With my 65 I have to pull very hard on the emergency brake handle to get it to hold very well. If I am parked on a hill so it wants to roll backwards, its worse. I have a 4-speed and leave it in reverse. That usually holds it. With it in gear, if I don't pull hard enough, it will groan and creek some and very slowly roll back.
I replaced the handle mechanism under the dash, including the pulley on the end.
Ideas ?
Thanks
