Chevrolet Malibu: Brakes

I'm sure it's rust. I parked my car outside over a weekend of driving rain and the right hand brake rotors were soaked with water. When Monday morning came and I took off with the car, my brakes on that side were so noisy I turned back home. It sounded as if there were no brake pads left. I took the rear wheel off to see what the problem was. The rotor was rusted. I cleaned it off with sandpaper and all was well again. Other than that, my brakes are very good and as smooth as silk. |

My GM/Toyota built Prism had exactly the same problem. If brakes were wet and allowed to dry, the rotors would develop some rust and the brakes were noisy when applied. After a few applications, the noise stopped (I assume the rust was ground off by the pads).

I'm not sure if this is brake related or suspension...or both. I'm having this intermittent annoying problem. Sometimes when I apply the brakes, i get a nasty knocking sound from the floorboards or the front of the car. When this happens it will happen for a few brakings in a row, then I don't notice it anymore. It sounds like rotors, except it is too intermittent. And just last week I did take the car in for regular service and they checked the brakes and other than some uneven wear they're fine. They did do a brake service. I didn't tell them about the problem then, cause it was so intermittent and hadn't been doing it for a while. But now, it does it almost every other day. Because it is so intermittent, I'm afraid that they won't be able to spot the problem. Any thoughts would be appreciated. Joe |

Replying to: calisnshyne (May 26, 2006 11:25 am) I have an '01 Malibu and it did the same thing yours is doing right off the lot with 3 miles it. It kinda sounds like a trolley car coming down the street. khhhhhh___, right ? The car would not stop ! Then the rotors warped after the first 3,000 miles. The dealership gave me a hard time about it and said that GM's fix is to use ceramic brake pads but I would have to pay for the uprgraded pads not the standard pads and they would cut my rotors not replace them. And that the warping problem is due to overheating because of a bad runout alignnment between the rotor and the caliper. The fix for that is to not overtighten the lug nuts and clean and adjust the rear brakes. Isn't that special. |

My 21K mile 2005 Maxx LS has had the rotors turned twice for severe vibration... they warp very easily if you brake hard at high speeds. Most cars with disc brakes will do this eventually, but the Malibu's brakes seem to warp more easily than on any car I've ever owned. I could not warp the brakes on my 1998 Taurus. I've also noticed that the brake's rotors get excessive rust after only one night when put away wet... especially if it is salty wet. This is also much worse on the Maxx than on any other car I've owned. It makes the brakes rub and howl for the first few appications of the pedal. Again, my Taurus never had this issue. I think GM is using some really poor quality material for their rotors. Probably cheap Chinese castings. I'm looking forward to replacing them when out of warranty with something better... maybe something cross drilled if I can find them that way. Meanwhile I'll let GM keep fixing them.

First time poster, long time reader. I've just purchased a set of Pro Stop drilled and slotted rotors to combat the constant issue of warped/soft rotors that GM is put on my 2005 LS Malibu. They weren't cheap, $400 for a set of 4, but I'm anticipating less squealing, longer rotor life and cooler brakes. Plus, they're made not to rust and a nice 12,000 mile warranty. As soon as I brake them in, I'll let you know if they were worth it. |
