LumiDriver Posted September 7, 2006 Report Posted September 7, 2006 Well, I just did the brakes on my car about 1.5 weeks ago. We all know that I eat through the cheap 9 dollar white box specials once a month. With the new pads on, the brake caliper is scraping against the rim, bad. As soon as I touch the brakes, it starts to do that. Originally, it did it on the passenger side front, now it's doing it on the drivers' side. I have no clue what it could be. I've done brakes many many times before. Basically, I'm guess that the caliper is moving when the brakes are being applied. (Tim can quote me on how bad it sounds). It's to the point to where when it starts scraping, you can feel it in the entire car...like I was pressing on the brakes harder, then letting off, and then harder..etc. Anyone have the same issue, or at least have an Idea on what it could be. Did I freeze a caliper and it just not functioning correctly? Maybe Tim and I could get some audio of it. Quote
Crazy K Posted September 10, 2006 Report Posted September 10, 2006 I don't want to touch this! but *sigh* here goes. sounds like something major may be wrong, but lets start at the beginning. front or rear brakes? do you have the proper rims mounted on your vehicle? caliper contacting the rim means something AIN'T right. are you sure the noise that you think is the caliper on rim is not really the pad or caliper on the rotor?

LumiDriver Posted September 10, 2006 Author Report Posted September 10, 2006 Well, it's the right front. Disc brakes in front, drums in the rear. I am 99% positive it is the caliper rubbing against the rim. There's scrapes on the rim and the caliper, and they match. The rims are the stock steelies that came with the car. 15" on the tires taht are recommended by the decal. Quote
Cam'ron Posted September 10, 2006 Report Posted September 10, 2006 silly question but is it possible you could have installed the caliper backwards? not familiar with the brake systems on these cars... havent touched them yet Quote
LumiDriver Posted September 10, 2006 Author Report Posted September 10, 2006 Not possible for the caliper to be installed backwards. I've done brakes since before I could actually drive. this just completely boggles me. Quote
Cam'ron Posted September 10, 2006 Report Posted September 10, 2006 hmm honestly that was the first thing that came to my head when you said you were running stock rims/tires... the calipers are installed properly though correct? i guess they would be, prolly only one way to mount them Quote
ToroToro Posted September 10, 2006 Report Posted September 10, 2006 Slide bolts lubed up okay and not rusty or broken? I assume the pistons compressed in fine before you put the new pads on? Quote
Crazy K Posted September 10, 2006 Report Posted September 10, 2006 show us pics of your rims. I think the issue is incorrect rims at this moment. Quote
LumiDriver Posted September 10, 2006 Author Report Posted September 10, 2006 Only thing I have at this time I would think the same thing about the rims, but the thing is, it never did this until I crossed over 65k. Quote
joey b Posted September 10, 2006 Report Posted September 10, 2006 not sure exactly where it is scraping, but I once had this happen and it turned out I had lost one of the bolts that held the caliper bracket on. Quote
LumiDriver Posted September 14, 2006 Author Report Posted September 14, 2006 AHA! I got it fixed. Wrong size rotors, one of the calipers needs to be replaced, and it was seated correctly. Quote
Crazy K Posted September 14, 2006 Report Posted September 14, 2006 AHA! I got it fixed. Wrong size rotors, one of the calipers needs to be replaced, and it was seated correctly. What??????? the picture you showed us in of a non-W body rim. IIRC those are bonneville/old 88/98/lesabre type rims. If those are the rims on your car, no wonder they lack clearance! HOW can your car have the wrong size rotors? pics? Quote
LumiDriver Posted September 14, 2006 Author Report Posted September 14, 2006 the police station that had the car first put them on, and I assumed that they took good care of it. Apparently not. I have the 10 1/2" rotors, when it calls for 11 1/4" rotors. And I figured that pic wasn't of my rims. I can get one up tonight, even though I figured out what the problem was. Quote

Well, its good that you got it fixed! First thing, police stations don't take care of cars at all! I thought all people know that! Second, yeah mid-95 was the change over year to 11.25 rotors. 96+ all got the bigger rotors Quote

I see my local cops having their Impalas at my local Chevy dealer for maintenance almost every time I end up having to go there. Quote
FordBoy Posted September 15, 2006 Report Posted September 15, 2006 my rotors had something similar but my issue was the bolts that hold the caliper on broke so it scaped the fuck out of the rim. 1 side came off the rotor and just scraped. it sucked Quote

Just because they go to the Chevy dealership doesn't mean they do maintenance on time, it just means they know how to spend taxpayers money. Also, cops beat the piss out of their cars whether or not they do regular maintenance. Quote
