Whenever I park on a hill facing upwards, I engage the ebrake and put it in 2nd gear(it will pop out of first). It creeks and very slowly, inch by inch, will move backwards. About 10 minutes later, its 2 feet fartger back than where I parked it. Am I the only one? Why does this happen? It's a bit unnerving. 😅


I find putting it in reverse stops this rolling.

 

No sir. I’ve never experienced that

 

I just put a brand new ebrake cable assembly in. My Jeep is over 6000 lbs and the jk ebrake design isn't the best. It would never hold on its own. I just find it odd that is creeps so much being in gear. The transmission gears must be creeping slowly. Reverse seems to be totally solid.

 

Autos wouldn't apply to this poll, but yes, I've had the issue and the ebrake does suck. I try to chock the wheels or park against a curb. I haven't played much with the gears but it will try to turn the Jeep over as it rolls.

 

So far my e-brake works well, but it does move a little

 

The parking brake will hold on my steep driveway with the trans in neutral, but it does take more pull-force on the lever than most cars to hold on a hill. The gear shift is selecting a ratio of input to output -- Essentially the force of gravity has an easier time turning the engine's crankshaft in second compared with first or reverse. Leave it in six and it will roll back much faster.

The problem with depending on the engine's compression to hold on a hill is that piston rings don't seal perfectly, so eventually the crankshaft turns if the force (from gravity trying to turn the wheels) can overcome the internal friction. The result is that slow downhill creep you noticed.

The trans needs fixing, first gear is probably popping out at other times besides parking on a hill. Best to chock the wheels as necessary until the parking brake is fixed.

 

You can adjust the park brake, its just like any other drum brake and has an adjusting wheel in it, there's a rubber grommet on the back on the back of the backing plate, pop it out and and use a flat tip screw driver to spin the wheel a few clicks, usually have to do it a couple times a year.

 

I don’t have the problem with my ‘08 4 door. I had the brakes worked on when I got it a few years ago. Replaced the rear hubs and new parking brake pads. The e brake is only 2/3 pulled up and I have plenty of room to go. Never put it in gear to my detriment.
