I don't think there is a exact amount of km's. But when they start to make noise or there is any brake fade, you should have them changed. You rotors only need changing if they are scored, even then they can be re-machined @ a fraction of the cost. this does not always work and alot of shops would rather have you spend the xtra cash on new parts. hope that helps. cheers
I agree with what has been said, but would add that Auto Zone or the others like them, can get you some very, very sweet prices for pads and rotors. I just replaced the rotors simply cause they were so inexpensive; ~$25 each. Easy, easy brake job. 30 minutes a wheel, fronts.
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.
when needing brakes do you have to replace the rotors to on a s60r
depends on the condition od the pads. If worn or have groves etc from the rotors then replace.
You do not need a scan tool to replace any brake pads. The wear is obvious.
Replace the pads, and the rotors. You need to change the brake pads and the rotors.
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.
When applying the brakes; if you feel the car jumping it's usually the brake rotors need "turned". And, all depending on the age of the rotors and how much your OLD brake pads have scraped them, you might need to buy new rotors. So, my answer is TURN or REPLACE brake rotors. <end>
They need replaced when they wear out.
When Brake Rotors Are To Thin To Turn On A Brake Lathe To Have The Minumn Thickness. They Need To Be Replaced.
You probably have a warped brake rotor. New rotors are fairly inexpensive, I would replace both front rotors and brake pads while your in there. The calipers and sliders along with the brake hoses and lines need to be examined also.
probably brake rotors and pads.
This is not much information, but I'll give it a try. If the front brake rotors have too much run-out, "wider in some spots than others" then the rotors need refaced or replaced. If the problem is in the rear brakes, the brake drums are out-of-round and need resurfaced. If you feel the tremble in the brake pedal when you brake, then the problem is certainly in the brake system. ------------ He is correct...the rotors are probably warped. Replace the rotors if they are warped that bad. You can get them turned but they are going to be thinner than new rotors and whatever caused them to warp last time will happen faster. (heavy braking and riding your foot on the brake can cause the rotors to warp)
