GSsoldier Posted April 19, 2004 Share Posted April 19, 2004 i tend to get a shuddering in the LS when i apply the brakes why is that? does anyone else experience that in an 93 LS? if i can remember correctly it happens when im lowering my speeds from 60 to 40 on the highway or when im going normally and slow down at a light? it doesnt happen all the time but seems to happen at least once a day help give advice thanks everyone Quote Link to comment Share on other sites More sharing options...
SW03ES Posted April 19, 2004 Share Posted April 19, 2004 Sounds like slightly warped rotors to me... Quote Link to comment Share on other sites More sharing options...
VMF Posted April 19, 2004 Share Posted April 19, 2004 yeah, have them resurfaced, do front ones first since they are more susceptible for this kind of damage Quote Link to comment Share on other sites More sharing options...
99lsguy Posted April 19, 2004 Share Posted April 19, 2004 Agreed, Do this first....but if it still persists then worn suspension components (lower ball joint, strut bushings, tie rod bushings, etc) are next on the list ;) 99 Quote Link to comment Share on other sites More sharing options...
tansupplyman Posted April 19, 2004 Share Posted April 19, 2004 Have a dial micrometer clamped on each side first; max rotor runout is 0.05mm or 0.002 inch. If they are in spec, you are just throwing your money away !!!! All brake shops should have micrometers, go and ask price first--do not go to a Lexus dealer---they would probably want to SELL you new rotors before looking at them !!!!! Make sure they torque wheels to around 80 '# ; NOT to run nuts up with impact wrench !!! Quote Link to comment Share on other sites More sharing options...
