#78 of 100 Jeep Liberty rear drums
Dec 19, 2009 (7:42 am)
We have a 2002 Liberty--zero problem vehicle until rear drums quit working. Front brakes lock up on ice, rear wheels keep pushing. Drums have been turned, drums have been replaced, shoes changed twice, proportioning valve checked, all done at my Chrysler dealer. After all this you can slip the vehicle into neutral on glare ice and the rear wheels will not lock up, by pulling on the "e" brake or braking hard. If you set the shoes up so the brakes grab some what, the drums over heat in a short distance. I have only paid for the original visit, given work is warrantee. I know they don't want to see me again.

It seems your brake linings are now too thin and this forces the automatic play limiters (brake shoe rests) to go beyond their normal range. When your drum brakes over heat rapidly this means the brake shoes become "self locking". When you open a brake drum, bring all cams and rests to their lowest position and measure the minimal diameter over the lining of the brake shoes. The drum diameter should be ~1/16"-1/8" larger than the linings. If you have a lot more play, this should be the problem.
Otherwise look at the surface of the brake shoes: rubbing against the drum should occur in the middle, never at the tip where they are pushed by the receiver cylinder.

Dealer has now replaced the master cylinder and the antilock brake control module. Brakes are doing the same thing. Pedal will go to the floor when steady pressure is applied. Dealer stated that they have now checked four Jeep Liberty Diesels and they all have this same symptom.

I have a 2005 Liberty Diesel with the same problem. Dealer has replaced master cylinder and antilock brake control module so far and the same problem exists. They have given up and said it was normal. They have checked 4 other diesel Libertys and they all act the same way. I believe this is a serious problem and will continue to research this.

Update: Check the pedal with no key in the ignition. Pedal is hard, does not fall away. Turn on the key, this energizes the antilock brake electronic module. Now pedal falls away. Problem must be in the electronic module (CAB) or in the wheel sensors. I will be going back to the dealer with this new information. Stay tuned.
#83 of 100 dealer wants to replace rotors
Jan 16, 2010 (8:11 pm)
I just got back from the dealer where I asked them to check the brakes. The car has 47k miles on the original brakes so I thought it was getting close. They told me the front needs immediate replacement and the rear has a few thousand miles to go. Then he told me that they won't replace just the pads anymore. They always replace the rotors at the same time, it comes in a kit. I really don't want to spend $700 for the front and rear brakes.
Does this sound normal? What would be the harm in just replacing the pads?

I had to pay 700 USD just for the front brakes (disks and pads), the labor was covered by the ball joint recall.

Dealer replaced the CAB module. Problem still exists. Jeep is synonymous with Junk!

I've replaced both front & back pads, rear rotors twice and now when I brake, the steerling wheel is once again vibrating. What is wrong with my 05 Liberty? Everything else has been okay so far. I've got 53K miles to date.
Other than the stains on the seats and the brake issue - I've been rather content with my LIberty.
If my problem sounds familiaror there are solutions or explanations, please advise. The thought of spending another $450 is just not cool.

Vibration in the steering wheel while braking is typically caused by a warped rotor. I'm sure that's why the dealer wants to replace them. If the rotors haven't been turned before, having them turned/re-ground will normally take care of that problem otherwise, yes, new rotors are in order. Now with that said, let's talk about causes. It's been my experience that warping of the rotors are typically caused by the wheels not being torqued properly when they are changed. So the next question would be who rotates your tires. I rotate mine every 5,000 miles or so and because I do it myself, I know that I have torqued the studs myself. If you have it done at a tire store, they can be lazy at times and simply zip them on with the air gun and there is no way to have each bolt tightened at the same number of foot pounds. If you do them by hand, then you need a torque wrench to make sure that they are.
Untorqed lugs will cause uneven pressure on the rotor and when you do either a high speed stop or a lot of stop and go, the rotors heat up a lot and when cooling down it will cool down unevenly causing warping of the rotors.
At least that's been my experience in all the vehicles that I've worked on in the past. I've got the same year and about the same miles on my liberty as you do and I still have the factory brakes and rotors on it.
