| Post subject: | Recent sticking brake issue |
Hey guys, so I recently got back from picking folks up from my local train station and I've had a strange problem with my brakes. I was stopped uphill at an intersection and when I lifted off the brake pedal and hit the gas, it felt like there was more resistance keeping me from accelerating than usual, and when I had made a turn at the intersection, that resistance kept up on the level road so I pulled over. It felt as though the brake was still applied while I was trying to accelerate, and when I had come to a stop, I could barely get the jeep to move. I'd have to get heavy on the throttle to get it to move and when it did, I could feel the rear wheels jerking and struggling to move along. The traction control, ABS and ESP lights all came on while I was stopped, turned off when I turned off the ignition, then sometimes turned on again when I would worked the brake pedal. I was about to call a tow truck when I decided to grab the brake pedal and pull it up as hard as I could, hoping for some magic to happen, and surprisingly, the pedal moved just a little bit up and I felt something release off the wheels and the jeep was driving normally. So I'm a little uncertain as to what happened and why pulling the brake pedal up somehow did the trick. I haven't checked the brakes myself yet. Jeep has 46k, still on first set of front pads, rear pads changed about 15k ago. NY State inspection performed a month ago said front pads had about 5k left in them so they need changing. Brake fluid level and appearance was good when the problem happened. So before I check the brakes, any preliminary thoughts as to what it might be? Is it the worn front pads, bad caliper, or the brake slides sticking, or something else? |

Hey I've been on this forum for a while but never posted. But when I saw this post I wanted to offer my two cents. I recently had symptoms very similar to yours including the dash warning lights. It turned out to be a faulty brake booster and master cylinder. After having both replaced it seems to have fixed the issue. I had them replaced about a month and a half ago. Worth a shot. Good luck with it. |

Mine's a 2010 Sport. Bought it used in July 2012 with only 8500 on the clock. Now I have about 22000. |

Covered under warranty? |

Just by having the service tech drive it. Originally they thought it was just a linkage that needed lubrication, but that only worked for a day or so, then symptoms came back. After they looked into it more closely and drove it some more, they figured it out. Missed the warranty by 1 month, so it was almost 400 out of pocket. However, right after, maybe a week later, I had the steering angle sensor on the steering wheel act up (made the ESP come on and limited acceleration). They diagnosed and replaced that for free even though the 3 year warranty was up, since I had just been in for service the week before. |

Rudy, any more on this? Did you get it resolved or did it just work itself out? I see another new thread for a 2010 KK with some bogging, poor acceleration issues... |

I've been hesitant to bring it to a mechanic unless I can recreate the problem, but I haven't been able to as of yet. The Jeep's been driving normally since it happened, no loss of power or acceleration issues like in the other thread. Don't know when I'll be taking it in to get checked out, but I'll update whenever I do. |
