2014 Rubicon brake noise

Hi,
Daughter bought a 14 Rubicon with all the bells and whistles. Only has about 3k on it and been in the shop for brakes twice. They tell her all sorts of stories (she's not stepping on the brakes hard enough, it's just settling in, etc). Anyone out there with a similar issue or should I call dealership. Seems like a 35k vehicle would not have noisy brakes.
Any input really appreciated.
thanks

Stock tires and wheels? Might take a while before they're worn in proper but I wouldn't think it'd be all that noticeable unless she's turning 35s+. The stock brakes become less effective with larger tires.

Define "noisy brakes" , my 2014 JKUR makes a binding kinda sound at very low speeds like pulling in or out of the garage but are quiet when applied at speed. Now the braking distance that's another story but, I think normal for this vehicle. There's defiantly a learning curve coming from pretty much any vehicle on the planet other than maybe a 1965 VW Beatle.

^^^ My 2013 JKR, also does this, but only, backing out of the garage!

Are you sure that it's not the noise coming from Hill Start Assist activating/deactivating? Can you be more specific regarding "noise" and when it's happening?

I'm a fairly big guy 6'2" 240 lbs and no matter how hard I mash on them it takes awhile to come to a complete stop from speed.
In the first week or so of ownership my wife and I both almost had several rear end collisions. We were used to the fantastic brakes of the FJ cruiser we had traded in.

We have two other cars and I always have to remind myself when I get in the jeep to give my self more time to stop.
I wouldn't even consider going to bigger DIA tires without a brake upgrade of some sort first.

My brakes make a sort of groaning noise when I back out of the driveway every morning. From what I have read, this is normal on our Jeeps.

My TJ had terrible braking capability, but it did have larger tires on it.
It was almost not safe for highway driving.

My 2013 JKR, has very good braking capability, but mine is a 2 door, less weight than the 4 door, (approx.. 400 lbs.). Plus I have the stock wheels and tires still on it.

As I already mentioned, the only noise that I get from the brakes, is when backing out of the garage, yes that groaning noise.
When applying the brakes going down the road, there is no noise!!!!!!!

Are the brakes just noisy or are the pads getting worn down as well? My JK used to make noises in reverse, only on hills until I disabled hill assist. Occasionally in the winter they still squeak just a little when first back out of my driveway, but nothing serious. I would try disabling hill start assist and see of that fixes it.

Have you ever checked for flash rusting of the rotors? Some vehicle rotors, depending on where you live can flash rust pretty fast especially in areas near the ocean, or from dampness. They will "groan" when backing up first thing in the morning, until the flash rust comes off from braking action. That can be the reason for a lot of "first thing in the morning" braking noise complaints.

Wanna see some bad brakes? Drive my 68' CJ. Everything about that old jeep sucked but damn, it sure was fun to drive. I came to my 13' jkur by way of a lifted 06' Tacoma with 33" MTs. So I think it's fantastic, even with stock brakes on 35s.

This doesn't make a lot of sense, eg the comparison to the FJ. I have read head to head tests where they stop within a foot or two of eachother from 60. The brakes in my JKU work great and stop fast. You may have a brake issue.

It's the ratio of pedal pressure to the amount of stopping force felt. The FJ has 4 piston front calipers, it required far less pedal force for similar stopping power.
There's nothing wrong with my Jk, every JKU I've driven feels this way, it's just fluid dynamics and physics. The Chrysler engineers decided to use the same brake system in the 2 and 4 Dr JK, when they probably should have upgraded them somewhat to handle the extra heft on the 4 Dr.
To the OP, if the JKU is her daily driver she'll get used to them eventually or she could upgrade the pads to a higher friction material for harder bite and less pedal effort.

You may want to get that checked out. Mine is a '12 JKUR with stock wheels/tires. If I get on my brakes very hard, it activates the ABS and stops very quickly. I've even had a couple of close calls at 70mph speeds and it pulls down quickly and confidently. Yeah, it's not a sports car but I don't have to make any special allowances in normal driving.

