Generally speaking, No! You can clean them by removing them and using a rust removal solution. Most of the time the rotor is only rusted in areas where the break pads don't touch. In this case, who cares? The breaks work fine. If they are rusted all over, then you can try cleaning them. Don't paint them!! Some website suggest this. First of all the paint probably want last but most importantly the rotor will not be able to release heat as it was designed. You can also have them "turned" assuming you have a good surface left.
depends on the condition od the pads. If worn or have groves etc from the rotors then replace.
when needing brakes do you have to replace the rotors to on a s60r
We need to know the year, make, model and front or rear rotors to answer that one. also need to know if the rotors and hubs are one piece or separate.
If you are wondering whether it is possible to replace one's own brake rotors or not because you drive an older vehicle that need brake rotors replaced, then the answer is no.
You replace rotors when they get too thin, or are warped. They may be to thin to be turned and still alright to use. Rotors do not "have to" be turned to put new pads on.
If the rotors are in good condition, not warped, not scratched, then you can replace the pads without turning the rotors. Inspect the rotors carefully.
Replace the pads, and the rotors. You need to change the brake pads and the rotors.
They need replaced when they wear out.
possibly warped rotors.Feels for grooves on the rotors(when rotors are cool,your rotors should be smooth ) if you feel them you need to replace them,and dont forget to replace your pads too.Worn pads grind your rotors and ruin them.
Most of the time, you can get by with just replacing the pads. The rotors generally do not need to be turned if there is no pedal pulsation or vibration. Rotors will need to be replaced if the exceed the minimum thickness which is stamped on the web (area with lug holes).
your rotors are probanly warped and need refinishing or replacing. Its normal.
You do not need a scan tool to replace any brake pads. The wear is obvious.
