JOEYD2005 Posted May 29, 2008 Share Posted May 29, 2008 I recently replaced rotors and pads on my 96 LS400. I used cross-drilled & slotted rotors and oem ceramic pads. When applying the brakes I am hearing a humming noise from the passenger-front brake. Any ideas as to what could be causing this? Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted May 29, 2008 Share Posted May 29, 2008 I'm not too experienced with drilled/slotteds but I think they make a little noise. My buddy has them on his vehicle and they don't seem as quiet... but you say it's eminating from the FR brake... I'd assume it would come from them all... are the FR pads seated properly???

How would I determine if they are seated? Quote Link to comment Share on other sites More sharing options...
jcrome04 Posted May 29, 2008 Share Posted May 29, 2008 Did you use any grease or shims or whatever Quote Link to comment Share on other sites More sharing options...

CUMan Posted May 30, 2008 Share Posted May 30, 2008 I installed slotted rotors (Powerslot) on my 93 LS about two years ago. The humming noise when stopping was immediately noticeable and continues to this day. I suspect it is common with all slotted rotors. It seems to me that the humming comes from all the rotors.
