E brake releases
Hi All,
This is my first post here, sorry if I have a noob question.
We recently got a '74 F-250, partly a toy for me and partly my son's vehicle to drive.
He has told me a couple of times that the e-brake releases without warning. Today it happened when he was outside the truck so he had some fun unlocking the truck and stopping it before it really got rolling.
I reminded him to park the truck in a high gear ... but still, I am wondering if this is a common problem and what the fix may be.
Thanx in advance,
Lorne

Maybe a worn pawl and/or a fatigued spring in the e-brakes ratcheting mechanism is allowing the pedal to disengage itself....my e-brake hasn't worked in nearly a decade, i've never actually taken the time to check it out.

mechanical advantage works backwards going the other way.
low gear is the easiest for the engine to turn the wheels, but the hardest for the wheels to turn the engine.
high gear is the hardest for the engine to turn the wheels, but the easiest for the wheels to turn the engine.
that's why when you have to push start your truck, you use 2nd or 3rd ... keeps the engine from stopping the truck when you pop the clutch.

try taking the whole pedal assy out and giving it a good degreasing/lube. I had one in another truck that the little part that hooks would get gummed up and not do what it's supposed to.

Sounds good everyone. I will try to get at it this weekend.
meborder, you hurt my brain with your point about the gear when in park ... it is sort of counter-intuitive but makes sense to me now.
