Maybe they didn't clean them out totally.

The smallest chunks of grit, in the wrong spot, can cause lots of noise in ac drum brake.

Drum rears are kept in adjustment by use of the parking or E brake so if you are running a non 4x4 Patriot you should be using the parking brake often.

Also, braking while going in reverse helps...in some matters helps a lot.
Find a open lot, empty parking lot or a field or back road with no traffic and do some significant brake applications from reverse...I do that monthly.

for now, if you can get your drums off, inspect, clean (air and flushes with brake cleaner...do not use a solvent propelled "fix in a can" like WD40 or any sort of lube.)

!!!

then do the reverse thing and from that point on use your E brake or parking brake, doesn't have to be every time, just regularly.

 

Thanks for the quick reply.

It's a standard, so the e brake is well used.

It's 35 and raining here right now, so I'll either clean them out today if I feel up to it or give it a shot later this week. Looks like highs in the thirties, but at least no rain.

Thanks a lot,
Tyler

Edit: I thought the ebrake on the patriot was independent of the rear brakes? Or is that only the case with the disks?

Well, now, I really don't know that.

its just what I have always known, you know?
drums = E brake adjustment.

I can't see Jeep re-inventing the method but you never know, eh?
Perhaps one of the more knowledgeable folks will help us both out here...

 

Aren't the rear brakes on a Patriot disc or is that just in the later models?

 

From what I gathered from previous discussions, I think Limiteds and 4wd get rear disk, so it's only us FWD sport owners that get rear drums.

Except for 2007, which seemed to have disk on all models.

 

Sounds like the brake shoe dust is accumulating up in there and causing the noises. You should be able to pull off the wheel and drum and flush with water or brake clean. If it keeps happening, perhaps some new shoes might be in order. Your factory ones may have over heated at some point and broke down the binders/glues of the pad material, causing them to wear faster (and thus generate higher then normal amounts of brake dust).

 

Thanks for the suggestions. Finally got a chance to clean out the brakes. Didn't seem like there was too much accumulated in there, but used some brake cleaner and now everything is quiet again. And $150 cheaper than having the dealer do the same thing.

I imagine it'll come back, and at that point I'll either clean again or try some new shoes.

 

Have put new shoes from advance and they are louder than the factory shoes, has anyone tried the Wagner Thermoquiet shoes?

 

My Patriot brakes have squealed in reverse since I purchased it new in 2013. Noise began 1 month after I bought it. Eventually noise progressed to a different type of braking noise in drive as well as in reverse. Been in the dealership 5 times so far - no long term solution has been offered or found. They just tell me "some brake noise is normal." Obviously, I completely disagree. I have never had this problem with any other vehicle I have owned, just with my first Jeep purchase.

 

I've had the problem you guys have, too. When I took it to the dealer they said there was dirt in there. They declined to clean it out because they said it would happen again, and I'd be upset with them. Mine is a FWD that spends most of its time on paved roads. I might go a dozen miles a week on dirt roads, and a couple miles a year on trails.

I got my brakes replaced about a year ago and for a while they were OK, then the squeak came back, but for me its only under heavy braking. I haven't heard the squeak in recent months, in fact until I read this post I'd forgotten about it. I don't know if you can blow it out or wash it out, but as I said, I did nothing and it went away on its own.

 

There is a big difference between never goes on a dirt road and 12 miles a week on a dirt road. It only takes a quarter mile on a dirt road to cover a car in dirt, especially if you are following someone. I'd just take it apart, clean it all with brake parts cleaner and see how long it lasts.

 

Mine is less than a month old, has less than 1,000 miles. I just started getting a squeak over the weekend. Got it when it was raining and the other time was first thing in the morning. Very loud and annoying, but just two times.

 

if they are rusty, they can get really loud. pull your hand brake for a few seconds lightly to rub off the rust on the drum.

 

For the record, I'm still in the back brakes every few thousand miles doing a full clean with brake cleaner (at around 90k miles these days). At this point, I'm going to ask my mechanic to just go ahead and replace them; hopefully new shoes will be enough to offset the frequency to something less obnoxious. Right now, like every month or so, the squeal is present with nearly any amount of braking.

 

I hate to bump this guys: but I just bought a new 2015 patriot sport. I hate drum brakes, so I was wondering if anybody had attempted to convert the rear to disk?

