The brakes on my Power King barely engage so I would like to adjust them. However, the threaded adjustment piece is a little corroded and locked. 


I tried putting PB blaster on it. - still wouldn't budge


I heated up one side of it, and got it to turn about  a quarter turn. However, I can't get it to turn any further, and go back and forth .25 of a turn and that is it. 


Any ideas on how to get it to move the rest of the way?

If it's rusted bad enough, I have had to go 1/4 turn at a time if necessary. Meaning heat it up and turn it 1/4 heat again and turn 1/4 turn and then back 1/2 turn....eventually it may go

PB blaster and other sprays that loosen frozen connectors take time to work.  Usually days and sometimes weeks.  Keep at it.

I just got a frozen drive shaft yoke apart yesterday. I've been heating & soaking it for almost two weeks. Try to keep your heat focused on just the outer part & not everything. Patience works the best on these jobs.

I've had the best results with a 50/50 mix of ATF and acetone as posted a coffee can or what ever leave it for at least 4 / 5 days.

Lay it on an anvil so you can roll it while wackin it with hammer right where you've been putting the pipe wrench, this will stretch the outside piece and chrush the crap, go all the way around so it doesn't get out of round. put the pipe wrench above were the threads are, a pipe wrench over tight threads just gets tighter

Years ago I foolishly over-loaded a grain trailer-98,000# net-and, even stupider, in the dim light of pre-dawn, elected to park in the huge parking lot across from a coffee shop in Stanfield AZ. Huge mistake. It was actually a well cultivated, harvested cotton field, Nothing but powder a foot deep. 

Only wrecker available was a small home-made type. When it showed up I nearly laughed. Compare to a GT trying to pull a CAT earth mover.

Tractor and trailer were heading back to the pavement when it bogged down, but a good 100 feet away.

"Don't worry, I'll get you out", driver said. "When my front axle hits the ground, that's all you've got."

He was right. Put a snatch block on my bumper, ran his cable out, winched it in...Lifting his front axle up about 5 feet.

Told me to use lowest gear and when I stopped moving that would be it. Not to try going any further.

Long story short, averaging 6,8-maybe 12 inches each time, it worked.

He only charged $50 for the 3 hour effort.

Bit off topic, but, a few will realize the point.

Patience...as long as there is a bit of movement, take your time and work it back and forth, ATF/acetone-as suggested by MNGB works and less cost than commercial products.
