clear after a brake job the pistons had been out and you pressed them back in . Well they are composite and absorb moisture so they stick intermittently overheating the wheels and bearings . I fought this for awhile redoing brake grease and cleaning until I discovered the only way to fix it was replace both brake calipers-- rebuilt .
You also may need to fully replace the brake fluid to get all the old junk out of there . When you press them in the dirty stuff goes back into system .
This heating can ruin your new bearings and warp your rotors .
