Ok, so if I understand right, you are saying that brakes are worse than engine-braking because 1) Brakes are more likely to lock the tires up, and 2) When the tires are locked up, you can't steer. Is the same risk present though if you are backing down a hill, and therefore most of the braking is being done by the back tires, which presumably are not used for steering on most rigs? I ask because that is the situation I had in mind when I posed the question. I was recently trying to climb a steep hill and came up to a 4' sheer rock embankment that I simply couldn't climb. So my only real option was to go back down the hill. Not wanting to risk turning around on the side of a steep hill, I decided to do it in reverse. Because the trail had lots of obstacles on either side and was kind of twisty, and visibility in reverse isn't that great, I found that the one gear available to me (reverse) was way too fast, even in 4-low... so I felt my only option was to put things in neutral and ride the brakes haltingly back down the hill. I did that successfully but there was definitely a pucker factor! |

You are lucky to still have a Jeep.....
Even if the lowest gear is too fast, leave it in gear and use the brakes. As long as you are moving, you won't stall out and if you are going slow enough to stall out, then dump the clutch and stop. Reverse can be really snaky. If the front wheels lock up, they can easily slide you sideways enough to flip. If you are in gear, the front wheels can't lock up without all 4 locking so your control stays with you.

Re: Who was it that said I didn't need lockers...?
Joshua,
You did the right thing until you put it in neutral. Leave it in reverse and lightly apply the brakes as needed to slow you down a bit. You stand a much lower chance of locking up a wheel if you are in gear. Any time you lock up a wheel or two with braking, you degrade your controllability. You need to keep all your wheels turning. You were also correct in not trying to turn around. That could have been disastrous. -- Jim -- 98 TJ SE 90 SJ GW http://www.delawareja.com/gallery/JDJeep98 "You can do any job in the world with the wrong tool if you try hard enough..."

Of course, being there is a very important part of this discussion because being there lets you experience a wealth of other variables that make cut-and-dry statements impossible. Basically, my first thing to do ALWAYS is to select the proper gear that will hold me back, and allow me to feather the brakes to "fine tune" my decent. Sometimes I select a gear that is too low, then I use a healthy application of the brakes while shifting to the next gear that will give greater comfort and control while allowing a slightly faster decent. The general rule of thumb is that if you are not comfortable, you are also not being safe. If you are being safe, your comfort levels will increase dramatically. Be safe and comfortable, and you will live to tell the stories. > Is the same risk present though if you are backing down a hill, and > therefore most of the braking is being done by the back tires, which > presumably are not used for steering on most rigs? Pardon me for breaking your thought in two, or more. This is a good question. Yes, the same rules apply when backing down a hill. NEVER EVER UNDER ANY CIRCUMSTANCES FOR ANY REASON WHATSOEVER expect to retain control of you vehicle while backing down a hill and using the brakes. The front tires will lock up and steering control will be lost. It is ALWAYS best if you must back down a hill, to come to a full stop FIRST, and select Reverse, and probably LO range. Do this even if the engine has stalled. Then start the motor and back down in Reverse, If the motor won't start, then back down on the starter motor at least until the vehicle is stabalized to the point that you can walk away from it without concern that it is going to go places on its own. The brakes are intended to stop you while moving forward, they don't work nearly as well in Reverse as in any of the forward gears. The front brakes are metered to take 60% to 70% of the braking load while going forward, they still take the brake pressures in R but the loads are shifted, making the front brakes lock too soon.

I did that successfully but there was > definitely a pucker factor! You need to make gearing adjustments if you can not go slow enough in R. My CJ has a 6.69:1 first gear, and R is similar, maybe even lower, so I can literally get out of my Jeep and walk down the hill faster than it will go on the engine. You would be better off keeping the trans in R, and ridiing the brakes to the threshold of stalling the motor than shifting into N and using the brakes exclusively. |
