My passenger side rotor is grinding against something when I drive it. Rotors and brake pads have just been changed but still having the problem. 2003 buick century...Any suggestions?

Did you check the rotors to see if they were cracked or 'thin' ? Rotors sometimes get really thin with use.And they can crack. Or as in one case that I know of there was sand between the rotor and the pads. The pads were also new. Removed the gravelly sand and they worked fine.

first you put the car on stands and and then you take the two bolts out in back of the caliper and remove the caliper and then remove the pin in the center of the rotor and the nut and then take the rotor off and do not forget to repack the bearing with grease and then put it back together take one side apart at a time.just in case you need to take a look at how it goes back together

* All brake rotors have a discard dimension cast into them. Replace any rotor that does not meet this Specification. After refinishing the rotor, replace any rotor that does not meet the minimum or discard thickness specifications.

sur it is a grind and not like the ABS is going off which could mean a sensor is bad or dirty .more like a pulsating growl

Rust build up is commonly found on the hubs sandwiched by the rotors/hubs
