john g...I lied about brake rotors
More like I'm getting old and forgetty. I was taught to check rotors with a dial indicator as you said. I abandoned the practice shortly after entering the real world of auto repair. When I started out, if the rotors were within spec, I'd leave them alone. Too many customers came back a short time later complaining of squeeking or chattering disc brakes. Turning the rotors always took care of that. So, since I didn't get paid for turning the rotors the first time because I didn't...and I didn't get paid for turning them when I did later because the job was a 'come back', I said heck with checking them, just machine them. No more comebacks, plus I got paid for turning them. I also got paid for re-doing others brake work who also didn't turn the rotors because they measured true, but made noise.
Sorry for my bad memory. Gettin old's a btch.
