breaks breaks and E-brakes

Ok I just bought my YJ a week ago and one thing that I have just began to notice is my parking break is not doing its job at all. It will work for flat ground but my driceway is a pretty steep one and I found my Jeep in the middle of the street this morning.!!!

So then I started to put it in 4x4 and then it would stay. but tonight it seemed to not want to stay still again. every once in awhile it would jerk a lil and it would move?? this just isn't right.

So anyway I was wondering if this is a envios YJ thing? And what are the ways to trouble shoot this break problem? I have worked with drum breaks once before but never wanted to touch them again. I love my Disks too much on my car.

so please help a Jeeper in need. I'm afraid to park on a hill. Thank God I don't live in SF.

I'd say the reason it stays put in 4WD is because in order to roll it has to overcome the load on the transfer case and transmission, which in turn has to overcome the load of the engine.

You want to adjust the drums through the starwheel adjuster, which you can get to through the backing plate without actually removing the drum.

Jack up the jeep,. Useing a drum brake spoon, turn the starwheel a few clicks at a time. Your breaks will be adjusted when you just barely feel resistance when turning the wheel (brakes not applied).

Hope this made sense.

There was a recall on certain YJs regarding the parking brake.

Fix the brakes. It's not that hard.
Pull your drums and make sure you've still got good shoes left. Then tighten up the adjuster like Drew said. Then you might need to adjust the e-brake.
The YJ has self-adjusting brakes. Go to a parking lot and back up and stop hard. Drive forward and stop hard. Repeat until the brakes firm up.

There is a tension screw on the line, right in front of the driver side wheel on the inside of the frame rail where the EB cable splits to the rears. On that point is a long screw with a nut. Tighten the nut. According to Haynes I think you set the EB [edal to 5 clicks then tighten the nut until it holds. Pick up a haynes or chiltons and it will show you gow. I tried fixing mine because it rolls backwards but not forward, but my nut/bolt is seized, i have to pick up a new setup.

You said it yourself about not having much experience with drum brakes. I fully agree with what Drew stated, however would like to add a bit of advice. I have not had to do this with the Jeep yet, but my pickup I have, and quite often (long story). I suggest jacking the rear up and put jack stands under the axle. I then undo the drive shaft from the rear differential. My reason to do so is the remove as much mechanical resistance as possible. Once at this point, turn the tire and get a feel for the amount of resistance if any the brake shoes are giving. Tighten the star wheel (under a rubber plug on back of brake drum) a click at a time until you feel a slight amount of resistance while the tire is still spinning some. Then do the other side until the same resistance is fealt. By doing it this way you can get the tension very close to even and there is no guess work in it. Even in neutral, you would still have resistance thru the tranny and transfer case and that is why I drop the drive line. It seems like a lot of extra effort, but in my opinion worth it. It only takes an extra few minutes to assure even breaking from the rear drums. Even though a break adjustment spoon is nice and works very well, in a pinch a screwdriver will do the job. Good Luck
