I've used this method many times, on many vehicles, but I think I need to get someone in the seat so I can eyeball the fluid during bleeding.

There is NO sign of oil or grease contamination on the new shoes is there?
Yeah, I'm with you on ruling out the ABS, given the facts you state. Always figured something in the one wheel, but when I can't quickly identify it, I get off on a tangent. "Squirrel!!"

Don't see any fluid or grease on anything. I've come to the same conclusion, barring anything better, go back and bleed again all the way around. All of the fluid has been replaced in the system to rule out any moisture.

I hear you. I suffer from a character flaw where I find it hard to establish confidence in local mechanics (myself included at this point). I do hear you, and I got a referral yesterday to someone. If bleeding craps out, that's probably the next stop.

Bleed sequence:RR, RL, FR then FL. Start furthest away and go in sequence with next farthest from master cylinder. Use 2 man method with a brick under brake pedal so you don't exceed plunger travel and blow the seal. Don't be afraid to use a whole pint of fluid.

I'm not saying to worry about the bleeding. I'm saying, if you crack open that bleeder (not full open), and use the hose/bottle to catch the fluid, does that corner still lock up when you run the truck on jackstands? If so, you may have a mechanical issue (seeing as you have reduced the wheel cylinder pressure by cracking the bleeder - only way it would lock up is if the shoe moved a little then grabbed, like it shouldn't)

Yikes I know and he knows proper bleeding steps but I found the switch prevents lockup and or unlocks it. I have experimented with many different bleeding procedures and found it works on the Dakota.

Be open to changes it has something to do with the anti-lock braking system (ABS).

Sorry, I didn't get pics or anything this weekend. Other life priorities, unfortunately. Let you guys know if I have any success.
