'79 ATC 110 brake issue

[pismorat]

The brakes on my 110 will not release once put on. If I put the brake on, it works great, but it doesn't release to the free position. I have to pry the rear actuator lever back with a bar and it will release. I have it all apart and have WD-40'ed it all and it isn't any better, any thoughts what I should do next?

is the brake cable stuck, hard to move, or nearly frozen?

Both the hand and foot lever cables feel good, they move back and forth pretty freely. I think the issue is in the back, like where the linkage pulls the actuator arm and moves the cam. I just don't know what to try and take apart.

Just went and took the whole assembly off, the brake springs are good; with everything off, the cam (that rotates and forces the shoes out) is obviously the problem. It will spin with using the levers, but not spin back easily. How does this come out? It's pivot in in the aluminum carrier on the inside of the frame.

Remove pull arm by removing clamp bolt that tightens it against cam. Spread arm where bolt tightens and remove pull arm. You can then remove cam from outside. It will pull out. Be sure to mark where arm and cam splines mesh so clockpoint will be correct. Some only go one way so check to be sure. Clean everything real good and reassemble with quality grease. Even on the expander cam. Lube cable so oil flows through and it should return nicely.

That did the trick! Thanks for the help 3Wheelers4Life & tecat-z...time to test it out!

Yeah I had to use a punch and to get the cam out of the brake plate on my 250es when I first got it. New grease ans she was good to go.
Glad you got it fixed.
