I'm trying to adjust my parking brake, and I understand how, but I'm having no luck loosening up the nuts to adjust the tension on the equalizer. I've soaked it in both WD-40 and later PB Blaster, I've even gone at it with an impact driver and nothing seems to loosen up. I'm just wondering if I am missing something? I'd consider replacing the whole adjuster assembly, but can't seem to find it at parts stores (O'Reilly and NAPA mostly)
It's a 1991 Pickup, RWD, 4cylinder, 22-RE, 1/2 ton
I've tried searching for posts on this, but ca't find anything, if anyone has better luck, I'd be happy to hear where to find it.
Thanks for the replies, I took another look at it, and was able to make some progress, hopefully this helps someone else here:
I removed the brake lines from the equalizer, then pulled the cotter pin and pulled the adjuster arm out (took a bit of pulling, but it finally came out), then used a bench vise to hold the adjusting nut in place, and took a box wrench and a hammer to the lock nut. It took a bit, but it finally spun free.
There was white powdery residue in there, didn't look like the usual corrosion, so I'm wondering if the previous owner used some thread-lock on it?
