Parking On An Incline

All,
Looking at purchasing a JKUS or R. I live on a street with an incline. My neighbor owned either 2015 or 16 JKU and had difficulties with the brakes when parking on the street. The braking problems always occurred when the front of the JKU was facing down hill. He could not get the parking brake to release or the transmission to go into gear. On a couple occasions a flat bed had to come and take the JKU to the dealer. Other times the neighbor would get his other SUV and push the JKU backwards to relieve the pressure on the parking brake or transmission. Does parking on an incline cause a problem with the parking brake releasing or the transmission going into gear? Thanks in advance for any and all comments.

Pretty sure I know the "issue" you're describing, but it only happens when NOT setting the parking brake properly on an incline.

Don't do it right and you'll have some tension on the drive train, enough to actually hear some grinding when you put it back in gear. Do it wrong enough and I'm sure it would cause some more issues. On top of that, if you use your parking brake off road it can eventually become less effective and need to be adjusted occasionally.

On the other hand, I set my parking brake BEFORE releasing the brake pedal, and never have an issue as long as I do it this way. I also check occasionally to make sure the parking brake is working and actually stops the vehicle.

There is no mention of transmission type in either of the two previous posts.

It sounds like the issue is having a load on the parking pawl in the automatic transmission.
However, phrases like "the transmission to go into gear" and "hear some grinding when you put it back in gear" make it seem as though they could be talking about manual transmissions.

rcantrell52 and chitown35, what type of transmissions do you have?

Easy. Park downhill, wheels turned right into curb. Parking uphill, wheels turned left and backed into curb. Let vehicle settle against curb. Apply parking brake. Shift trans. to P

Minus the curb thing if it's a driveway...

The JKU that I reference had an automatic transmission.

I have not read any post regarding the parking brake failing to release when it's applied with the nose pointing down hill.
Most people have problems with the parking brake not holding hard enough.

If the vehicle is parked on an incline, and the transmission's park pawl is what's keeping it from rolling away, it will be hard to move the lever out of Park. It's not good for the pawl.

Similar to what chitown describes above, I apply the parking brake before releasing the service brakes. I don't put the transmission into Park until I can see it won't roll onto the transmission's park pawl.

Follow Ron on this one! Its all about securing before releasing current brake. That applies coming off too which is why you have to have service brake down before pcm allows out of park. Not sure about the not releasing parking brake thing either.

In a sloped driveway situation you will need a perfectly functioning parking brake to keep any load off of the park pawl on the auto trans. Or a wheel chock.

Like they said, always set the parking brake with foot firmly on the brake pedal before putting the trans into park. Put foot firmly on the brake pedal before shifting into gear and releasing parking brake. The issue many of us have is the parking brake does not hold well on an slope.

Yes, it is easy. But, a lot of people try it to no avail.

I adjusted mine once 9 years ago, and twice since, at rear brake changes. (Had to back them off to remove the disc/drum.)
