We have a 2004 Ralliart Sportback and have had a ongoing problem for the majority of the time that we have had it. Whenever we are in reverse and step on the brakes, we hear a squealing noise that is like running over a cat. It has never gone away and is getting worse daily. Has been back to the dealer a few times and each time they tell me the brakes are fine and there was brake dust built up that they cleaned out and we should be good to go. Yesterday I had it in to the dealer and they gave me the same story about it being dust and cleaned out and fine now. I got into the car after it being at the dealer's all day and drove straight home, put the car in the garage and when I left the house this morning the squeal was back, I doubt it ever went away since I didnt have the opportunity to test it yesterday afternoon. Anybody else having this problem? Any help would be appreciated! I have to have it at the dealer again in the morning, but I did call Mitsubishi today and opened up a case on the whole deal. If anyone has any insight or suggestions please let me know asap. My 12k warrenty is up in about 175 miles and they say they wont cover it then even though the problem has been there all along. Thanks

 

i think our cars just naturally do this. there was a thread on it a way while ago. i dont think it is anything to worry about. its most noticeable in the morning for me. i just think it is due to moisture build up or something. maybe u are experiencing something different though. but yeah, it does sound like a cat being ran over when you put it in reverese and apply the brakes.

 

It's the design of the brakes, there is no way to avoid it. I think it's just the back brakes, it only happens in reverse and usually only happens (or is worst) in the morning or after it rains. I wouldn't bother doing anything. Aftermarket pads may even fix the squeal.

 

Happened to me all winter, all it is is rust build up on the rotors.

 

the squealing comes from the right rear, and it is not the front brakes( at least it sounds like it coming fom the back) and it doesnt happen if I use my e-brake to stop when I back up. When you apply your brakes it is the front brakes that do the work and when you apply your ebrake it uses your rear brakes right? Then why doesnt it get louder when I apply the ebrake? It is getting worse and worse for me. I can go someplace and be in there 15 min and come out, back up , and it does it again ( not as bad though). WTF!!! this is the only thing that pisses me off about my car. A car should not make that awful noise, not new anyways. I want to change out my rear pads but Im not sure if that will help.

Sorry guys...I get tired of people saying dont worry about it. I have owned (my wife and I) cars with rear disc and they never made such a god awful noise. I have 6000 mils on my car not 90,000+ miles. If I did then I might expect it. And the dealers dont give a f**k.

 

Most of the times it happens when your discs get uneven from hard braking and high temperatures.

Get your discs even (I dont know the exact word in english for "rectificar" = rectify = polish) that may correct the noisy squeak.

 

Yup mine does it too. I've heard its something regarding the Anti-lock brakes. Not sure If thats true or not. But rust definitely affects it. A little rain is all you need.

 

isnt it due to the brakes resetting themselves when you travel in reverse? any time the rotors are rotated in reverse the pads reset themselves or something like that? so you have a more even wear on the rotors, i think i remember reading that somewhere on here, could be wrong though

 

yea i got that noise too...it really does get annoying...ive been looking for a way to fix it but havent seen any yet...im hoping that when i get rrm's rotors and some new pads it will stop.

 

when i used to have my eclipse the brakes would skealing noise just like my ralliart, a year later i had to change my brake pads. put some after market one and it didn't make that skealing noise anymore.

 

Thanks...Im gonna try that this weekend!!

 

Our rear brakes use what's called a "drum in hat" setup. Basically, two brakes in one. A disc brake for normal braking with the pedal, and a drum brake for the e-brake. If you look at your brakes, you'll notice the center section on the rear discs is bigger than the one on the front, that's because inside of it is a small drum brake setup. This is good for a couple reasons - e-brake will always work no matter how worn your rear pads are (since the drums have their own set of shoes), and it also helps prevent your rear discs from warping, which would happen if the e-brake was clamping onto the disc.

You may have glazed one of your rear brakes, which would cause squeeling. Changing brake pads should get rid of it.

 

Got the same problem, and if i back up and hit the brakes a couple times it will disapear. I think it has something to do with setting them. A long time ago for my first car, Buick Lesabre, my mechanic told me to back the car up every now and then and hit the brakes, not hard, but enough to use them. Seems to make a difference when I do it. But i do understand the frustration with so little miles on the car!

 

That's only for self-adjusting drum brakes. More recent rear drum brakes have a ratcheting mechanism that, when you back up and use the brakes, moves the shoes to the proper distance from the drum. Disc brakes don't adjust this way, so it won't do anything for a car with discs on the back.

 

Like Otter said, that's only for drum brakes. Disc brakes are always at the proper "adjustment" (the pads are always lightly touching the rotor, even when you're not on the brakes)
Drums have return springs, so when the shoes wear, the shoes are farther away. Backing up and hitting the brakes forces the shoes into the drum and clicks an adjustment wheel.
Some cars with rear disc brakes and an ebrake that uses the calipers uses the ebrake to adjust the calipers (stupid idea).
