Impala 2004 3.4, harsh vibration in my brakes, non ABS, HELP!!!!

[trendkillerchris]

So I bought a Impala 04 3.4 (NON ABS) used starting at 128 000km. When I bought it I kinda mildly noticed a weird vibration on my brake pedal.

I drove it maybe another 9000 km all the regular maintence done tire pressure good. I wanted to try to fix this vibration problem because it was bugging me and it was feeling worse.

I've replaced front brake pads and routers all high end parts. The back pads and routers were fine.

Didn't really resolved the problem but it seemed to help it for a week or two. After that noticed the vibration on my brake pedal to be about the same. So I went and got my tires balanced to see if that would help but it didn't.

So I was really feeling the vibration on my driver's side so I thought maybe it was a wheel barring but found that the wheel barrings were fine but I replaced them anyway again all high end parts. Still hasn't fixed the problem. It's kinda frustrating cause I've thrown about 750 dollars for parts at this problem and still nothing helps it.

This is where I need help, what the hell is causing this harsh vibration on my brakes when everything is fine. Because it is getting worse and I can hear like some kind of clunking noise just when I brake and I feel it pulsating. Oh yeah this car has no ABS installed on it which I kinda thought was funny. Cause I thought most if not all cars had it after 2000

I need some advice or ideas or something. I'll be checking this thread as much as possible because I need to know what the hell this is.

I've checked the threads and I was thinking maybe the lower control arms on the front wheels the rack and pinion or maybe struts? I don't know I NEED HELP!

Can anybody help?

Did you try rotating the tires front to back? Maybe you have a bad tire.

[trendkillerchris]

yup sure did

When you put the front brake rotors on, did they fit snug. I mean, does the opening in the middle of the rotor fit tightly around the hub? If it has any play in it, it will be a problem.

Got me stumped. Bearings, rotors, wheels, tires... and it sounds that you've done controled A/B testing (via repalcement or rotation). Start mounting the mini-spare on each corner, to see if it goes away? If you rotated the tires, would the vibration just move to another corner?

Due respect here, but I would suggest a professional drive this car to help pin down the source.

Vibration always in the front, it has to be something is not sitting right. I'm thinking about taking it to a chevy dealership to get it looked at. Not looking forward to the bill.

Once I find out for sure what the problem is. I'll post it on this thread for future reference
