15044, small vibration when braking
Posted by MCubed45, Jan-19-03 04:10 PM
k i know that vibrations when you're braking is usually a sign that your rotors are warped but i was just kinda wondering whether it could be anything else. i recently did a complete brake upgrade and switched to gsx calipers and got the AEM AWD rotor upgrade. i took it to a brake shop to have everything installed (along w/ some SS lines too). the brake shop installed everything and even tested it and they told me that there was some slight pulsing coming from the brakes when braking. so it's kinda always done this since they were installed. the vibration is really slight but still somewhat noticable. it also only occurs at certain speeds when braking. like it'll usually happen when i'm slowing between maybe 20-30 mph. once i drop below 20 it's completely smooth. and there's no vibration if i'm somewhere above about 30 either. kinda weird.

i guess i'm just kinda wondering whether it's really the rotors (esp. since they're new). tia!

I'd maybe check the wheel bearings to be sure they are not loose or worn. It is possible to have an out of round rotor, even if its new, although its not very common. If the shop can put the rotors on a machining lathe, then it should be evident if they are not straight.
