Just put new rotors on. i have about 1/2 of the pads left but should I replace them or just wait untill they wear out?

 

are the pads worn even? why did you replace the rotors? if they are even and they arent glazed then use em up.

 

ill bet because they were warped...........

To the OP....wear em out..

 

The rotors were terrible and old

 

Whenever replacing rotors, it is a good idea to change brake pads also for 2 good reasons:

1. Any uneven wear from old rotors is transferred to pads, then they fail prematurely.
2. HECK, you're there already. Caliper is off to change rotor. Only takes a few seconds to slap on some new pads. Do you feel like doing this 2x ????


I usually change them due to reason #2

 

Most rotors get warped as soon as you hit them, it just depends on how they're getting worn and the looks of the surface and the amount of warpage.

Depends on what your idea of terrible is... I've seen nasty that work better than anything, and I've seen top performance work like crap.... Hell, I can show ya what old and terrible look like, and still stop like a ****...

 

Then something is done wrong....they should NOT warp...Most common cause of warping rotors is using a impact on the lugs......a impact is not a torque wrench and will very every lug.....

 

A small amount of inherent warping is gonna happen, it might not be noticeable and severe, but it does just due to the thermal expansion from the friction of the pads...
Just the nature of the beast...

 

I concur with replacing the pads. If you went through the expense and trouble of new rotors you must have had serious problems. Pads are inexpensive and that way you know you're starting with all new stuff. Best to only take it apart once and be done with it and you have the peace of mind and satisfaction that you did the job right.
