I worked for several years in a Sears Auto Center and what I have seen would scare the BeJeezus out of you. One particular incident involved an early 90s model Dodge Shadow. The lady brough it in complaining of a noise in the right rear (disks front/drums rear). My brake tech started the inspection, then called me into the shop. When he removed the right rear brake drum - the entire assy fell out. That was the shoes, fastening hardware, ebrake er bar, and the adjuster. The drum was badly scored from the er bar being between the shoe and drum (for some time). That was the noise she had heard. The tech then led me to the right front (disk brakes right?). He asked if I noticed anything amiss - after some looking it hit me - there was NO disk on the hub. There were no pads in the calipers either for obvious reasons. The pads had been worn down to metal-on-metal and acted like a lathe and had cut the outer part of the disk loose from the hub. We found the disk inboard on the right drive axle. Further inspection revealed that the left front disk was nearly cut off also. Only the left rear brake assy looked normal. After I wrote up an estimate the response I received was - "Just put it back together. I can't afford that much to get it fixed". Fortunately, Alaska law allows a shop to refuse such refusals. Also, there was no way we could put it back together in light of the damaged parts. Dave D |

Re: Loud Civic brake noise
Thanks for the warning. I went to change the front brake pads last
night though, and was surprised to see them in pretty good shape. The right side showed some uneven wear, so I did install new ones. The rotors looked good too, still plenty thick. I didn't experience the noise at all yesterday (even before installing the new brake pads), so I am unsure if a problem still exists. One thing to note, the pad itself looked like it had some rust starting to form, is this normal? I'm thinking about taking it in to a shop this weekend, unless there are any other ideas for something I can look at first.

They *really* need to be lubricated every time the brakes pads are changed. I neglected them once on a Volvo and the brakes ate through a pad and into the brand new rotor within a month (sob!). If the pads are worn at any angle at all, or if there is visible difference between the inner pad and outer pad on the same wheel, that is why. Mike |
