Rotors: Change how often?

I think mine might have 20k or more on them. I replaced them the last time I changed my brake pads - both NAPA brand. I'm starting to get some squeaking on my front tires so I'm gonna change the pads, but I'm wondering if I should (need to) change the rotors too.

 

Nah, just change the pads.

 

Measure them, if they arent warped and within spec then they dont need to be replaced. If they are warped you can usually have them turned down if they havent been turned before.

 

This! They don't have to be replaced if they are within spec...

 

Anyone that needs a write up for brakes I just did one.

if they are flat and smooth you don't need to change them unless they are warped and this is easy to check by spinning them, if it drags in one spot as you turn it then they are warped and need replacing. it is supposed to spin with even contact all the way around.

I saw a chart that said the rotors should be changed every 3rd set of brake pads but I don't pay any attention to charts like that since it all depends on how you drive and the condition of the rotors.

pay attention to the rotor thickness, it should be the same on the inside as the outside and be 3/8" to 1/4" on each side. if its 1/4" you are ok but if its less then 1/4" replace the rotor.