 

I haven't heard of it before on a Patriot. IMO drums brakes shouldn't come on ANY vehicle nowadays, but Chrysler is cheap. It seems that Jeep uses the same brake master cylinder for both drum and disc versions. (some manufacturers use a smaller master cylinder if you have rear drums) I guess all you would really need is the caliper mount, calipers, and some other misc. It should all be interchangeable between the MK family. Go out and find some stuff at a wrecker and try it out!

 

I don't know what's wrong with drum brakes. I punched the brakes last night to avoid a deer and managed to chirp the tires at 45 mph. I had plenty of time to spare.

 

My brakes have squealed when cold since new. I take it in for service from the dealer every 5000 km, and they spray some kind of lubricant on the drums which quiets the racket for a few hundred km, then it comes back again. Other than the noise, it hasn't done any harm. At 65,000 km, the brakes are still better than 50% left on the shoes.

As I said, they squeal when cold. After using them for a few minutes, the noice stops.

 

The rear drums on my 2014 pat have squealed from day 1, dealer even replaced drums, but they still squeak,but not as loud. I did try the reverse thing and e brake,that works for while but that squeak returns.

 

New patriots don't have drums*, unless you have a 4x2(you probably do)? They make antisqueal sprays I believe you could try that or have you tried a brake bedding procedure?(that might only be for disc brakes?)

*For the 4x4 new patriots the parking brake is on the inside of the rear rotors similar to a drum brake.

 

My 2014 with rear drums has not had any brake noise problems at all. My last 3 short wheelbase Caravans also had zero problems with rear drums. It's interesting that some people have problems and others don't. We have horrible salt laden slushy roads 5 months a year also. I wonder what the difference is?

 

I've had a squeak off-and-on since early on, but only when braking sharply at low speeds, like a quick decision to stop for a changing light in city traffic. My dealer said dirt gets in there easily and causes the squeak. They declined to fix it because the service manager said all they could do was clean it out and the squeak would be right back as soon as it got dirty again, and I'd be right back in her face and she didn't want that. Can't say as I blame her. And indeed the squeak does go away, I'm thinking for several thousand miles, but it does come back again every so often. I don't usually hit the brakes that hard so I hardly notice it.

 

Squeeky brakes solved

Jeep is aware of the issue and is not committing to address it! After painstaking effort, I ordered a set of organic rear shoes from Napa at a cost of over 100 bucks. Have installed and no longer have issues. I tried 2 sets of aftermarket drums, 4 sets of shoes, including dealer shoes, along with hardware kits and slave cylinders. Semi metallic rear shoes flat out dont work!

Only thing is that semi-metallic compounds actually work the best for anything but racing conditions and a majority of people do not have this problem...are you sure it wasn't something else you bumped/jostled/etc while you were doing your brake job? Non-rubber swaybar bushings are known to squeak unless wet or lubed just right. Didn't do any work on those recently? Also I think it might help if you sprayed down your suspension with fluid film or something similar. Our '13 had obnoxious squeaks that would even happen at the application of the brakes because the weight transfer would move the suspension. I sprayed everything down with fluid film and the squeak went away after it had a day or 2 to creep.

Edit: fluid film doesn't recommend being applied to rubber as it swells.

 

Hey all, just an update about a year later. I'm still fighting this, and have to clean out the rear brakes around every oil change or so, and the noise makes phantom early appearances when it's humid or raining.

On the flip side, there has been an unexpected positive from this - I have over 100k on my original brake pads (all four, not just the rear shoes) and a few garages have told me that the front pads are starting to get close enough to keep an eye on. The stressful fear of inducing the horrible screeching sound as I approach stoplights and intersections has subconsciously trained me to rely on rev matched downshifts, I guess.

So my 2010 has 106,000 miles today and still on the original brake pads. This car may seem a little cheaply made, but in a hundred thousand miles I've replaced a gas cap, a thermostat, and a handful of sway bar bushings, and still manage above 30 mpg despite spending a lot of time with the gas pedal on the floor. So after six years, really starting to love this car.

 

Old thread but very timely in my case.

Getting ready to sell my '05 Dodge Neon which i had stored in my barn for a year or so.
Brakes worked fine before i stored the car.
Went to pull it out of the barn for a test drive and then a clean up...
......loud brake squeal then finally the left rear brake 'locked' up solid. The wheel wouldn't budge.

Long story short, the brake shoes rusted off their metal support plates and jammed into the drum.
Had one heck of a time pulling the drum off.

Then pulled the right drum off and the shoes were also just about to fall off their support plates too.
Had to do a complete rebuild on both rear drum brakes.

IMO, take brake squeals seriously, especially drum brakes.
No more vehicles for me with drum brakes, ever!
