i have a 04 civic, and after going fast on the highway and braking, my car vibrates really really bad. but this only occurs after ive been driving around 90 to 100 mph on the highway. during city driving, braking is fine or when i dont speed. anyone know whats going on?

 

what makes you have to go 90-100 mph?

just wondering..........

 

I've hit 90 on the highway multiple times with no problem. Anyway, chances are that your car is vibrating b/c you have runout/warped rotors . All you really have to do is remove the rotors and take them to a machine shop to be resurfaced (like $7/rotor around here). It is also possible that the rotors are too worn to be resurfaced in which case you will need new rotor.

 

ooof if i have to replace the rotor i konw im looking at a lot of money right there.

 

Depends on what you think alot is. I think rotors from autozone are like $20 a piece but i'm exactly sure.

 

right around thre, between 20-30 for decent ones. And its a really straight forward install that can be done in the driveway in an hour or two at most.
