Hi guys, the brake adjustment on my 50 is froze up and i have tried everything except heat to get it to move. I could put a pipe wrench on it, but that would cause damage i'm sure. Any ideas would be appreciated. Thanks,
John

John,
The adjuster on my 620 was frozen. I used penitrating oil, propane torch and a small hammer to tap with for about 3 weeks. Once it started to move, it came out quite easily. Patience, patience. Good-luck then use anti-seize when you put it back together.

John:

I don't know that you will cause any damage to the brake assembly if you force it, but you stand a good chance of twisting off the four-sided head of the adjuster.

I had one on my 70 that was so tight, I heated it red with my acetylene torch, and still I had to tug it one way and then the other for a while. The thread on that adjusting screw is very coarse, so the rust chunks are pretty large.

If you haven't had success with penetrating oil, it's probably time for heat. You can start with propane.

My other one was broken off. They're available new....$39.00.

I've tried to force the adjusting screw on the 50-shaped piece of rust. The vise-grips just slipped.

when i tried to work on my 50 brakes i had the same problem. i soaked the adjusting screw from both sides with p b blaster and soaked the adjusting pins that ride on the grooves that click inside the brake housing, then left it for a few hours and came back and drove the adjusting pins back with a chisel and hammer, then tapped on the adjusting screw from the inside, then from the outside and finally got the adjusting screw to move, and took it completely out (from the inside). i've got everything apart except the lever shaft and the pedal, i've been working on those for a month or better, i've tried heat, hydraulic press, they're locked up tight. the lever shaft is locked up in the housing and the pedal is locked tight to the lever shaft.-----Walt

It sounds like your 50-shaped piece of rust is a lot worse than the one I'm banging on.

Hey Walt, It's not that rusty, if anything it's to oily. It likes to drip on the floor over a few days. I'm going at it with a torch , penetrating oil and a hammer. I guess I'll call it drippy instead of rusty.
