can i just buy new pads and put them on my rotors...? or do i need to buy new rotors also....?

 

you can use the same rotors as long as theyre not too thin. But make sure you have them turned before you swap the pads on.

Even that is overkill. Just be sensable on how you bed them in. If the rotors are grooved, then it's going to take a while to match up. If they're in good shape then turning is overkill.

i was given the suggestion of using 50 grit sandpaper on the rotor when breaking in new pads

 

 

Using 50 grit sandpaper is to break down friction material film transfer from the previous set of pads. If you have any grooving on your rotors, you should turn them, and ensure that you are within 15% of spec. If not, then get new rotors. As you turn a rotor down, you are reducing its mass, and thus ability to absorb thermal energy....it will be more prone to warping and cracking.

Here is what I don't want: Someone who turns their rotors and it is right at spec...then installs our pads...achieves better stopping power because of our pads...thus drives the car harders and brakes harder...warped his rotors...blames the pads for the warped rotors. This type of logic = irresponsible bullshit.

Trust me...I've heard all the stories and claims...so nothing would surprise me.

As an aside, the phenomenon of rotor warpage is 100% unrelated to the type of pad compound you are using.
