I know, some of you might tell me warp rotors, but i just had these on fro 6 months and they are the Rotoras.. My Gs shakes when i apply braking at high speed, but when im at 10-40mph and apply brake, it doesn't shake... I already had a road force balance, so i don't know what it could be, i afraid to change the rotors cause i just had them for 6 months and you know Rotoras aren't cheap either! So please, any suggestions?

 

you can resurface the rotor ($10) and put new brake... just for the front one
Hope it go away.

 

worst part about re-surfacing a warped rotor is that it WILL warp again... when a rotor warps, and it gets machined, you have thin spots and thick spots in the rotor, which when heated, will expand and contract at different rates...

i will agree that you have warped rotors...

 

What year is your car?

 

Its a '01

 

just get them cut, get new pads, and break them in properly. What I have found to work best is to get a couple of 70 to 5 stops, without hitting ABS. Hitting ABS = no good for pad break in. 3 stops like that should do it. If you get caught on a light, try not to stand in one spot on the brakes, keep rolling slowly, that will avoid hot spots. Then park it for a couple of hours to let them cool thoroughly. After don't do any extreme stunts for a week, you will be fine. Also make sure that your lugs are torqued to speck, 80ft lbs on all of them. Make sure your HUB, rotor, and wheel hub are cleen of rust and any other debris before re-assembling everything.

I do this all the time, and my rotors never warp, or vibrate. They last the life of the pads, then I usually just get them cut, new pads, and they last again.
