Do ya think that if one rotor is bad ... That I would have to replace all of them instead of just the one ... And I got new break's this summer and I think that they have a warannty ...

I've done one rotor lots of times you'll be fine

I concur with Rob that it just only depends on where the metal rivets dig into the rotor one a disc on one side only wears out more than the other side It is best to replace the brake pads on both sides at the same time though and if you see no scarring on the other side then you're good shape

Do them both. Front or back. Consistency is key to maintain your vehicle and its safety.

Is better change the two rotors and brake pads.

Hey brothas ... Thanks for the info ... But situation is in the front on the passenger side... Not cool ... But im guna get a handleon it tomorrow ...