Wow, Thanks everybody!!
I listened today...I would call it "groaning"...only going from park to either drive or reverse at slow speed. They told her it was normal and it was the rotors "moving"....
I just put new rotors, calipers and pads on my 2500 Dodge diesel and there was no groaning before or after...
I will explore further..

Sounds perfectly normal to me. Its a sound that every vehicle will make if on a steep hill and easing off the breaks easy. Some just do it all the time.

Ever driven a pickup or a surban?

If you are almost rear ending folks because the brakes wont stop you fast enough one might say you have a habbit of following people way to close.

Yeah I've driven all kinds of vehicles I'm not trying to say that the brakes are dangerous but, that the there may be a learning curve to the amount of pedal effort required to stop depending on what your used to driving.
Obviously the OP's daughter was used to driving a vehicle that required much less pedal pressure than her brand spanking new JKUR.
I'm trying to address the OP's concerns with " is this normal" while others seem to defend the mediocre braking performance as if they designed it.

Your right it's not a sports car or even a modern family sedan when it comes to braking performance. We adjusted to the brakes after a few weeks and now know what expect from them.
When we first got our JKUR we were both used to driving an FJ with 33 inch tires, it required less pedal pressure period.Our JKUR is not our daily driver we have two other vehicles and when I drive either of them after getting out of the JK I'm startled when I hit the brakes.
For the OP, what was your daughter driving before she bought the JKUR ? That may have more to do with the braking performance than any mechanical problem.

Not true...her "other" vehicle is a 03 Dodge Ram 3500 dually diesel 6 spd. She can drive anything forward or backwards with the best of them (boys included.

Mine does it as well. Even when backing out of a level garage. Perfectly normal. You're good to go OP.

I just talked to three of my coworkers this morning that own 2012 + JK's, all of them said their brakes groan during low speed application.
Two of them are looking at the terraflex BB kit .

I didn't mean to offend you/her, my apology, I'm on your side.

It sounds to me like they consider this condition normal for this vehicle, Dealerships usually take braking complaints very seriously and probably wouldn't let the vehicle leave the lot if they thought it wasn't performing up to spec.
The stock brake pad compound is probably very hard and a swap to a softer/performance compound pad may be what it takes to eliminate the noise and improve braking performance.

I also have a 14 JKUR, 3.5" lift and 35x12.5x17's and had problems with noisy/squeaky brakes at slow speeds with low miles. After 4 trips to dealership, it was a bent rear axle. Have them check it out.

Has anyone checked the brake pads for lubricant? It might be that the stock bakes don't have a lubricant between the caliper and the pad.

Groaning from rear brakes when backing out of driveway. Just has vehicle checked out by dealership, they told me they all do this. This was disappointing, the noise is very noticeable, and can be heard from 60-70' away. Driveway in cline is slight not major and "groan" only occurs when shifting from Reverse to Forward with slight turn of steering wheel, definitely from rear end of Jeep. Jeep was a Xmas present for my wife, only 565 miles as of 12-19-2014. My wife loves Jeeps, maybe more than me, but I am extremely disappointed in Jeep engineering to have a design like this.

Mine makes the same binding noise but only at slow speeds/stopping. Mainly when I back out of the garage.

There is really no such thing as "mediocre braking performance" in an ABS brake system.
The vehicle will stop in a distance relative to 'weight-speed-direction-tire/road conditions', according to design limitations (& these are NOT racing vehicles).
A four piston brake caliper (FJ) improves standard braking performance slightly because it is 'fixed' & does not need to overcome the additional mechanical forces associated with 'sliding' calipers.
However, both systems will "lock up" based on the same 'weight-speed-direction-tire/road conditions' encountered, at which time the ABS will manage braking events far beyond the recognition of any real or perceived advantage.
