Gotta replace my brakes...how do you know if you should get new rotors as well?

[Aviation]

is it necesary to change the rotors when you do the pads?

if u only do pads, do u have to get the rotors machined?

how can i tell if i should get pads and rotors, or just pads?

pads have a senser that makes a scrapping noise when it is time to change them along with a visual inspection,-the rotors you will need a micrometer to check the thickness -,and a way to spin them and check for being warped, it is probaly best to replace pads and rotors at the same time-plus its cheap enough to do it all 4 wheels, should be under $200 for parts check www.rotorworks on ebay for your year and model
if you only do the pads you need to mach. the rotors but your car may still pull or shake when you apply the brakes
