When to replace the brake pads??

[BoomerRoadie]

Ok, I need some more help....

I spoke to my mechanic today and told him I wanted to do my own brake job. He encoraged me and gave me some pointers. The kicker was that he said to fully expect to replace the rotors as they will likely be out of spec. He told me to check mine and see how deep the lip is at the very edge of the disk. Anything at or near 1mm will be too much and require replacement. Furthermore, if it happens to be ok, I need to be sure to use the same exact pads as on there now, otherwise it will squeal a lot.

I checked mine and I'm just under 1mm deep at the disc edge, but the brake light still has not come on. He suggested waiting for the light to come on and when it does, order the rotors and do the job first chance.

This all sounds like honest advice. What do you think? Should I just put this off as he suggested and do it when the light comes on?

Thanks all.
