My anti-lock break and break light came on. What could be wrong with it? My friend i said i need new rotors, could that be it?

 

how do your breaks feel. is your break light on too. also do you have any issues concerning your speedo or anything. bc sometimes a speed sensor in the rear will kick on the abs light. needing new rotors most likely will not throw an abs code.

 

My breaks kinda squeak when i break really hard. But, it doesnt sound horrible though. My break light is on too with the ABS light.

 

problemly the rrw thingy on top of the back diff

 

thats what i was leading too but he hasnt given enough info to narrow anythign down

 

what rrw thingy?
