Sirlono Posted May 9, 2006 Share Posted May 9, 2006 I'd like to check the runout on my brake rotors before I do my brake job. Does anyone have a recommendation on a dial indicator, or is this something you usually have a shop do? Thanks all. Dan Quote Link to comment Share on other sites More sharing options...
cookie Posted May 9, 2006 Share Posted May 9, 2006 runout is rarely the problem. Check out the Stoptech website. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted May 9, 2006 Share Posted May 9, 2006 I agree with cookie. Unless there was an extreme issue with torque when the rotors were installed, any 'warp' feeling is more likely to actually be surface changes in the rotor alloy itself. better to get new rotors usually. check www.stoptech.com the tehcnical white paper on the Myth of warped Rotors (IIRC) Carl Quote Link to comment Share on other sites More sharing options...
Sirlono Posted May 9, 2006 Author Share Posted May 9, 2006 So what I'm understanding is that when changing my brakes, if I'm not feeling any vibration under braking, then the only reason I would need to change the rotors is if they're too thin??

cookie Posted May 9, 2006 Share Posted May 9, 2006 That's pretty much it in a nutshell. I often get away with another set of pads on one rotor. The second set you are sort of taking your chances on. Quote Link to comment Share on other sites More sharing options...
nipper Posted May 9, 2006 Share Posted May 9, 2006 if your pedal isnt pulsing, and steering wheel isnt oscilating when breaking, your rotors are fine. nipper Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted May 9, 2006 Share Posted May 9, 2006 yep - any little 'waviness' look on the rotor will wear into the pads after the first few stops so having them machined flat again, for most of us, is probably a waste of time.money and rotor material.

Sirlono Posted May 10, 2006 Author Share Posted May 10, 2006 Thanks for all of your help. This will save me money on tools and unnecessary machining. Dan Quote Link to comment Share on other sites More sharing options...
