Car Vibrates...new rotors..need help

[zainiboy]

ok so i have an 07 altima and i kinda bought rotors off of ebay(slotted and cross drilled)...now i took my car to the school workshop and i took my rotors off and replaced em with the new ones...i also changed the brake pads....now when i brake...not just my steering wheel and break pedal but also the car vibrates too....it doesn't stop smoothly...it stopes like if ur taking ur foot off the brake then on it then off then on...like that kinda vibration....any ideas wat went wrong?? i installed the rotors myself..also when im like slow at like 15-20 mph i can hear a little noise like brake pads scratchin against the rotor and when i brake at abt 15-30 miles that noise gets louder..

Same thing happens to me, but im on the stock rotors.

I lost my license for 4 months, so the car was rarely driven. Then i broke my ankle and that was another 4 months it wasnt driven. I didnt even start it one month.

I know something has to be wrong with either my rotors or brake pads. i took it in for inspection and the guy said everything was fine. He said i may need brakes next year?????

Check to see if the rotors are warped - it was ebay after all.

Did you bed the brakes too?

ye sounds like your rotors are warped. they just need to shave em, cut em even. you gotta go to a good brake shop for that though
