Emergency Brake Not Working

[gstorek]

The emergency brake on our 1971 280SL is not locking into a "brake on" position.  Pulling up on the handle applies the brake, but it won't stay.  In other words, the brake is working, but it will not stay locked in place.  Depressing the button does nothing.
Does anyone have a suggestion as to what might be the problem?
Thanks!

Maybe the adjustment procedure here will help.  Or, maybe you'll see something else that helps.
